问题说明
我正在使用以下代码来调用应用程序中主UI线程上的控件.我的状态栏中的进度栏没有InvokeRequired，我需要以某种方式调用System.Windows.Forms.ToolStripProgressBar.
I am using the following code to invoke the controls that are on the main UI thread in my application. The progress bar that I have in my Status Strip does not have a InvokeRequired, I need to somehow invoke the System.Windows.Forms.ToolStripProgressBar.
if (txtbox1.InvokeRequired)
{
txtbox1.Invoke(new MethodInvoker(delegate { txtbox1.Text = string.Empty; }));
}正确答案

自己找到了.
Found it myself.
System.Windows.Forms.ToolStripProgressBarprgBarMain.GetCurrentParent().InvokeRequiredSevak是正确的！如果控件没有控件，则可以始终使用父控件的"InvokeRequired".
或者，您始终可以使用PInvoke检查当前线程是否与主线程不同.如果线程不同，则无需使用Invoke.如果您愿意，我可以共享该代码.
希望对您有所帮助！
Sevak is right! You can always use parent''s "InvokeRequired" if the control doesn''t have one...
Alternately you can always check if the current thread is different from the main thread using PInvoke. If the threads are different you need to use Invoke else not. If you want I can share the code for that.
Hope that helps!
