获取常用系统文件目录

static void Main(string[] args){    //1、通过Environment.GetFolderPath()获取    string pathFavorites = Environment.GetFolderPath(Environment.SpecialFolder.Favorites);//获取我的收藏路径    Console.WriteLine("Favorites:" + pathFavorites);    string pathDesktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);//获取桌面路径    Console.WriteLine("Desktop:" + pathDesktop);    string pathMyDocuments = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);//获取我的文档路径    Console.WriteLine("MyDocuments:" + pathMyDocuments);    string pathMyPictures = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures);//获取我的图片路径    Console.WriteLine("MyPictures:" + pathMyPictures);    string pathMyVideos = Environment.GetFolderPath(Environment.SpecialFolder.MyVideos);//获取我的视频路径    Console.WriteLine("MyVideos:" + pathMyVideos);    string pathDownloads = Environment.GetFolderPath(Environment.SpecialFolder.UserProfile) + "\\Downloads";//获取下载路径（这个没有找到，所以需要配合UserProfile来拼接了）    Console.WriteLine("Downloads:" + pathDownloads);    //2、通过环境变量获取    string tempPath = Environment.GetEnvironmentVariable("TEMP");    Console.WriteLine("TEMP:" + tempPath);    Console.ReadKey();}

设置开机启动

private string registryName = "BootTestDemo";//启动项的名称private void btnSubmit_Click(object sender, EventArgs e){    if (this.ckBootEntry.Checked)    {        string filePath = Environment.CurrentDirectory + "\\PowerBootDemo.exe";        SetBoot(this.registryName, filePath);    }    else    {        DeleteBoot(this.registryName);    }    MessageBox.Show("Success");}/// <summary>/// 检测注册项是否存在/// </summary>/// <param name="key"></param>/// <returns></returns>private bool CheckExisting(string key){    string[] allNames = Microsoft.Win32.Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run").GetValueNames();    foreach (var item in allNames)    {        if (item.Equals(key))        {            return true;        }    }    return false;}/// <summary>/// 设置启动项/// </summary>private void SetBoot(string key, string path){    if (CheckExisting(this.registryName)) return;//检测是否存在    Microsoft.Win32.RegistryKey registryKey = Microsoft.Win32.Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");//在系统启动的注册表中创建子项    registryKey.SetValue(key, path);//为子项进行赋值}/// <summary>/// 删除启动项/// </summary>public void DeleteBoot(string key){    if (!CheckExisting(this.registryName)) return;//检测是否存在    Microsoft.Win32.RegistryKey registryKey = Microsoft.Win32.Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");    registryKey.DeleteValue(key, false);}//PS：如果记不住这么长的路径可以直接打开系统注册表编辑器来翻看（cmd执行：regedit）。
