c#WPF循环遍历控件进⾏绑定数据当wpf界⾯上有很多控件需要绑定值的时候，新新⼿⼀般是 =ng()；对于没有接触过MVVM的⼈来说，ViewModel还是有点学习成本的，下⾯的⽅法是我以前项⽬上所使⽤的，这⾥记录下，也⽅便⾃⼰以后再次使⽤，废话不多说，直接上代码，肯定有很多不好的地⽅，因为我也是新⼿，请指教，谢谢前端 　请注意，StackPanel 为布局控件，当然其他的布局控件也是可以的，x:Name命名没有啥要求，但是，控件的 X:Name命名⼀定要注意，以控件缩写加下划线再加DTO⾥的字段，否则后⾯绑定不上。后台ic class TestDTO: BaseDTO{ public string One { get; set; } public Boolean Two { get; set; } public DateTime Three { get; set; } public int Four { get; set; }}TestDTO dTO = new TestDTO { One = "one_TextBlock", Two = false, Three = , Four = 4 }; (dTO, _en);要继承由于没有连接数据库，所有数据都是直接测试数据，Fill⽅法就可以将TestDTO中的数据绑定到界⾯上了　如下： public int Index { get; set; } public int PageSize { get; set; } public override string ToString() { JsonSerializerSettings settings = new JsonSerializerSettings(); tSettings = new Func(() => { //rmatHandling = oftDateFormat; rmatString = "yyyy-MM-dd HH:mm"; ting = ed; //空值处理 lueHandling = ; return settings; }); return izeObject(this); }　要引⼊ using ; ///

"" : JResult[e("cbx_", )]; } else { ($"数据集中没有[{e("cbx_", )}]字段,⽆法填充"); } } } }这⾥⾯才是重头戏，主要的作⽤就是将控件进⾏封装，依据控件的Name来处理控件并进⾏绑定数据
