【C#技术】向窗体系统菜单添加自定义菜单

C# code

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Runtime.InteropServices;namespace WindowsFormsApplication3{    public partial class Form1 : Form    {        [DllImport("user32.dll")]        private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert);        [DllImport("user32.dll")]        private static extern bool InsertMenu(IntPtr hMenu,Int32 wPosition, Int32 wFlags, Int32 wIDNewItem,string lpNewItem);        public const Int32 WM_SYSCOMMAND = 0x112;        public const Int32 MF_SEPARATOR = 0x800;        public const Int32 MF_BYPOSITION = 0x400;        public const Int32 MF_STRING = 0x0;        public const Int32 MF_REMOVE = 0x1000;        public const Int32 IDM_EDITFUNDS = 1000;        public const Int32 IDM_ANALYZE = 1001;        //public const Int32 MF_CLOSE = &HF060;                public Form1()        {            InitializeComponent();        }        private void Form1_Load(object sender, EventArgs e)        {            IntPtr sysMenuHandle = GetSystemMenu(this.Handle, false);            InsertMenu(sysMenuHandle, 5, MF_BYPOSITION | MF_SEPARATOR, 0, string.Empty);            InsertMenu(sysMenuHandle, 6, MF_BYPOSITION, IDM_EDITFUNDS, "测试1");            InsertMenu(sysMenuHandle, 7, MF_BYPOSITION, IDM_ANALYZE, "测试2");        }        protected override void WndProc(ref Message m)        {            if (m.Msg == WM_SYSCOMMAND)            {                switch (m.WParam.ToInt32())                {                    case IDM_EDITFUNDS:                        MessageBox.Show("您单击了 测试1");                        return;                    case IDM_ANALYZE:                        MessageBox.Show("您单击了 测试2");                        return;                    default:                        break;                }            }            base.WndProc(ref m);        }    }}

另附一张我用C#高仿Adobe Photoshop CS6界面，项目还在完善中……
