線程在asp.net崩潰的服務器

Question

嘿傢伙，我試圖讓線程工作在ASP.NET中，但由於某種原因，它不斷崩潰我的本地服務器，並根本不工作時，在網上上傳。這裏的代碼：

protected void testThread() 
{ 
    for (int i = 0; i < 10; i++) 
    { 
     Response.Write("Threading! <br/><br/>"); 
     Thread.Sleep(500); 
    } 
} 

protected void Button1_Click(object sender, EventArgs e) 
{ 

    Thread oThread = new Thread(testThread); 
    oThread.Priority = ThreadPriority.Lowest; //Tried with and without this 

    // Start the thread 
    oThread.Start(); 
} 

任何想法？

像什麼@Daniel說，Response可能已經被時間的線程運行終止。解決方案是在線程運行時保持連接處於活動狀態。我們可以通過分配和異步任務來完成這項工作。

protected void Page_Load(object sender, EventArgs e) 
{ 
    AddOnPreRenderCompleteAsync(new BeginEventHandler(Thread_BeginEvent), new EndEventHandler(Thread_EndEvent)); 
} 
protected override void OnPreRender(EventArgs e) 
{ 
    base.OnPreRender(e); 
    Response.Write(result); 
} 

private string result; 

IAsyncResult Thread_BeginEvent(object sender, EventArgs e, AsyncCallback cb, object extraData) 
{ 
    WaitCallback w = new WaitCallback(Thread_DoWork); 
    return w.BeginInvoke(sender, cb, extraData, w); 
} 
void Thread_EndEvent(IAsyncResult ar) 
{ 
    WaitCallback w = ar.AsyncState as WaitCallback; 
    if(w != null) 
     w.EndInvoke(ar); 
} 

void Thread_DoWork(object state) 
{ 
    result = ""; 
    for (int i = 0; i < 10; i++) 
    { 
     result += "Threading! <br/><br/>"; 
     Thread.Sleep(500); 
    } 
} 

你可能想試試這個爲好，但我不知道它是否有效與否，但我懷疑這會：

void Thread_DoWork(object state) 
{ 
    for (int i = 0; i < 10; i++) 
    { 
     Response.Write("Threading! <br/><br/>"); 
     Thread.Sleep(500); 
    } 
}

HTTP Response已經（非常有可能）在線程再次擊中它時發送。線程在ASP.NET頁面生命週期中效果不佳。考慮改變你的過程。

看到這個頁面的挑戰。

protected void Button1_Click(object sender, EventArgs e) 
{ 

    Thread oThread = new Thread(testThread); 
    oThread.Priority = ThreadPriority.Lowest; //Tried with and without this 

    // Start the thread 
    oThread.Start(); 

    oThread.Join() 
    // defeats the purpose of multithreading, but you can't 
    // let the main thread return if the newly spawned thread 
    // it trying to use Response object. 
}
