我正在尝试将带有文本的任务栏图标叠加添加到windows7应用程序图标,我确实设法添加了小叠加但无法添加文本。
是否有人知道如何将动态文本添加为任务栏图标叠加?

您只能添加Image
,因此您必须创建:
RectangleF rectF = new RectangleF(0, 0, 40, 40);
Bitmap bitmap = new Bitmap(40, 40, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
Graphics g = Graphics.FromImage(bitmap);
g.FillRectangle(System.Drawing.Brushes.White, 0, 0, 40, 40);
g.DrawString("5", new Font("Arial", 25), System.Drawing.Brushes.Black, new PointF(0, 0));
IntPtr hBitmap = bitmap.GetHbitmap();
ImageSource wpfBitmap =
Imaging.CreateBitmapSourceFromHBitmap(
hBitmap, IntPtr.Zero, Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
TaskbarItemInfo.Overlay = wpfBitmap;
