How to copy contents of an array into a string

Question

Hello,  its been 4 days that I am stuck like a donkey in mud.
(BTW, i did review similar questions but no help)

I have an array that has been initialized like this


/////////////////////C O D E ///////////////////////////
array<Char>^   arr;
String^             Str;

arr = gcnew array<Char> (5);

arr[0] = 'a';
arr[1] = 'b';
arr[2] = 'c';
arr[3] = 'd';
arr[4] = 'e';
////////////////////////////////////////////////////////

so far so good, I created an array of size 5 and inserted characters 'a','b','c','d' and 'e' into its elements.

Now here is my simple question:  HOW CAN I TRANSFER THE CONTENT OF THE ARRAY(arr[]) into the string Str ? So Str should contain this "abcde"  ? Is there a simple method?


Thank you

Answer 1

Hi, I think this what u want

#include<iostream>
#include<string>
using namespace std;
void main()

{

char arr[6]={'a','b','c','d','e'};

string str;
str=arr;

cout<<str<<endl;

//u can also do this

cout<<arr<<endl;

}

I hope it's helpfull :)

Hello Krvcun,

String has constructor to take Char array. See the code snippet.

 array<Char>^  arr;
 String^       Str;

 arr = gcnew array<Char> (5);

 arr[0] = 'a';
 arr[1] = 'b';
 arr[2] = 'c';
 arr[3] = 'd';
 arr[4] = 'e';

 // String has constructor to take Char array.
 Str = gcnew String( arr );

Best Regards,
Jijo.

No syrian star, it didn't help, please note that my project is a 'windows form' project.  It is so unforgiving.  The slightest things I do, I get compiler error(where used to be OK with the regular 'C' I used to work with in the past) .  For example, I have tried  the one line of code you have suggested --->  str=arr;  but it generates compiler error on type conversion,  I have also tried the following two lines of code with no compiler errors, but still str it is NOT set to "abcde" :

str =

dynamic_cast<String^>(arr);

str = arr->ToString();

You have to understand that when you use WinForms in Visual C++, you are not using C++, but rather a new language called C++/CLI. C++/CLI is essentially a combination of standard C++ and C# in a single (rather complex) language.

You should also know that Microsoft is no longer promoting C++/CLI as a means of developing .NET GUI programs. Rather you should use C# for managed .NET applications (WinForms or WPF) or standard C++ with MFC for native (unmanaged) applications.

The intended use for C++/CLI is "wrapping" native C++ code into managed class libraries that can be used from C# or VB.NET.

OH MY GOD, YOU JUST SHED BIG LIGHT ON MY DARKNESS,  THANK YOU davewilk

I knew something was fishy here?

I am little clueless on these things.   PLEASE HELP
OK, so I have to use C# for managed .NET applications, 

Here comes my BIG question:

---> To use C# for managed .NET applications, can I still use VC++ 2008 Express Edition by just creating a new PROJECT with different properties to make it C# for managed .NET applications and then transfer/convert my existing code into that ?

If the anwser to the BIG question is 'NO ', then what should I use ?


Thank you

Answer 7

You should use Visual C# Express.

Thank you Davewilk, if it was up to me you would get your sixth medal !

I hope Visual C# Express is also free like VC++

Indeed. All express editions are free.
