十六進位顏色字串轉換成Color在Silverlight中的實現

1、建立一個靜態類ColorRevert.cs,代碼如下：

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 色彩轉換        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、 建立一個Silverlight使用者控制項，並添加一個Rectange控制項，並為其賦值填充顏色(當然這個值也可以通過資料庫或參數等傳遞到Silverlight中並使用)

<UserControl x:Class="Demo.MainPage"    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"    >    <Grid x:Name="LayoutRoot" Background="White">        <Rectangle Height="100" HorizontalAlignment="Left" Margin="306,221,0,0" Name="rectangle1" Stroke="Black" StrokeThickness="1" VerticalAlignment="Top" Width="241" />    </Grid></UserControl>using System;using System.Collections.Generic;using System.Linq;using System.Net;using System.Windows;using System.Windows.Controls;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Animation;using System.Windows.Shapes;using System.Json;using ESRI.ArcGIS.Client.Bing;using ESRI.ArcGIS.Client;using ESRI.ArcGIS.Client.Geometry;using System.Windows.Media.Imaging;namespace Demo{    public partial class MainPage : UserControl    {        public MainPage()        {            InitializeComponent();            SolidColorBrush scb = new SolidColorBrush();            scb.Color = "#FFBBCCFF".ToColor();  //核心代碼在這裡            rectangle1.Fill = scb;        }    }}
