在WPF 中将一个现成的 Bitmap 位图转换成 ImageSource 用于显示一个麻烦的事儿,因为 WPF 并没有提供多少可以转过来的方法。不过产生 Bitmap 来源却非常多,比如屏幕截图、GDI 图、数组或其它非托管框架生成的图片。 WPF 官方提供了一种方法,使用System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap()方法...

阿圖片怎麼顯示不出來了』，這個部分請參考一下Convert memory stream to BitmapImage? 必須要指定CacheOption的屬性，強制在載入的時候去讀取，才會確保顯示的正常；不然如果需要載入的時候，memorystream已經被釋放掉了，就會造成上面說的圖片無法顯示的狀況了。稍加修改之後，程式碼會像是這樣 System.IO....
