WPF bitmap to bitmapimage using CreateBitmapSourceFromHBitmap Memory leakage, wpfbitmapimage

IntPtr f = bmp. GetHbitmap (); img. Source = System. Windows. Interop. Imaging. encode (f, IntPtr. Zero, Int32Rect. Empty, BitmapSizeOptions. FromEmptyOptions ());

If the memory is not released in time for multiple times, it will explode ~

Solution:

Use the GDI32.DLL class in windows

Usage:

First reference the system. runtime. serialation class

If the solution configuration is under Debug

Place gdi32.dll in bing \ debug

Create a class

Static class Class1 {[System. Runtime. InteropServices. DllImport ("gdi32.dll")] public static extern bool DeleteObject (IntPtr o );}

Then, after each conversion

Class1.DeleteObject (f );

Just a moment.

The memory will not explode.
