“System.InvalidOperationException：该对象当前正在其他地方使用” - 我该如何解决？ [英] "System.InvalidOperationException: The object is currently in use elsewhere" - how do I resolve this?

问题描述

尝试更新图像时出现此错误。
这是一个跨线程更新，但是我使用了.Invoke（），所以不应该是问题，应该如何。

解决方案

（回答我自己的问题，对于其他人，以备将来参考）

em>（还不完全确定），这是因为如果控件尚未加载/显示，InvokeRequired将始终返回false。我已经做了一个解决方案，似乎现在工作，这是简单地引用相关控件在其创建者的句柄，如下所示：

 code> var x = this.Handle;

I got this error when trying to update an image. It was a cross-thread update, but I used .Invoke(), so that shouldn't be the problem, should it.

解决方案

(Answering my own question, for others, and for future reference)

I think (not yet entirely sure) that this is because InvokeRequired will always return false if the control has not yet been loaded/shown. I have done a workaround which seems to work for the moment, which is to simple reference the handle of the associated control in its creator, like so:

var x = this.Handle;
