将正常的ProgressBar放置到ToolStripProgressBar的确切位置

Question

在C＃或VBNET中如何在运行时将正常的ProgressBar控件（或第三方ProgressBar）放置到statusstrip中ToolStripProgressBar的确切位置？

我试过这个，但正常的进度条移动到左上角，我的statusstrip在底部...：

ProgressBar1.Size = ToolStripProgressBar1.ProgressBar.Size
ProgressBar1.Location = ToolStripProgressBar1.ProgressBar.Location

而其他事情也发生了同样的事情：

ProgressBar1.Size = ToolStripProgressBar1.ProgressBar.Bounds.Size
ProgressBar1.Location = ToolStripProgressBar1.ProgressBar.Bounds.Location

有了这个，正常的进度条移动到statusstrip的底角但是大小/位置不准确，我可以看到正常进度条的ToolStripProgressBar1：

ProgressBar1.Size = ToolStripProgressBar1.ProgressBar.Bounds.Size
ProgressBar1.Location = ToolStripProgressBar1.ProgressBar.Parent.Bounds.Location

我不知道你为什么要放置一个控件来覆盖现有的ToolStripProgressBar ，但幸运的是，实现这样的事情很简单。 您可以直接访问托管ProgressBar通过ProgressBar属性，使用PointToScreen正确的方法来获取屏幕坐标的位置ProgressBar ，然后再转换到位置的形式协调版本，并使用你的另一进度。 请注意，您在外面使用的ProgressBar应该将Parent设置为您的表单：

public Form1(){
  InitializeComponent();
  //handle the Shown event of your form to ensure
  //your toolStripProgressBar1 has been rendered correctly with correct location
  Shown += (s,e) => {
    //suppose you have a progressbar called progressBar1
    progressBar1.Location = PointToClient(toolStripProgressBar1.ProgressBar
                                               .PointToScreen(Point.Empty));
    //do this to cover the whole existing toolStripProgressBar1 exactly
    progressBar1.Size = toolStripProgressBar1.ProgressBar.Size;
    //call this to ensure your progressBar1 lies on top of all other controls of 
    //your form (of course your statusStrip should be a control of your form)
    progressBar1.BringToFront();
  }; 
  //We should also handle the SizeChanged event of the form
  //because when resizing, the location of the toolStripProgressBar (relatively
  // to the form) will change
  SizeChanged += (s, e) => {
    progressBar1.Location = PointToClient(toolStripProgressBar1.ProgressBar
                                                .PointToScreen(Point.Empty));
  };
}
