Dear all,

May I ask whether there is any tool to help people to automatically
transfer C++ struct into C# struct?

Thank you very much!

Best Regards,
Tony

Tony, take a look at P/Invoke Interop Assistance utility.

http://msdn.microsoft.com/en-us/magazine/cc164193.aspx

It does a pretty good job and generating a translation for C/C++
structures and functions.

Example:

struct MyStruct {
int f1;
char *sz[255];
} ;

bool xyz(MyStruct *p);

generates:

[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
public struct MyStruct {

/// int
public int f1;

/// char*[255]

[System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.ByValArray,
SizeConst=255,
ArraySubType=System.Runtime.InteropServices.UnmanagedType.SysUInt)]
public System.IntPtr[] sz;
}

public partial class NativeMethods {

/// Return Type: boolean
///p: MyStruct*
[System.Runtime.InteropServices.DllImportAttribute("<Unknown>",
EntryPoint="xyz")]
[return:
System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.I1)]
public static extern bool xyz(ref MyStruct p) ;

}
