NET框架的所见即所得进度环(C#) [英] WYSIWYG Progress Circle for .NET Framework (C#)

问题描述

Application.DoEvents();语句立即显示进度圈，但在长时间运行任务时不会旋转.
请帮忙，我不知道我在做什么错.
我的示例代码:

Application.DoEvents(); statement shows the Progress circle immediately but it does not spin while long task is running.
Please help, I can''t figure out what I am doing wrong.
My sample code:

private void btnFindFileAndLoad_Click(object sender, EventArgs e)
{
    this.progressCircle1.Visible = true;
    this.progressCircle1.Rotate = true;
    Application.DoEvents();  //process message queue
    LoadMyFile(str_FileDirectory_and_FileName);  //runs for 20sec
	
    this.progressCircle1.Visible = false;
    this.progressCircle1.Rotate = false;
}

推荐答案

这是因为它在同一线程上.您需要在后台线程上运行进度圈或在后台线程上加载文件，并在后台线程完成后关闭进度圈.

It''s because it''s on the same thread. You need to run the progress circle on a background thread or load the file on a background thread and turn off the progress circle when the background thread completes.
