ArcEngine颜色可视化

AE中利用.NET中的ColorDialog对话框，将color对象转化为ArcEngine中的IRgbColor

（1）在实现颜色选择之前，需定义这两种颜色之间的转换函数

     //Color转换为Rgbcolor

 private IRgbColor GetIRgbcolor()
        {
            ColorDialog pColorDialog = new ColorDialog();
            if (pColorDialog.ShowDialog() == DialogResult.OK)
            {
                return ConvertColorToIRgbcolor(pColorDialog.Color);
            }
            else
            {
                return null;
            }

 
        }
        private Color ConvertIRgbColorToColor(IRgbColor pRgbcolor)
        {

            return ColorTranslator.FromOle(pRgbcolor.RGB);
        }
        private IRgbColor ConvertColorToIRgbcolor(Color pColor)
        {
           IRgbColor pRgbcolor=new RgbColorClass();
            pRgbcolor.RGB=pColor.R+pColor.G*256+pColor.B*65536;

            return pRgbcolor;
        }
