本文介绍使用C#拷贝String到struct 。

代码

using System;

using System.Runtime.InteropServices;

using System.Text;

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);

}
