无限循环中的doevent() [英] doevent() in the infinite loop

问题描述

除了doevent()是在此无限循环中以形式运行另一个控件的另一种方式.

我想和backgroundworker一起做，但是失败了！！

Except doevent() is another way that, in this infinite loop run another control in form.

I wanted to do it With backgroundworker, but I failed.!

private void button1_Click(object sender, EventArgs e)
     {
         while (true)
         {

         }
     }

推荐答案

如果我已正确理解要执行的操作，则需要将while循环及其包含的任何代码替换为BackgroundWorker .

您声明自己尝试了BackgroundWorker并失败了，但是如果不查看while循环内的代码以及尝试的BackgroundWorker的外观，很难给出更多建议.

If I have understood what you want to do correctly, you need to replace your while loop and whatever code it contains by a BackgroundWorker.

You state that you tried a BackgroundWorker and failed but it is very difficult to give more advice without seeing the code inside the while loop and what the BackgroundWorker you tried looks like.

合理的示例我的其他答案中显示了如何使用BackgroundWorker:
逐步更改以显示控件 [ ^ ].

A reasonable sample of how to work with BackgroundWorker is shown in my other answer:
Changes step by step to show a control[^].

您好，

您的问题尚不清楚，因此很难给出明确的答案.

如果有帮助，这是如何使用后台工作者的示例:

Hello,

Your question is a bit unclear, so it is difficult to give an definite answer.

If it helps this is an example of how you could use a background worker:

BackgroundWorker backgroundWorker;
public Form1()
{
    InitializeComponent();
    backgroundWorker = new BackgroundWorker();
    backgroundWorker.DoWork += new DoWorkEventHandler(backgroundWorker_DoWork);
    backgroundWorker.WorkerSupportsCancellation = true;
}
void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
    while (true)
    {
        // do something...
        Console.WriteLine(DateTime.Now.ToLongTimeString());
        Application.DoEvents();
    }
}
private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker.RunWorkerAsync();
}
private void button2_Click(object sender, EventArgs e)
{
    backgroundWorker.CancelAsync();
}

显然，还有其他方法可以做到这一点.

希望对您有所帮助，

Obviously there are other ways to do it.

Hope it helps,
