C＃Backgroundworker ConsoleWriteline(C# Backgroundworker ConsoleWriteline)

C＃Backgroundworker ConsoleWriteline(C# Backgroundworker ConsoleWriteline)

我有一个简单的Backgroundworker，想把我的结果写到控制台，我也想报告这个过程。

class Program { private static BackgroundWorker worker; static int counter; static void Main(string[] args) { worker = new BackgroundWorker(); worker.WorkerReportsProgress = true; worker.RunWorkerAsync(); Console.ReadLine(); } static void worker_DoWork(object sender, DoWorkEventArgs e) { while (true) { counter++; worker.ReportProgress(counter); } } static void worker_ProgressChanged(object sender, ProgressChangedEventArgs e) { Console.WriteLine(counter); } static void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { } }

但是，如何将我的String（或多于1个字符串）提供给我的ReportProcess函数？

I have a simple Backgroundworker and want to write my result to the Console and I also want to report the process.

class Program { private static BackgroundWorker worker; static int counter; static void Main(string[] args) { worker = new BackgroundWorker(); worker.WorkerReportsProgress = true; worker.RunWorkerAsync(); Console.ReadLine(); } static void worker_DoWork(object sender, DoWorkEventArgs e) { while (true) { counter++; worker.ReportProgress(counter); } } static void worker_ProgressChanged(object sender, ProgressChangedEventArgs e) { Console.WriteLine(counter); } static void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { } }

But how can I give my String (or more then 1 String) to my ReportProcess Function?

最满意答案

您没有将事件处理程序分配给BackgroundWorker事件：

static void Main(string[] args) { worker = new BackgroundWorker(); worker.DoWork += Worker_DoWork; //here worker.ProgressChanged += Worker_ProgressChanged; //and here worker.WorkerReportsProgress = true; worker.RunWorkerAsync(); Console.ReadLine(); }

干杯

You're not assigning the event handlers to the BackgroundWorker events:

static void Main(string[] args) { worker = new BackgroundWorker(); worker.DoWork += Worker_DoWork; //here worker.ProgressChanged += Worker_ProgressChanged; //and here worker.WorkerReportsProgress = true; worker.RunWorkerAsync(); Console.ReadLine(); }

Cheers
