用Invoke解决跨线程操作无效问题

Error: "Cross-thread operation not valid: Control 'FileDownloaderForm' accessed from a thread other than the thread it was created on." in string: Error", MessageBoxButtons.OK, MessageBoxIcon.Error);"

从非控件创建线程之外线程访问控件时，报错：跨线程操作无效。字符串:"MessageBoxButtons.OK, MessageBoxIcon.Error);"
public static void Publish(Exception ex)
{
IWin32Window owner = null;
if(downloaderForm != null && downloaderForm.Visible)
owner = downloaderForm;
MessageBox.Show(downloaderForm, ex.ToString(), "Download Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
downloaderForm.status = DownloadStatus.Failed;
downloaderForm.canceled = true;
downloaderForm.btnCancel.Text = "&Close";
downloaderForm.btnPause.Visible = false;
}

Use CheckForIllegalCrossThreadCalls = false;

使用CheckForIllegalCrossThreadCalls = false;

Add a class level delegate to the FileDownloadForm like this:

添加一个类级别委托给FileDownloadForm，像这样的:

delegate void PublishEventHandler(Exception ex);

On the FileDownloadForm, whenever you publish an exception you should check to see if an invoke is required:

在FileDownloadForm中,每当你发布一个异常，你应该检查是否需要invoke:
catch(Exception ex)
{
if(this.InvokeRequired)
{
this.Invoke(new PublishEventHandler(ExceptionManager.Publish),
new object[]{ex});
}
else
ExceptionManager.Publish(ex);
}

There are several other ways to implement this, but basically that'll fix it.

还有其他几种方法来实现这一点,但是这个方法基本上就能解决它。
