如何将位图图像放入wpf ListView

Question

This is what I have

<GridViewColumn Header="Status" >
    <GridViewColumn.CellTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <Image Source="{Binding Image}" Width="22" Height="22"/>
            </StackPanel>
        </DataTemplate>
    </GridViewColumn.CellTemplate>
</GridViewColumn>

Image is a System.Drawing.Bitmap image that I am getting from a Namespace.Resources.

I cannot get any image to show up in column no matter what I try.

You need to convert from the System.Drawing.Bitmap into an ImageSource, which is what WPF uses for images. You can do this via Imaging.CreateBitmapSourceFromHBitmap :

// Include, in your class or elsewhere:
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
private static extern bool DeleteObject(IntPtr hObject);

Bitmap image = LoadYourBitmap();

IntPtr hbitmap = image.GetHbitmap();
try
{
   var bitmapSource = Imaging.CreateBitmapSourceFromHBitmap(
      hbitmap, IntPtr.Zero, Int32Rect.Empty,
      Imaging.BitmapSizeOptions.FromEmptyOptions());
}
finally
{
    // Clean up the bitmap data
    DeleteObject(hbitmap);
}
