如何在c＃中加载long方法时显示进度 [英] How to show a progress from while loading a long method in c#

问题描述

我希望在C＃中运行方法时显示'请等待加载...'表单的进度。



我已经取了一个按钮我已经编写了一个方法代码。当我们点击该按钮时，进度表将打开，直到方法处于进行状态。

I want to show a progress from i.e 'Please wait loading...' form while running a method in C#.

I have taken one button in that i have written one method code.when we click on that button then the progress form will open until method has in progress state.

BackgroundWorker bg = new BackgroundWorker();
            bg.DoWork += new DoWorkEventHandler(bg_DoWork);
            bg.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bg_RunWorkerCompleted);
            // Start the worker.
            bg.RunWorkerAsync();
            // Display the loading form.
            popup pp = new popup();
            pp.ShowDialog();

private void bg_DoWork(object sender, DoWorkEventArgs e)
      {
copy();
}

private void bg_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
   {
   object result = e.Result;
   pp.Close();
   }

但是显示一个错误
