다음 명령을 시작하기 전에 각 명령이 완료되기를 기다리는 여러 명령을 어떻게 실행할 수 있습니까?

Question

다음 명령을 시작하기 전에 각 명령이 완료되기를 기다리는 명령을 세 개 있습니다.

첫 번째 작업을 완료 한 후 내 구현을 기반으로하지만 두 번째 작업은 시작되지만 backgroundWorker1_RunWorkerCompleted는 전혀 발생시키지 않습니다.

using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace cmd_commands 
{ 
    public partial class Form1 : Form 
    { 
     string[] commands = new string[] { 
     @"test", 
     @"test1", 
     @"test2" }; 

     int command = 0; 

     public Form1() 
     { 
      InitializeComponent(); 
     } 

     public void runCmd(string command) 
     { 
      ProcessStartInfo cmdsi = new ProcessStartInfo("cmd.exe"); 
      cmdsi.Arguments = command; 
      Process cmd = Process.Start(cmdsi); 
      cmd.WaitForExit(); 
     } 

     private void Form1_Load(object sender, EventArgs e) 
     { 

     } 

     private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) 
     { 
      runCmd(commands[command]); 
      backgroundWorker1.ReportProgress(0, command); 
     } 

     private void button1_Click(object sender, EventArgs e) 
     { 
      backgroundWorker1.RunWorkerAsync(); 
     } 

     private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) 
     { 
      label1.Text = "Working on command number: " + e.UserState.ToString(); 
     } 

     private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) 
     { 
      command++; 
      runCmd(commands[command]); 
     } 
    } 
}

BackgroundWorker는 한 번만 상태가 완료되면 다시 시작하지 않으므로 다시 인스턴스화해야합니다.

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) 
{ 
    command++; 

    if (command < commands.Length) 
    { 
     backgroundWorker1 = new BackgroundWorker(); 
     backgroundWorker1.DoWork += this.backgroundWorker1_DoWork; 
     backgroundWorker1.ProgressChanged += this.backgroundWorker1_ProgressChanged; 
     backgroundWorker1.RunWorkerCompleted += this.backgroundWorker1_RunWorkerCompleted; 
     backgroundWorker1.RunWorkerAsync(); 
    } 
}
