Private Sub 生成桌面图标（消息数量 As Integer)
        Try
            Dim B As New Bitmap(My.Resources.ICO)
            Using G As Graphics = Graphics.FromImage(B)
                G.Clip = New Region(New RectangleF(0, 0, B.Width, B.Height))
                Dim Cnt As String = If(消息数量 > 999, "999+", 消息数量)
                Dim Ft As Font = New Font("黑体", 24, FontStyle.Bold)
                Dim Sz As Size = DSAPI.图形图像.获取绘制文字所需大小(Cnt, Ft)
                Using Tb As Bitmap = DSAPI.图形图像.绘制圆角矩形(Sz + New Drawing.Size(6, 4), 8, Color.Red, Color.DarkRed, Color.Transparent)
                    G.DrawImage(Tb, New Rectangle(B.Width - Tb.Width, 0, Tb.Width, Tb.Height), New Rectangle(0, 0, Tb.Width, Tb.Height), GraphicsUnit.Pixel)
                    G.TextRenderingHint = Drawing.Text.TextRenderingHint.AntiAlias
                    G.DrawString(Cnt, Ft, Brushes.White, New Point(B.Width - Tb.Width + 6, 0))
                End Using
