class Class1

{

    [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);
