从控制器传递多个Model到视图，可以通过ViewData, ViewBag, PartialView, TempData, ViewModel，Tuple等，本篇逐一体验。本篇源码在github。

 

在视图页面，下拉框选择课程触发事件，分别显示老师课程表、学生上课表，如图：

 

相关的Model：

    public class Course
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
 
    public class Teacher
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public List<Course> Courses { get; set; }
    }
 
    public class Student
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public List<Course> Courses { get; set; }
    }

@Html.Raw(Json.Encode(ViewData["Students"]))是把Model转换成json字符串，需要用到System.Web.Helpers，把此类库引用到项目，并且必须设置"复制到本地属性"为true,否则报错。

 

  使用ViewBag传递多个Model

□ HomeController

            ViewBag.Students = _repository.GetStudents();
            ViewBag.Teachers = _repository.GetTeachers();
            return View();
        }

□ Home/ViewBagDemo.cshtml

下拉框遍历课程改成：

@foreach (var course in ViewBag.Courses)     

 

getTeacherTable()方法中改成：

var teachers = @Html.Raw(Json.Encode(ViewBag.Teachers));

 

getStudentTable()方法中改成：

var students = @Html.Raw(Json.Encode(ViewBag.Students));
