原理就是在注册表启动项里添加一项。路径：SOFTWAREMicrosoftWindowsCurrentVersionRun或者直接：运行-regedit 找到这个路径添加一项。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 Microsoft.Win32;namespace CSharpStartpublic partial class Form1 : Form public Form1()InitializeComponent();private void btnSet_Click(object sender, EventArgs e)SetAutoRun(D:CSharpStart.exe,true);/ / 设置应用程序开机自动运行/ / 应用程序的文件名/ 是否自动运行，为 false 时，取消自动运行/ 设置不成功时抛出异常public static void SetAutoRun(string fileName, bool isAutoRun)RegistryKey reg = null;tryif (!System.IO.File.Exists(fileName)throw new Exception(该文件不存在! );String name = fileName.Substring(fileName.LastIndexOf() + 1);reg = Registry.LocalMachine.OpenSubKey(SOFTWAREMicrosoftWindowsCurrentVersionRun, true);if (reg = null)reg = Registry.LocalMachine.CreateSubKey(SOFTWAREMicrosoftWindowsCurrentVersionRun);if (isAutoRun)reg.SetValue(name, fileName);elsereg.SetValue(name, false);catch (Exception ex) throw new Exception(ex.ToString();finallyif (reg != null)reg.Close();/另外也可以写成服务，不过服务的话一般是在后台执行的，没有程序界面。或者直接：1. /添加启动2. RegistryKey ms_run = Registry.LocalMachine.OpenSubKey(SOFTWARE/Microsoft/Windows/CurrentVersion/Run, true);3. ms_run.SetValue(mistysoft, Application.ExecutablePath.ToString();4. /删除启动（设为控，注册表项还在）5. RegistryKey ms_run = Registry.LocalMachine.OpenSubKey(SOFTWARE/Microsoft/Windows/CurrentVersion/Run, true);6. ms_run.SetValue(mistysoft, );开机自启public static bool SetAutoRun(string keyName,string filePath)tryRegistryKey runKey=Registry.LocalMachine.OpenSubKey(SOFTWAREMicrosoftWindowsCurrentVersionRun,true);runKey.SetValue(keyName,filePath);runKey.Close();catchreturn false;return true;test: SetAutoRun(myexe,c:text.exe);另一个实例：宿舍的肥仔每次开机就需要运行多个程序，他希望一个程序实现这些事情，所以写了个程序，大家有什么意见可以给我提出来，我会多加修改，谢谢，贴上源码：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Diagnostics;using System.IO;namespace 懒人程序public partial class Form1 : Formpublic Form1()InitializeComponent();private void Form1_Load(object sender, EventArgs e)System.Diagnostics.ProcessStartInfo info=new System.Diagnostics.ProcessStartInfo();info.UseShellExecute = true;Process p;string path = C:a.txt;FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);StreamReader sr = new StreamReader(fs, Encoding.Default);string rl;while (rl = sr.ReadLine() != null)info.FileName = rl;/richTextBox1.AppendText(rl + n);p = Process.Start(info);sr.Close();fs.Close();Application.Exit();使用说明：先安装好软件，20 多 K 吧，运行前先在 c 盘根目录建立一个 a.txt，然后把需要同时运行的程序详细路径，包括程序名和 exe 后缀，一个程序占一行，可以同时有多行，例如：C:Program FilesInternet Exploreriexplore.exeC:Program FilesInternet Exploreriexplore.exe
