wpf MVVM的简单绑定

1.前台部分：绑定用Bing

 <TextBox Text="{Binding MyString}" Width="300" Height="30" VerticalContentAlignment="Center"></TextBox>

3.在ViewModel 写属性

 #region 属性
        private string myString;

        public string MyString
        {
            get { return myString; }
            set
            {
                myString = value;
                this.RaisePropertyChanged("MyString");
            }
        }
        #endregion


        #region 构造函数
        public MainWindowViewModels()
        {
            MyString = "Hollo Word";
        }

属性快捷方法:propn + 2次Tab

构造函数快捷方法：ctor +Tab

4.在后台实例化下ViewModel

this.DataContext = new MainWindowViewModels();

5.运行结果
