enum property type (e.g. string, int) RRS feed

  • Question

  • User2074931137 posted

    Why would the enum property not indicate what type of field it is?  Why wouldn't it be string or int?

            public Property101? Property101 { get; set; }


    Full code follows...

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    // end default
    using System.ComponentModel.DataAnnotations.Schema;
    
    
    namespace ModelWebApplication.Models
    {
        public enum Property101
        {
            A, B, C, D, F
        }
        public class Class101
        {
            public int Class101ID { get; set; }
    
            public int Class01ID { get; set; }
            public int Class02ID { get; set; }
    
            public Property101? Property101 { get; set; }  // ("Enum," "Nullable," "Payload")
    
            public virtual Class01 Class01 { get; set; }
            public virtual Class02 Class02 { get; set; }
        }
    }

    @mbanavige

    Mike B. your lexical analysis (sic) of the O.P.'s question has led you to a faulty conclusion.

    Let me explain.

    (a) the O.P.'s subject:     enum property type (e.g. string, int)

             [[[enum] property] type]   [ (e.g. string, int)]

    • The O.P. is asked about enum
    • The O.P. falsely assumes that there is such a thing as an enum property 
    • The O.P. wonders what is the type of the enum property

    However, https://msdn.microsoft.com/en-us/library/sbbt4032.aspx "enum (c# reference)

    1. enum is a c# keyword
    2. The enum keyword is used to declare an enumeration
    3. an enumeration is a distinct type
    4. an enumeration consists of set of named constants called the enumerator list.

    (b)  the O.P.'s first sentence is:

    "Why would the enum property not indicate what type of field it is?  Why wouldn't it be string or int?"

    https://msdn.microsoft.com/en-us/library/ms173118.aspx "Fields (C# Programming Guide)

    field is a variable of any type that is declared directly in a class or struct.

    Fields are members of their containing type.

    https://msdn.microsoft.com/en-us/library/bb384054.aspx "Auto-Implemented Properties (C# Programming Guide)"

    "When you declare [an auto-implemented] property ... , the compiler creates a private, anonymous backing field that can only be accessed through the property's get and set accessors." 

    "backing fields ... are not accessible from your source code"

    public Property101? Property101 { get; set; }

    public
    Property101?   <== this is the type of the member "Property101";
                                    the question mark declares it nullable
    Property101  <== this is an auto-implemented property
    { get; set; }

    Whether aware, or not, the O.P. is essential asking either about the type of the class member Class101.Property101 or the type of that class member's underlying backing field (to which there is not source code access).

    (c) let's ask the ultimate authority, the c# compiler:

    public enum Property101
    {
        A, B, C, D, F
    }
    public class Class101
    {
        public Property101? Property101 { get; set; }  // ("Enum," "Nullable," "Payload")
    }
    void Main()
    {
        Console.WriteLine (Property101);  // we can not do this

    compiler error:  Property101' is a 'type' but is used like a 'variable'

    we can not ask the type of a type

    void Main()
    {
        Class101 class101 = new Class101();
        Console.WriteLine (class101.Property101);  // we can do this, the value is null
        Console.WriteLine (class101.Property101.GetType()); // this causes a run time exception

    NullReferenceException 
    Object reference not set to an instance of an object.

    Since the class Class101 member Property101 has been declared nullable .GetType can not return type information while the value isnull.

    void Main()
    {
        Class101 class101 = new Class101();
        class101.Property101 = Property101.F;          
        Console.WriteLine (class101.Property101);  // we can do this, the value written is 'F'
        Console.WriteLine (class101.Property101.GetType()); // this does NOT cause a run time exception

    running the above code, we are informed that class101.Property101.GetType() is

                     Property101

    not            int

    of course it's not int which is the REASON why if we want to use its integer value, we must perform a cast!

    Can you explain your question a bit more? 

    What are you trying to do?  Can you state your problem without using negatives ("not indicate", "why wouldn't")?  Can you tell us positively what you are seeing and what you are expecting?

