代碼

Private Sub 生成桌面圖標（消息數量 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(消息數量 > 999, "999+", 消息數量)
                Dim Ft As Font = New Font("黑體", 24, FontStyle.Bold)
                Dim Sz As Size = DSAPI.圖形圖像.獲取繪製文字所需大小(Cnt, Ft)
                Using Tb As Bitmap = DSAPI.圖形圖像.繪製圓角矩形(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
            End Using

            Dim Stm As New IO.MemoryStream
            DSAPI.圖形圖像.圖像生成ICO圖標(B, 128).Save(Stm)
            IO.File.WriteAllBytes("c:\tmp.ico", Stm.ToArray)
            Stm.Close()
