最简单的方法是直接从文件中生成WPF位图。

否则你将不得不使用system . windows . interop . image . createbitmapsourcefromhbitmap。

// at class level;
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);    // https://stackoverflow.com/a/1546121/194717


/// <summary> 
/// Converts a <see cref="System.Drawing.Bitmap"/> into a WPF <see cref="BitmapSource"/>. 
/// </summary> 
/// <remarks>Uses GDI to do the conversion. Hence the call to the marshalled DeleteObject.

/// <param name="source">The source bitmap.</param> 
/// <returns>A BitmapSource</returns> 
public static System.Windows.Media.Imaging.BitmapSource ToBitmapSource(this System.Drawing.Bitmap source)
{
    var hBitmap = source.GetHbitmap();
    var result = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, System.Windows.Int32Rect.Empty, System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());

    DeleteObject(hBitmap);

    return result;
}

我在一家图像供应商工作，写了一个WPF到我们的图像格式的适配器，它类似于System.Drawing.Bitmap。

我写了这个KB来向我们的客户解释:

http://www.atalasoft.com/kb/article.aspx?id=10156

这里有代码可以做到这一点。你需要用Bitmap替换AtalaImage，并做与我们正在做的相同的事情——这应该是相当简单的。

我来到这个问题，因为我试图做同样的事情，但在我的情况下，位图是来自资源/文件。我发现最好的解决方案如下所示:

http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmapimage.aspx

// Create the image element.
Image simpleImage = new Image();    
simpleImage.Width = 200;
simpleImage.Margin = new Thickness(5);

// Create source.
BitmapImage bi = new BitmapImage();
// BitmapImage.UriSource must be in a BeginInit/EndInit block.
bi.BeginInit();
bi.UriSource = new Uri(@"/sampleImages/cherries_larger.jpg",UriKind.RelativeOrAbsolute);
bi.EndInit();
// Set the image source.
simpleImage.Source = bi;
