C#中使用 Lazy＜T＞在WPF中实现单例模式

Lazy是延迟对象，通过它可以延迟创建T对象，也就是说，虽然已经声明了对象，但是实际上只有在使用T对象的时候，才会去创建这个对象。

在WPF中, 公共方法 可以写在单独的一个类中, 各个viewmodel等需要的时候再去使用Lazy调用.

例如
建立公共类appData

using GalaSoft.MvvmLight;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using DAL;

namespace ShenhuaSQLite
{
    public class AppData: ObservableObject
    {
        public AppData()
        {

        }

        public static AppData Instance = new Lazy<AppData>(() => new AppData()).Value;

        private string systemName = "Zg上位机测试";

        public string SystemName
        {
            get { return systemName; }
            set { systemName = value; }
        }

        private SysAdmins sysAdmins = new SysAdmins();

        public SysAdmins CurrentUser
        {
            get { return sysAdmins; }
            set { sysAdmins = value;  RaisePropertyChanged(); }
        }

        /// 

        /// 主窗体
        /// 
        public MainWindow MainWindow { get; set; } = null;

        /// 

        /// 显示或隐藏遮罩层
        /// 
        /// 
        public void ShowMarkLayer(bool isMark)
        {
            if (MainWindow == null) return;
            //MainWindow.markLayer.Visibility = isMark ? System.Windows.Visibility.Visible : System.Windows.Visibility.Hidden;
        }

    }
}

在登录窗体中, 可以在构造函数中实例化lazy, 实现调用appData中所有属性和方法. 这有些类似于博途中的多重背景数据块.
