How to marshal the type of "Cstring" in .NET Compact Framework(C#)?
DLLname:Test_Cstring.dll(OS is WinCE 5.0),source code:
extern "C" __declspec(dllexport) int GetStringLen(CString str)
{
return str.GetLength();
}
I marshal that in .NET Compact Framework(C#),for example:
[DllImport("Test_Cstring.dll", EntryPoint = "GetStringLen", SetLastError = true)]
public extern static int GetStringLen(string s);
private void Test_Cstring()
{
int len=-1;
len=GetStringLen("abcd");
MessageBox.Show("Length:"+len.ToString()); //result is -1,so PInvoke is unsuccessful!
}
The Method of "GetStringLen" in .NET CF is unsuccessful!
How to marshal this type of "Cstring"?
Any information about it would be very appreciated!
