问题描述

是否可以在C#中将位图转换为intptr?如果答案是肯定的，请告诉我解决方案，如果答案是否定的，请告诉我如何将穿刺盒加载的图像转换为intptr.

Is it possible to convert bitmap to intptr in c#? If the answer is yes, please tell me the solution and if the answer is no,please tell me how I can conert the image loaded by piocture box to intptr.

推荐答案

如果这是System.Drawing.Bitmap，请使用GetHbitmap.

同样，问题是:为什么?有可能，您想要使用纯.NET库执行的操作.另外，请仔细检查您是否真的要使用PictureBox.如果您想操纵图像，设置动画或进行交互操作，PictureBox只会吃掉一些额外的资源，但不会提供任何帮助，只会增加一些麻烦.在过去的解决方案中，我对此进行了解释，同时也解释了如何做:
如何将图像保留在PictureBox中 [ ^ ]，
图片框重新加载后会丢失图纸 [如何从旧图纸中清除面板 [ ^ ].

If this is System.Drawing.Bitmap, use GetHbitmap.

Again, the question is: why? Chances are, what you want you can do using pure .NET libraries. Also, check up carefully if you really want to use PictureBox. If you want to manipulate image, or animate or do anything interactive, PictureBox will only eat up some extra resources but won''t provide any help, will only add some hassles. I explained it, and also explained what to do instead, in my past solutions:
How to keep the image Drawn in PictureBox[^],
Picture box lose drawing after reloading[^],
How do I clear a panel from old drawing[^].
