啟動外部應用程式

開啟Notepad應用程式，編輯檔案test.dat。
程式碼

using System;
using System.Diagnostics ;

public class Sample
{
public static void Main()
{
Process pr = new Process();
pr.StartInfo.FileName = "Notepad.exe";
pr.StartInfo.Arguments = "test.dat";
pr.Start();

while (pr.HasExited == false)
if ((DateTime.Now.Second % 5) == 0)
{ // 每五秒顯示一個tick。
Console.Write(".");
System.Threading.Thread.Sleep(1000);
}
}
}

---

等待應用程式執行結束，並取得應用程式輸出字串。
程式碼

using System.Diagnostics;
private bool CommandLine(string args)
{
ProcessStartInfo proc = null ;
Process p=null ;
string res;
try
{
proc = new ProcessStartInfo(); // a process holder 

proc.FileName = "cmd.exe";
proc.CreateNoWindow = true;
proc.RedirectStandardInput = false;
proc.RedirectStandardOutput = true;

proc.Arguments = "/k "+args;
proc.UseShellExecute = false; /*do not show console for the process - a must*/

p = Process.Start(proc);

res = p.StandardOutput.ReadToEnd();
Output(res);
p.WaitForExit(); /*wait indefinitely for the associated process to exit*/
return true;
}
catch (Exception Ex)
{
Output (QONSOLE + ": " + Ex.Message);
return false;
}
finally
{
if (p != null) p.Close();
}
}
