如何將位圖圖像放入wpf ListView

Question

這就是我所擁有的

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

圖像是從Namespace.Resources獲取的System.Drawing.Bitmap圖像。

無論我如何嘗試，都無法在列中顯示任何圖像。

您需要從System.Drawing.Bitmap轉換為ImageSource，這是WPF用於圖像的。 您可以通過Imaging.CreateBitmapSourceFromHBitmap來執行此操作 ：

// 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);
}
