从字节数组中读取C#中的C/C++数据结构

using System;
using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]
public struct MyStruct
{
    public int field1;
    public byte field2;
    public short field3;
}

public class Program
{
    public static void Main()
    {
        byte[] byteArray = new byte[] { 0x12, 0x34, 0x56, 0x78, 0x9A };

        GCHandle handle = GCHandle.Alloc(byteArray, GCHandleType.Pinned);
        MyStruct myStruct = (MyStruct)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(MyStruct));
        handle.Free();

        Console.WriteLine("field1: {0}", myStruct.field1);
        Console.WriteLine("field2: {0}", myStruct.field2);
        Console.WriteLine("field3: {0}", myStruct.field3);
    }
