    Post C++/CLI...convert wchar_t array to System::String^

    Hi. I am currently learning to use Visual C++ from the the Ivor Horton book.

    I was just practicing something and i came across a point where i needed to convert an array of wchar_t elements to a System::String^ type.

    Example:

    String^ parse(String^ str)
    {
    wchar_t ch = ' '
    array<wchar_t>^ returnstr = gcnew array<wchar_t>(10);
    int pos = str->IndexOf(ch);
    str->CopyTo(0, returnstr, 0, pos);

    return returnstr->ToString();
    }

    int main(array<System::String^> ^args)
    {
    String^ str = L"Hello! one two three";
    String^ p = parse(str);

    Console::WriteLine(p);
    return 0;
    }

    --------------------------
    I'm Getting This output>>>

    System.Char[]
    Press any key to continue...

    -------------------------
    My required Output>>>

    Hello!
    Press any key to continue...

    -------------------------

    What my objective for this program is to just display "Hello!" from the "Hello! one two three" string.
    And what i REALLY WANT TO TRY is returning a String^ type from the array of wchar_t elements (returnstr).

    You may modify the code and show it as your answer..

    Thanks!

    Dead easy :

    Code:
    const wchar_t *test = L"hello there";
    String ^xx = gcnew String(test);

    Or in your case :

    Code:
    wchar_t ch = ' '
    array<wchar_t>^ returnstr = gcnew array<wchar_t>(10);
    int pos = str->IndexOf(ch);
    str->CopyTo(0, returnstr, 0, pos);
    
    return gcnew String(returnstr);
