C＃/ WPF：对剪贴板进行任何更改时触发的任何事件？ [英] C#/WPF: Any event that triggers when any changes are made to clipboard?

问题描述

我想要的最终结果是实际上检测剪贴板是否包含任何图像，如果是，则设置一个图像控件以显示该图像。我在想如果剪贴板包含图像，我将需要一种监控剪贴板的方法。我该如何实现？我认为可能没有此类事件，所以也许我要定期检查剪贴板以查看是否包含任何图像（如果显示的话）？

The final outcome I want is actually detect if the clipboard contains any Image, if so then set a Image control to display that image. I am thinking I will need a way to monitor the clipboard if it contains an Image. How can I achieve this? I am thinking probably theres no such event so maybe i check the clipboard at regular intervals to see if it contains any image if so display it? Will it be very inefficient?

更新

我想知道是否一样吗？剪贴板中包含图像时启用/禁用我的按钮的机制可以在这里使用吗？我正在使用 MVVM Foundation 。

I am wondering if the same mechanism that enables/disables my button when the clipboard contains an image can come into use here? I am using MVVM Foundation.

GetImageFromClipboard = new RelayCommand(() => ImageData = Clipboard.GetImage(), () => Clipboard.ContainsImage() );

因为它正确启用/禁用了绑定到此按钮的按钮。我可以做类似CanExecute更改时的操作，如果有图像，则显示它吗？

because it enables/disables my Button bound to that correctly. Can i do something like when the CanExecute changes, If theres an image, display it?
