Silverlight操作客戶端註冊表(優化)

前面貼出了Silverlight在OOB模式下操作客戶端的註冊表，後來自己又對代碼進行了優化，將其封裝成了一個操作類。

1.新建一個Silverlight類庫，命名爲ZKR.Silverlight.Core；

2.在類庫下新建類，命名爲LocalRegistryModel.cs；

3.實現代碼：

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 ZKR.Silverlight.Core
{
    /// <summary>
    /// 本地已安裝軟件的註冊表對象(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall)
    /// </summary>
    public class LocalRegistryModel
    {
        /// <summary>
        /// 註冊表名稱
        /// </summary>
        public string RegName { get; set; }
        /// <summary>
        /// 軟件名稱
        /// </summary>
        public string DisplayName { get; set; }
        /// <summary>
        /// 軟件版本
        /// </summary>
        public string DisplayVersion { get; set; }
        /// <summary>
        /// 發佈者
        /// </summary>
        public string Publisher { get; set; }
        /// <summary>
        /// 安裝目錄
        /// </summary>
        public string InstallLocation { get; set; }
        /// <summary>
        /// 安裝日期
        /// </summary>
        public string InstallDate { get; set; }
        /// <summary>
        /// 運行路徑(可能是圖標路徑)
        /// </summary>
        public string DisplayIcon { get; set; }
        /// <summary>
        /// 卸載路徑
        /// </summary>
        public string UninstallString { get; set; }

        public LocalRegistryModel()
        { }
    }
}

4.在類庫下新建類，命名爲LocalMachine.cs;
