遠程運行批處理文件，向用戶顯示結果並允許用戶提供輸入

我製作了一個頁面，允許用戶查看服務器上的批處理文件列表並運行它們。遠程運行批處理文件，向用戶顯示結果並允許用戶提供輸入

問題是批處理文件需要輸入如「按任意鍵繼續」或「如果您確定要繼續按Y」。目前我的代碼提供輸入預設情況：

if (outputLine.Contains("Y or N")) 
    inputLine = "Y"; 
if (outputLine.Contains("pause")) 
    inputLine = "X";

但我現在想給用戶提供的輸入，而不是我的代碼的能力。

我已經花了大部分時間研究如何做到這一點，並沒有提出任何建議。

這裏是我的代碼：

private void RunScript(int scriptId) 
{ 
    ScriptData data = new ScriptData(); 
    Script script = data.GetScript(scriptId); 

    ProcessStartInfo psi = new ProcessStartInfo() 
    { 
     FileName = script.Path, 
     RedirectStandardOutput = true, 
     RedirectStandardInput = true, 
     UseShellExecute = false, 
     CreateNoWindow = false 
    }; 

    Process proc = new Process(); 
    proc.StartInfo = psi; 

    proc.Start(); 

    StreamReader reader = proc.StandardOutput; 
    StreamWriter writer = proc.StandardInput; 

    string outputLine; 
    string inputLine = string.Empty; 
    string display = string.Empty; 

    while (!reader.EndOfStream) 
    { 
     outputLine = reader.ReadLine(); 
     display += outputLine + "\r\n"; 

     if (inputLine != string.Empty) 
      display += inputLine + "\r\n"; 

     inputLine = string.Empty; 
     if (outputLine.Contains("Y or N")) 
      inputLine = "Y"; 
     if (outputLine.Contains("pause")) 
      inputLine = "X"; 

     if (inputLine != string.Empty) 
      writer.WriteLine(inputLine); 
    } 

    display = Server.HtmlEncode(display); 
    display = display.Replace("\r\n", "<br />"); 
    litOutput.Text = display; 
}

終於解決了這個問題，我現在得到當我運行一個腳本是非常接近的命令提示符窗口。

下面是它的工作原理很基本的總結：

我開始運行一個批處理文件的新方法。同時，我開始一個新的線程，不斷循環詢問進程的更多輸出，並將該輸出存儲到隊列中。我的.NET計時器不斷檢查隊列中的文本，並將其輸出到我的ajax面板。我使用文本框和ajax將文本輸入到流程輸入和我的ajax面板中。還需要大量的JavaScript，我不得不使用會話變量使其運行順利。
