C# .NET class getter/setter shorthand

Question

User653228039 posted

I remember a friend of mine showing me a nifty shorthand in .NET where you could identify a class's members and getters/setters in a very concise way.  Like "get:" and "set:" were in the same code block.  Anyone know what I'm talking about?  Could someone show me a sample class that has one member and a getter/setter using this shorthand?

public class Person
{
    //default constructor 
    public Person()
	{
	}

    private string _Name;
    public string Name
    {
        //set the person name
        set { this._Name = value; }
        //get the person name 
        get { return this._Name; }
    }
}

Hi,

try this

public class MyClass

{

     private int _id;

     public int Id

     {

             get { return _id;}

             set { _id = value;}  

     }     

}

Regards

That was the one.  Thanks to both of you!

 

Turns out newer versions of C# supposedly support an even more concise declaration (though I haven't been able to verify because I am on an older server):

 

public class Person
{
    public string Firstname { get; set; }
    public string Middlename { get; set; }
    public string Lastname { get; set; }
    public int Age { get; set; }
} 

Now that's concise!

 I realize I'm way late on this one, but you are correct, C# v3.5 has those shorthand declarations...

 public string MyString { get;set; }

 
 ...which creates a private variable with the default public accessors (getters/setters), which is basically equivalent to...

private string _myString;

public string MyString
{
    get { return _myString; }
    set { _myString = value; }
}

...and unfortunately VB.NET (my client's requirement, argh) has no such shortcut, which is how I came upon this post... trying to find one (pain in the...)

Yeah, that is probably the biggest reason I prefer C# over VB.  VB code tends to be pretty wordy and it just feels like I'm writing a novel sometimes instead of code.  :-P

this is a quick and easy way to do the getter and setter of the field but I am just wondering what is the difference between this approach and the traditional approach in a simple class not in the polymorphism 

private int _id;

public void SetId (int id) 
{
_id = id;
}
public int GetId()
{
return _id;
}

public string Name { get; set; }  is what I use, when i simply need a getter and setter, no need to even declare the private string _name.  

Though if you want to do more with your code (check validation, equations, or anything) you need to write it all out

private string _name
public void Name(string _name)
{
_name + " smith" = Name;
}
