ASP中<% %>=@

語法規則

Razor 程式碼封裝於 @{ ... } 中

行內表示式（變數和函式）以 @ 開頭

程式碼語句以分號結尾

字串由引號包圍

C# 程式碼對大小寫敏感

C# 檔案的副檔名是 .cshtml

@{ var name = "Word!!!!";}
@for (int i = 0; i < 3; i++)
{
<h1>Hello @name</h1>
}
@if (true)
{
<h1>Hello @name</h1>
}

Public ActionResult Loop()
{
     //ViewBag是動態型別
     ViewBag.Loop=new List<string>{"張三","李四","王五"};
     return View();
}
 


例子
public ActionResult Index()
 {
 TestObjectService();

 using (RazorDemo.Models.MySchoolEntities entities = new Models.MySchoolEntities())
 {
 return View(entities.Students.ToList());
 }
 return View();
 
 }

 public ActionResult Test()
 {
 return View();
 }

 public void TestEntityClient()
 {
 using (EntityConnection conn = new EntityConnection("name=MySchoolEntities"))
 {
 conn.Open();
 EntityCommand cmd = conn.CreateCommand();
 cmd.CommandText = @"SELECT VALUE c FROM MySchoolEntities.Students AS c WHERE c.StudentNo = 23214";
 EntityDataReader rdr = cmd.ExecuteReader(CommandBehavior.SequentialAccess);
 while (rdr.Read())
 Console.WriteLine(rdr[2].ToString());
 rdr.Close();
 }
 
 }


 public void TestObjectService()
 {
 using (ObjectContext context = new ObjectContext(("name=MySchoolEntities")))
 {
 string eSql = "SELECT VALUE c FROM MySchoolEntities.Students AS c";
 ObjectQuery<Student> query = context.CreateQuery<Student>(eSql);
 foreach (Student stu in query.ToList())
 {
 Console.WriteLine(stu.StudentName);//輸出學生姓名
 }
 }
 }
前臺：
@foreach (var item in Model) {
 <tr>
 <td>
 @Html.DisplayFor(modelItem => item.StudentNo)
 </td>

 <td>
 @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
 @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
 @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
 </td>
 </tr>
}
