The following example uses the Process class itself and a static Start method to start a process.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        // Opens the Internet Explorer application. 
        void OpenApplication(string myFavoritesPath)
        {
            // Start Internet Explorer. Defaults to the home page.
            Process.Start("IExplore.exe");

            // Display the contents of the favorites folder in the browser.
            Process.Start(myFavoritesPath);
        }

        // Opens urls and .html documents using Internet Explorer. 
        void OpenWithArguments()
        {
            // url's are not considered documents. They can only be opened 
            // by passing them as arguments.
            Process.Start("IExplore.exe", "www.northwindtraders.com");

            // Start a Web page using a browser associated with .html and .asp files.
            Process.Start("IExplore.exe", "C:\\myPath\\myFile.htm");
            Process.Start("IExplore.exe", "C:\\myPath\\myFile.asp");

        }

        // Uses the ProcessStartInfo class to start new processes, 
        // both in a minimized mode. 
        void OpenWithStartInfo()
        {
            ProcessStartInfo startInfo = new ProcessStartInfo("IExplore.exe");
            startInfo.WindowStyle = ProcessWindowStyle.Minimized;

            Process.Start(startInfo);

            startInfo.Arguments = "www.northwindtraders.com";

            Process.Start(startInfo);

        }

        static void Main()
        {
            // Get the path that stores favorite links.
            string myFavoritesPath =
            Environment.GetFolderPath(Environment.SpecialFolder.Favorites);

            MyProcess myProcess = new MyProcess();

			myProcess.OpenApplication(myFavoritesPath);
			myProcess.OpenWithArguments();
			myProcess.OpenWithStartInfo();

        }
    }
}

The following example uses an instance of the Process class to start a process.

using System;
using System.Diagnostics;
using System.ComponentModel;

namespace MyProcessSample
{
    class MyProcess
    {
        public static void Main()
        {
            Process myProcess = new Process();

            try
            {
                myProcess.StartInfo.UseShellExecute = false;
                // You can start any process, HelloWorld is a do-nothing example.
                myProcess.StartInfo.FileName = "C:\\HelloWorld.exe";
                myProcess.StartInfo.CreateNoWindow = true;
                myProcess.Start();
                // This code assumes the process you are starting will terminate itself.  
                // Given that is is started without a window so you cannot terminate it  
                // on the desktop, it must terminate itself or you can do it programmatically 
                // from this application using the Kill method.
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
        }
    }
}

下列範例會啟動 [記事本] 程式的執行個體。
接著，它會在最多 10 秒鐘的期間，以 2 秒鐘為間隔，擷取相關處理序所耗用的實體記憶體。
該範例會偵測該處理序是否會在 10 秒鐘之內結束。
如果超過 10 秒鐘之後仍在執行，該範例就會關閉該處理序。
