推荐答案

要变通解决此问题，请确保实例化线程在STA中运行.
如果使用MTAThread属性指定主机应用程序的主线程在MTA中运行，则必须改用STAThread属性.为此，将"MTAThread"代码替换为以下代码:

To work around this problem, make sure that the instantiating thread runs in an STA.

If you use the MTAThread attribute to specify that the main thread of the host application runs in an MTA,you must use the STAThread attribute instead. To do this, replace the code of ''MTAThread'' with the following code:

<STAThread()> _
