推荐答案

您可以执行此操作在WPF中. MSDN上有一个有关如何实现颜色选择器的示例:您可以从此处 http://msdn下载.microsoft.com/en-us/library/ms771620.aspx

要构建圆形，可以使用现成的Ellipse类: http://msdn.microsoft.com/zh-CN/library/system.windows.shapes.ellipse.aspx

For building the circle, you can use the out of the box Ellipse class: http://msdn.microsoft.com/en-us/library/system.windows.shapes.ellipse.aspx

对于旋转，您可以在圆上使用RotateTransform: http://msdn.microsoft.com/en-us/library/system.windows.media.rotatetransform.aspx

And for rotating you can use a RotateTransform on the circle: http://msdn.microsoft.com/en-us/library/system.windows.media.rotatetransform.aspx
