CodePudding user response:

Picture. The Image=Image. FromStream (new MemoryStream (frame) ToBytes ()));

This sentence, can let the object always occupy the picture flow:
Solution: (the following is my solution in WPF, according to oneself circumstance you solve)

Convection object to read after flow, a Clone, and then use the copy assignment interface controls:

Image Image=Image. FromFile (x.F ullName);
Image x1=(Image) (Image. The Clone ());

Image. The Dispose ();//release the original file

//after the x1, completed, to release the x1, as shown in I used in WPF
