C＃後臺線程屬性丟失

Question

我想配置我的線程爲後臺線程，爲什麼這個屬性在我的線程中失蹤？

ThreadStart starter = delegate { openAdapterForStatistics(_device); }; 
    new Thread(starter).Start(); 

public void openAdapterForStatistics(PacketDevice selectedOutputDevice) 
{ 
    using (PacketCommunicator statCommunicator = selectedOutputDevice.Open(100, PacketDeviceOpenAttributes.Promiscuous, 1000)) //open the output adapter 
    { 
     statCommunicator.Mode = PacketCommunicatorMode.Statistics; //put the interface in statstics mode     
     statCommunicator.ReceiveStatistics(0, statisticsHandler); 

    } 
} 

我有嘗試：

Thread thread = new Thread(openAdapterForStatistics(_device)); 

，但我有2編譯錯誤：

1. 爲「System.Threading.Thread.Thread的最佳重載的方法匹配（系統.Threading.ThreadStart）'有一些無效參數
2. 參數1：無法從'void'轉換爲'System.Threading.ThreadStar T」

，我不知道爲什麼

Answer 1

關於後臺的事情，我不看你怎麼想到把它，因爲你不守的線程的引用。應該是這樣的：

ThreadStart starter = delegate { openAdapterForStatistics(_device); }; 
Thread t = new Thread(starter); 
t.IsBackground = true; 
t.Start(); 

這

Thread thread = new Thread(openAdapterForStatistics(_device)); 

不會起作用，因爲你應該在需要object作爲參數的方法來傳遞，而你實際上傳遞的結果方法調用方法調用。所以，你可以這樣做：

public void openAdapterForStatistics(object param) 
{ 
    PacketDevice selectedOutputDevice = (PacketDevice)param; 
    using (PacketCommunicator statCommunicator = selectedOutputDevice.Open(100, PacketDeviceOpenAttributes.Promiscuous, 1000)) //open the output adapter 
    { 
     statCommunicator.Mode = PacketCommunicatorMode.Statistics; //put the interface in statstics mode     
     statCommunicator.ReceiveStatistics(0, statisticsHandler); 

    } 
} 

和：

Thread t = new Thread(openAdapterForStatistics); 
t.IsBackground = true; 
t.Start(_device); 

Answer 2

您應該使用BackgroundWorker類，這是專門爲喜歡你的情況下使用而設計的。您希望在後臺完成的任務。

Answer 3

PacketDevice selectedOutputDeviceValue = [some value here]; 
Thread wt = new Thread(new ParameterizedThreadStart(this.openAdapterForStatistics)); 
wt.Start(selectedOutputDeviceValue);