    The code you have shown appears to be correct.

    @3v3rhart

    Note:  use names meaningful to your application, for example, instead of Property101:  

    public enum Colours
    {
        Amber, Blue, Chocolate, DarkBlue, Evergreen
    }

    Note:  avoid this because the code can be confusing:

    public Property101? Property101 { get; set; }  // ("Enum," "Nullable," "Payload")

    Prefer instead something like this in your class:

    public Colours? SeatColour { get; set; }  // ("Enum," "Nullable," )
    

    https://msdn.microsoft.com/en-us/library/sbbt4032.aspx    "enum (C# Reference)"

    "The enum keyword is used to declare an enumeration,
     a distinct type that consists of a set of named constants called the enumerator list.

    your code, just the important parts with regards to your question:

    public enum Property101
    {
        A, B, C, D, F
    }
    public class Class101
    {
        public Property101? Property101 { get; set; }  // ("Enum," "Nullable," "Payload")
    }

    (a) making the type of the class member Property101 as nullable Property101? is likely a bad design decision:

    void Main()
    {
        Class101 class101 = new Class101();
        Console.WriteLine (class101.Property101.Value);     // GENERATES "Invalid Operation Exception"
        Console.WriteLine (class101.Property101.GetType());
    }

    Better is:

    public enum Property101
    {
        undefined = 0, A, B, C, D, F
    }
    public class Class101
    {
        public Property101 Property101 { get; set; }  // ("Enum," "Not Nullable," "Payload")
    }
    void Main()
    {
        Class101 class101 = new Class101();
        Console.WriteLine (class101.Property101);
    }

    output:

    undefined
    Property101

    N.B.:      via Intellisense, if in Main() you type

    Property101.

    you will see values but you will not see GetType() 

    for

    class101.Property101.

    you will not see the values in Intellisense .

    important:  The approved types for an enum are bytesbyteshortushortintuintlong, or ulong.

    also:  The underlying type specifies how much storage is allocated for each enumerator.
    However, an explicit cast is necessary to convert from enum type to an integral type.

    YOUR QUESTION:

    Why would the enum property not indicate what type of field it is?  Why wouldn't it be string or int?

    ANSWER:  enum is not property ... your enum named Property101 by you is the type of your class member also named by you as Property101.

    Study the c# reference article about the enum keyword.

    enum is an int , usually.

    actually ignat, this is not true.  

    "The enum keyword is used to declare an enumeration,
     a distinct type that consists of a set of named constants called the enumerator list.

    Proof:  for enums, a cast is required.  For int to int c# does not require a cast.

         "The enum keyword is used to declare an enumeration,
          a distinct type that consists of a set of named constants called the enumerator list.

    i.e., enum is not an int but a distinct type.

    enum integerColours : int {green, pink, yellow}
    void Main()
    {
        int grass = integerColours.green; // with out a cast
    }

    compile error:

    Cannot implicitly convert type 'integerColours' to 'int'.
    An explicit conversion exists (are you missing a cast?)

    correct is:

    int grass = (int)integerColours.green; // with a cast

    compiler error:  Property101' is a 'type' but is used like a 'variable'

    we can not ask the type of a type

    void Main()
    {
        Class101 class101 = new Class101();
        Console.WriteLine (class101.Property101);  // we can do this, the value is null
        Console.WriteLine (class101.Property101.GetType()); // this causes a run time exception

    NullReferenceException 
    Object reference not set to an instance of an object.

    Since the class Class101 member Property101 has been declared nullable .GetType can not return type information while the value isnull.

    void Main()
    {
        Class101 class101 = new Class101();
        class101.Property101 = Property101.F;          
        Console.WriteLine (class101.Property101);  // we can do this, the value written is 'F'
        Console.WriteLine (class101.Property101.GetType()); // this does NOT cause a run time exception

    running the above code, we are informed that class101.Property101.GetType() is

                     Property101

    not            int

    of course it's not int which is the REASON why if we want to use its integer value, we must perform a cast!
