Converting wchar_t to Char

I need to convert:

wchar_t arr[20][32] 

To

char arr[20][32]

The conversion is done in the DLL (written in C++) and I want the values of arr to be displayed to the user in Windows Forms (written in C#).

Is it possible to display directly wchar_t in a textbox or should I convert from wchar_t to char in the DLL and then from char to string in Windows Forms?

How is this conversion do开发者_如何学Gone?

If the conversion is being done in C++, then take a look at WideCharToMultibyte function, defined in and exported from kernel32

If the conversion is being done in C#, look at the System.Text.ASCIIEncoding.ASCII.GetBytes(string) function to get an ASCII representation of a unicode string.
