Why can't I return a char* string from C++ to C# in a Release build?

Question

I\'m attempting to call the following trivial C function from C#:

SIMPLEDLL_API const char* ReturnString()
{
    return \"Returning a static string!\";
}
         


        

Answer 1

Or maybe try to use

[DllImport("SimpleDll")]
public static extern IntPtr ReturnString();

and in your calling code, use the Marshal Class

string ret = System.Runtime.InteropServices.Marshal.PtrToStringAnsi(PInvoke.ReturnString());
