C#中关于进程的一些常用操作

    public static void StartProgram(string directory,string fileName)
    {
        Process mainprocess = new Process();
        mainprocess.StartInfo.WorkingDirectory = directory;
        mainprocess.StartInfo.FileName = fileName;//其实可以不指定上面的目录，这里写成directory + filename亦可
        mainprocess.StartInfo.Arguments = "ok";//这里可以给其他进程（exe文件）传递参数
        mainprocess.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
        mainprocess.Start();
    }

    //另一进程
    static Class Program
    {
        static void Main(string[] arguments) {    
                string arg = arguments[0];//arg="ok";
        }

    }  

            //杀死进程，这里的processName不能带.exe，谨记！！！
        public static void KillProcess(string processName)
        {
            Process myproc = new Process();
            try
            {
                foreach (Process proc in Process.GetProcessesByName(processName))
                {
                    if (!proc.CloseMainWindow())
                    {
                        proc.Kill();
                    }
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

         private void PrintDoc()
        {
            //定义一个进程实例
            System.Diagnostics.Process myProcess = new System.Diagnostics.Process();
            try
            {
                //设置进程的参数
                string myDocumentsPath = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
                myProcess.StartInfo.FileName = myDocumentsPath + "\TxtForTest.txt";
                myProcess.StartInfo.Verb = "Print";
                //显示txt文件的所有谓词
                foreach (string v in myProcess.StartInfo.Verbs)
                MessageBox.Show(v);
                myProcess.StartInfo.CreateNoWindow = true;
                //启动进程
                myProcess.Start();
            }
            catch (Win32Exception e)
            {
                if (e.NativeErrorCode == ERROR_FILE_NOT_FOUND)
                {
                MessageBox.Show(e.Message + " Check the path." + myProcess.StartInfo.FileName);
                }
                else if (e.NativeErrorCode == ERROR_ACCESS_DENIED)
                {
                MessageBox.Show(e.Message + " You do not have permission to print this file.");
                }
            }
        }

//启动浏览器：
Process.Start("IExplore.exe");
//打开浏览器，并跳转到指定的网址：
Process.Start("IExplore.exe", "http://www.cnblogs.com/ddhj/");

如果Start的是文件夹路径，而不是文件路径，将会打开此文件夹：
string myFavoritesPath = System.Environment.GetFolderPath(Environment.SpecialFolder.Favorites);//获取“收藏夹”文件路径
//启动进程
System.Diagnostics.Process.Start(myFavoritesPath);

打开文件夹：

System.Diagnostics.Process.Start(FilePath);

打开文件夹中某个文件：

System.Diagnostics.Process.Start(FilePath+"/"+FileName);

打开文件夹并选中单个文件：

System.Diagnostics.Process.Start("Explorer", "/select,"+ FilePath+"\"+FileName);

或

System.Diagnostics.Process.Start("Explorer.exe", "/select,"+ FilePath+"\"+FileName);

用IE打开文件:

System.Diagnostics.Process.Start("Explorer",FilePath+"\"+FileName);

System.Diagnostics.Process.Start("Explorer.exe",FilePath+"\"+FileName);

注：（explorer,explorer.exe,select,不区分大小写,"/selecet,"其中"/,"都不能少,FilePath为文件路径不包含文件名)

 打开文件夹并选中网页

System.Diagnostics.Process.Start("Explorer.exe", ”http://www.sunwale.com/“);
