用於例如假設我有VLC或iTunes或任何Windows應用程序那我怎麼才能弄明白的C＃代碼如果它正在運行或沒有運行。

Answer 1

這應該是很容易找到一個快速谷歌搜索，但在這裏你去：

if (Process.GetProcessesByName("process_name").Length > 0) 
{ 
    // Is running 
} 

更換process_name與過程的您正在尋找（即vlc）的名稱。

試試這個

public partial class App : System.Windows.Application 
    { 
     public bool IsProcessOpen(string name) 
     { 
      foreach (Process clsProcess in Process.GetProcesses()) 
      { 
       if (clsProcess.ProcessName.Contains(name)) 
       { 
        return true; 
       } 
      } 
      return false; 
     } 

     protected override void OnStartup(StartupEventArgs e) 
     { 
      // Get Reference to the current Process 
      Process thisProc = Process.GetCurrentProcess(); 
      if (IsProcessOpen("name of application.exe") == false) 
      { 
       //System.Windows.MessageBox.Show("Application not open!"); 
       //System.Windows.Application.Current.Shutdown(); 
      } 
      else 
      { 
       // Check how many total processes have the same name as the current one 
       if (Process.GetProcessesByName(thisProc.ProcessName).Length > 1) 
       { 
        // If ther is more than one, than it is already running. 
        System.Windows.MessageBox.Show("Application is already running."); 
        System.Windows.Application.Current.Shutdown(); 
        return; 
       } 
      base.OnStartup(e); 
     } 
}

您可以使用Process.GetProcessesByName，如果你知道進程的名稱或Process.GetProcessesByID，如果你知道它的ID。
