查看错误@Foreach（VAR项目...）型号/控制器/视图

Question

Heey，

我有这似乎是一个愚蠢的问题，但我不能修复它，我不知道为什么我想我可以俯瞰所以我需要一组新的眼睛。

我有一个模型类：

namespace LaatsteStudentWebAPI.Models 
{ 
    public class Student 
    { 
     public int StudenNr { get; set; } 
     public string Naam { get; set; } 
     public string Woonplaats { get; set; } 
     public string Adres { get; set; } 
     public int TelefoonNr { get; set; } 
     public string School { get; set; } 
    } 
} 

和控制器：

namespace LaatsteStudentWebAPI.Controllers 
{ 
    public class ArticleController : Controller 
    { 
     private List<Student> students = new List<Student>(); 
     private int _nextId = 1; 
     SqlConnection con; 
     SqlDataAdapter da; 
     DataSet ds = new DataSet(); 

     public ActionResult Index() 
     { 
      SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["DefaultConnection"].ToString()); 
      da = new SqlDataAdapter("SELECT StudentNr, Naam, Woonplaats, Adres, TelefoonNr, School FROM [Table] ORDER BY StudentNr DESC", con); 
      da.Fill(ds); 
      foreach (DataRow dr in ds.Tables[0].Rows) 
      { 
       students.Add(new Student() { StudenNr = int.Parse(dr[0].ToString()), Naam = dr[1].ToString(), Woonplaats = dr[2].ToString(), Adres = dr[3].ToString(), TelefoonNr = int.Parse(dr[4].ToString()), School = dr[5].ToString() }); 
      } 
      return View(students); 

     } 
    } 
} 

和一个视图：

@model IEnumerable<LaatsteStudentWebAPI.Models.Student> 

@{ 
    ViewBag.Title = "Index"; 
} 

<h2>This is the Index</h2> 
<table> 

    <thead> 
     <tr> 
      <td>StudentNummer</td> 
      <td>Naam</td> 
      <td>Woonplaats</td> 
      <td>Adres</td> 
      <td>Telefoonnummer</td> 
      <td>School</td> 
     </tr> 
    </thead> 

@foreach (var item in LaatsteStudentWebAPI.Models.Student) 
{ 
    <tr> 
     <td>@item.StudenNr</td> 
     <td>@item.Naam</td> 
     <td>@item.Woonplaats</td> 
     <td>@item.Adres</td> 
     <td>@item.TelefoonNr</td> 
     <td>@item.School</td> 


    </tr> 

} 
</table> 

现在我的问题是，当我运行它看起来一切好吧，（我知道它的凌乱的代码，但只是希望它的工作） 但我得到这个问题/错误。

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0119: 'LaatsteStudentWebAPI.Models.Student' is a 'type', which is not valid in the given context

Line 20: 
Line 21: 
Line 22: @foreach (var item in LaatsteStudentWebAPI.Models.Student) 
Line 23: { 
Line 24:  <tr> 

正在发生的事情错了，它必须是一个小问题，我认为并希望容易解决，我希望你们不能帮我。

Answer 1

您试图通过Student循环，但您的型号为IEnumerable<Student>。尝试遍历Model：

@foreach (var item in Model) 
{ 
    <tr> 
     <td>@item.StudenNr</td> 
     <td>@item.Naam</td> 
     <td>@item.Woonplaats</td> 
     <td>@item.Adres</td> 
     <td>@item.TelefoonNr</td> 
     <td>@item.School</td>  
    </tr>  
}
