你如何獲得一個位圖圖像到一個WPF的ListView

Question

這是我

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

圖片是我從Namespace.Resources得到一個System.Drawing.Bitmap圖像。

無論我嘗試什麼，我都無法在列中顯示任何圖像。

您需要將System.Drawing.Bitmap轉換爲ImageSource，這是WPF用於圖像的內容。您可以通過Imaging.CreateBitmapSourceFromHBitmap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); 
}
