Asp.net mvc 如何使用ViewBag MVC在视图中绑定Linq多个模型数据？
我正在使用Asp.net mvc 如何使用ViewBag MVC在视图中绑定Linq多个模型数据？,asp.net-mvc,linq,asp.net-mvc-4,viewbag,Asp.net Mvc,Linq,Asp.net Mvc 4,Viewbag,我正在使用LINQ连接多个模型类，并使用ViewBag将LINQ对象传递到View 我在重复数据或绑定数据时遇到问题 模型属性： public class SalesModel { public string CustomerName { get; set; } public int SSN { get; set; } public int LicenseId { get; set; } public int Age { get; set; } publi
