本文介绍如何使用C#通过Process类启动外部应用程序，并获取其输出。具体包括设置应用程序路径、命令行参数，以及如何配置ProcessStartInfo来避免显示命令窗口并重定向标准输出。

// This snippet needs the "System.Diagnostics"
// library

// Application path and command line arguments
string ApplicationPath = "C://example.exe";
string ApplicationArguments = "-c -x";

// Create a new process object
Process ProcessObj = new Process();

// StartInfo contains the startup information of
// the new process
ProcessObj.StartInfo.FileName = ApplicationPath;
ProcessObj.StartInfo.Arguments = ApplicationArguments;

// These two optional flags ensure that no DOS window
// appears
ProcessObj.StartInfo.UseShellExecute = false;
ProcessObj.StartInfo.CreateNoWindow = true;

// If this option is set the DOS window appears again
// ProcessObj.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

// This ensures that you get the output from the DOS application
ProcessObj.StartInfo.RedirectStandardOutput = true;

// Start the process
ProcessObj.Start();

// Wait that the process exits
ProcessObj.WaitForExit();

// Now read the output of the DOS application
string Result = ProcessObj.StandardOutput.ReadToEnd();
