让WPF UI响应当执行按一下按钮

问题描述：

在我的WPF（C＃）的应用中，当一个按钮被用户按下，执行一个漫长的过程。当按下按钮，直到完整的代码执行的窗口冻结，用户不能执行在窗口中的任何其他任务。我怎样才能使按钮单击代码作为后台进程，使窗口成为响应用户。我曾尝试以下方法，但没有成功。

In my wpf (c#) application , a long process is performed when a button is pressed by the user. When button is pressed until the complete code executed the window freezes and user cannot perform any other task in the window. How can I make the button click code as a background process, so that the window become responsive to the user. I have tried the following method, but was unsuccessful.

private void btn_convert_Click(object sender, RoutedEventArgs e)
{
    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background, 
    new Action(() => { 

         WorkerMethod();
    }));
}

在哪里WorkerMethod与整个代码的功能。任何suggessions。

Where WorkerMethod is the function with the entire code. Any suggessions.

问候，结果

答

您实际上已经在这里做了什么要求UI线程来运行通过调度的重任。

What you have actually done here is asking the UI thread to run your heavy task through the Dispatcher.

您应该创建一个新的线程/任务，并让它运行你的背景方法：

You should create a new thread/Task and let it run your background Method:

Thread t = new Thread(() => WorkerMethod());
t.Start();
