一，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 Courses { get; set; } } public class Student { public int Id { get; set; } public string Name { get; set; } public List Courses { get; set; } } 二，使用ViewData传递多个Model
HomeController public ActionResult Index() { ViewData["Courses"] = _repository.GetCourses(); ViewData["Students"] = _repository.GetStudents(); ViewData["Teachers"] = _repository.GetTeachers(); return View(); } Home/Index.cshtml@using MvcApplication1.Models@using System.Web.Helpers;@{ Layout = null;} ViewDataDemo 选择课程
老师课程表
学生上课表
三，使用ViewBag传递多个Model
HomeController public ActionResult ViewBagDemo() { ViewBag.Courses = _repository.GetCourses(); 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));@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。 四，使用部分视图传递多个Model
HomeController public ActionResult PartialViewDemo() { List courses = _repository.GetCourses(); return View(courses); } public ActionResult StudentsToPVDemo(string courseName) { IEnumerable courses = _repository.GetCourses(); var selectedCourseId = (from c in courses where c.Name == courseName select c.Id).FirstOrDefault(); IEnumerable students = _repository.GetStudents(); var studentsInCourse = students.Where(s => s.Courses.Any(c => c.Id == selectedCourseId)).ToList(); return PartialView("StudentPV", studentsInCourse); } public ActionResult TeachersToPVDemo(string courseName) { IEnumerable courses = _repository.GetCourses(); var selectedCourseId = (from c in courses where c.Name == courseName select c.Id).FirstOrDefault(); IEnumerable teachers = _repository.GetTeachers(); var teachersForCourse = teachers.Where(t => t.Courses.Any(c => c.Id == selectedCourseId)).ToList(); return PartialView("TeacherPV", teachersForCourse); } Home/PartialViewDemo.cshmtl@model IEnumerable @{ Layout = null;} PatialViewDemo 选择课程
老师课程表
学生上课表
TeacherPV.cshtml与StudentPV.cshtml
@model IEnumerable
编号
名称
@foreach (var item in Model)
{ @item.Id
@item.Name
}
五， 使用TempData传递多个Model
HomeController public ActionResult TempDataDemo() { //第一次从数据库读取数据放到TempData中，以后的请求从TempData中获取数据 TempData["Courses"] = _repository.GetCourses(); //让TempData保存数据，直到下一次请求 TempData.Keep("Courses"); return View(); } public ActionResult TeachersTempData(string courseName) { var courses = TempData["Courses"] as IEnumerable ; //由于TempData["Courses"]还要被下一次请求，继续TempData保存数据 TempData.Keep("Courses"); var selectedCourseId = (from c in courses where c.Name == courseName select c.Id).FirstOrDefault(); IEnumerable teachers = _repository.GetTeachers(); var teachersForCourse = teachers.Where(t => t.Courses.Any(c => c.Id == selectedCourseId)).ToList(); return PartialView("TeacherPV", teachersForCourse); } public ActionResult StudentsTempData(string courseName) { var courses = TempData["Courses"] as IEnumerable ; //由于TempData["Courses"]还要被下一次请求，继续TempData保存数据 TempData.Keep("Courses"); var selectedCourseId = (from c in courses where c.Name == courseName select c.Id).FirstOrDefault(); IEnumerable students = _repository.GetStudents(); var studentsForCourse = students.Where(s => s.Courses.Any(c => c.Id == selectedCourseId)).ToList(); return PartialView("StudentPV", studentsForCourse); }Home/TempDataDemo.cshtml下拉框遍历课程： @foreach (var course in Model) ajax请求老师课程表： @Url.Action("TeachersTempData","Home") ajax请求学生上课表： @Url.Action("StudentsTempData","Home") 六，使用ViewModel传递多个Model
View Model public class SchoolVm { public List Courses { get; set; } public List Students { get; set; } public List Teachers { get; set; } } □ HomeController public ActionResult ViewModelDemoVM() { SchoolVm vm = new SchoolVm(); vm.Courses = _repository.GetCourses(); vm.Teachers = _repository.GetTeachers(); vm.Students = _repository.GetStudents(); return View(vm); } □ Home/ViewModelDemoVM.cshtml@model MvcApplication1.Models.SchoolVm下拉框遍历课程： @foreach (var course in Model.Courses) ajax请求老师课程表和学生上课表： @Html.Raw(Json.Encode(Model.Teachers)) @Html.Raw(Json.Encode(Model.Students))
