C# 在BackgroundWorker完成之前禁用PictureBoxes和/或更简单的方法

Application.DoEvents（）。这将清除该处理程序运行时发生的所有挂起的单击事件，并在方法退出后阻止它们运行：
private void Picture_Click(object sender, EventArgs e) //Function with two parameters passed in.
{
// ... all of your previous code ...
Application.DoEvents(); // flush the queue before leaving this event
}
请注意，要使其正常工作，需要禁用标签，然后在重新启用它之前调用DoEvents（）。下面是一个简单的例子来说明区别：
private int Number_of_Images;
private void label1_Click(object sender, EventArgs e)
{
label1.Enabled = false;
Number_of_Images++;
label1.Text = "Clicks: " + Number_of_Images.ToString();
System.Threading.Thread.Sleep(3000);
label1.Enabled = true;
}
private void label2_Click(object sender, EventArgs e)
{
label2.Enabled = false;
Number_of_Images++;
label2.Text = "Clicks: " + Number_of_Images.ToString();
System.Threading.Thread.Sleep(3000);
Application.DoEvents();
label2.Enabled = true;
}
单击label1/label2，然后在同一个被禁用时再单击几次以查看差异。IMHO，没有正确的答案会建议调用Application.DoEvents（）
。很容易将隐藏的重入引入到非为其设计的代码中，导致许多微妙的、难以修复的错误
