16진수 색상 문자열을 Silverlight에서 Color로 변환

1, 새 정적 클래스 ColorRevert.cs, 코드는 다음과 같습니다.

using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace Demo
{
    public static class ColorRevert
    {
        #region     
        public static Color ToColor(this　string colorName)
        {
            if (colorName.StartsWith("#"))
                colorName = colorName.Replace("#", string.Empty);
            int v = int.Parse(colorName, System.Globalization.NumberStyles.HexNumber);
            return new Color()
            {
                A = Convert.ToByte((v >> 24) & 255),
                R = Convert.ToByte((v >> 16) & 255),
                G = Convert.ToByte((v >> 8) & 255),
                B = Convert.ToByte((v >> 0) & 255)
            };
        }

        public static int ToArgb(this　Color color)
        {
            int argb = color.A << 24;
            argb += color.R << 16;
            argb += color.G << 8;
            argb += color.B;
            return argb;
        }
        #endregion
    }
}

2、Silverlight 사용자 컨트롤을 새로 만들고 Rectange 컨트롤을 추가하여 그 값에 색을 채웁니다(물론 이 값도 데이터베이스나 파라미터 등을 통해Silverlight에 전달하여 사용할 수 있습니다)
