Hos to convert string _gc* _gc* to wchat_t**

[Vinoth Kumar]

Hi

I am writing a wrapper class for a unmanaged c++ class, which has the method
signature,

Method(wchar_t* * ppszValue)

Anyone please tell me, how to convert the string _gc* _gc* to wchat_t**

Thanks in advance

Hello Vinoth,

Assuming you want to get an unmanaged string from a String* (managed), I
think one of these methods from ( System.Runtime. InteropServices .Marshal
) might help you:

public static IntPtr StringToBSTR(st ring s);
public static IntPtr StringToCoTaskM emAnsi(string s);
public static IntPtr StringToCoTaskM emAuto(string s);
public static IntPtr StringToCoTaskM emUni(string s);
public static IntPtr StringToHGlobal Ansi(string s);
public static IntPtr StringToHGlobal Auto(string s);
public static IntPtr StringToHGlobal Uni(string s);

Hope this helps,
RBischoff
