将InteropBitmap转换为BitmapImage [英] InteropBitmap to BitmapImage

问题描述

我正在尝试将 Bitmap(SystemIcons.Question)转换为 BitmapImage ，以便可以在WPF Image控件中使用它.

I'm trying to Convert a Bitmap (SystemIcons.Question) to a BitmapImage so I can use it in a WPF Image control.

我有以下方法将其转换为 BitmapSource ，但它返回 InteropBitmapImage ，现在的问题是如何将其转换为 BitmapImage .直接投射似乎无效.

I have the following method to convert it to a BitmapSource, but it returns an InteropBitmapImage, now the problem is how to convert it to a BitmapImage. A direct cast does not seem to work.

有人知道怎么做吗?

代码:

 public BitmapSource ConvertToBitmapSource()
        {
            int width = SystemIcons.Question.Width;
            int height = SystemIcons.Question.Height;
            object a = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(SystemIcons.Question.ToBitmap().GetHbitmap(), IntPtr.Zero, System.Windows.Int32Rect.Empty, BitmapSizeOptions.FromWidthAndHeight(width, height));

            return (BitmapSource)a;
        }

返回BitmapImage的属性:(绑定到我的图像控件)

property to return BitmapImage: (Bound to my Image Control)

public BitmapImage QuestionIcon
        {
            get
            {
                return  (BitmapImage)ConvertToBitmapSource();
            }
        }

推荐答案

InteropBitmapImage 继承自 ImageSource ，因此您可以直接在 Image 控件.您不需要将其作为 BitmapImage .

InteropBitmapImage inherits from ImageSource, so you can use it directly in an Image control. You don't need it to be a BitmapImage.
