[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)]
public struct MyStruct
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=4)] public string fname;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=4)] public string lname;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=7)] public string phone;
}
public static void Main()
{
string buffer = "abcdefgh2223333";
IntPtr pBuf = Marshal.StringToBSTR(buffer);
MyStruct ms = (MyStruct)Marshal.PtrToStructure(pBuf,typeof(MyStruct));
Console.WriteLine("fname is: {0}",ms.fname);
Console.WriteLine("lname is: {0}",ms.lname);
Console.WriteLine("phone is: {0}",ms.phone);
