我发现***的解决方案是老式 Windows API:
I have found the best solution to be just old-school Windows API:
Private Sub DrawRoundRect(ByVal g As Graphics, ByVal r As Rectangle)
Dim hDC As IntPtr = g.GetHdc
Dim hPen As IntPtr = CreatePen(PS_SOLID, 0, ColorTranslator.ToWin32(Color.Red))
Dim hOldPen As IntPtr = SelectObject(hDC, hPen)
SelectObject(hDC, GetStockObject(NULL_BRUSH))
RoundRect(hDC, r.Left, r.Top, r.Right - 1, r.Bottom - 1, 12, 12)
SelectObject(hDC, hOldPen)
DeleteObject(hPen)
g.ReleaseHdc(hDC)
End Sub
这产生了我一直在寻找的对称圆角矩形:
This produces the symmetrical rounded rectangle I've been looking for:
