C# winform程序怎樣將程序最小化到系統托盤？

這樣最簡單！

1.在form中添加一個NotifyIcon控件

2.把icon.ico這個圖標放在/bin/Debug目錄下

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace MinimizeForm
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
            notifyIcon1.Icon = new Icon(Application.StartupPath "//icon.ico");//指定一個圖標
            notifyIcon1.Visible = false;
            notifyIcon1.Click += new System.EventHandler(this.notifyIcon1_Click);
            this.SizeChanged += new System.EventHandler(this.Form1_SizeChanged);
        }
        private void Form1_SizeChanged(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)//最小化
            {
                this.ShowInTaskbar = false;
                this.notifyIcon1.Visible = true;
            }
        }
              private void notifyIcon1_Click(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
                this.WindowState = FormWindowstate.Normal;
            this.Activate();
            this.notifyIcon1.Visible = false;
            this.ShowInTaskbar = true;
        }
    }
}
