1。首先创建一个模式将保存记录的值。例如：

 公共类学生
 {
公共字符串名字{获得;设置;} 
公共字符串名字{获得;设置;} 
公共字符串类{获取;集;} 
 .... 
} 
 

2。然后从你的读者的行装载到一个列表或东西：

 公众的ActionResult学生（）
 {
字符串的connectionString =<保证连接字符串HERE>中; 
字符串SQL =SELECT * FROM学生; 
的SqlCommand CMD =新的SqlCommand（SQL，conn）;在使用（SqlConnection的康恩=新的SqlConnection（的connectionString））
 {
 conn.Open（）

; 
 SqlDataReader的RDR = cmd.ExecuteReader（）; 
 VAR模型=新的List&LT;的Student GT;（）; 
，而（rdr.Read（））
 {
变种学生=新学生（）; 
 student.FirstName = RDR [名字]; 
 student.LastName = RDR [姓氏]; 
 student.Class = RDR [类]; 
 .... 

 model.Add（学生）; 
} 

} 

返回查看（模型）; 
} 
 

3。最后在你的查看，声明的那种模型的：

  @model名单<的Student GT; 

< H1>学生< / H1> 

<表> 
< TR> 
百分位>首先名称和LT; /第i 
<第i个姓< /第i 
<第i类< /第i 
< / TR> 
 @foreach（以型号VAR学生）
 {
< TR> 
< TD> @ student.FirstName< / TD> 
< TD> @ student.LastName< / TD> 
< TD> @ student.Class< / TD> 
< / TR> 
} 
< /表> 
 

Using ASP.NET MVC with C#, how do you pass some database records to a View and display them in table form?

I need to know how I can transfer/pass some rows of records from a database that have been returned to an SqlDataReader object and pass that object to the View so I can display all the records contained by the object in the View using foreach.

The following code is what I'm I'm trying to do. But its not working.

The Controller:

public ActionResult Students()
{
    String connectionString = "<THE CONNECTION STRING HERE>";
    String sql = "SELECT * FROM students";
    SqlCommand cmd = new SqlCommand(sql, connectionString);

    using(SqlConnection connectionString = new SqlConnection(connectionString))
    {
        connectionString.Open();
        SqlDataReader rdr = cmd.ExecuteReader();
    }

    ViewData.Add("students", rdr);

    return View();
}

The View:

<h1>Student</h1>

<table>
    <!-- How do I display the records here? -->
</table>

1. First create a Model that will hold the values of the record. for instance:

public class Student
{
    public string FirstName {get;set;}
    public string LastName {get;set;}
    public string Class {get;set;}
    ....
}

2. Then load the rows from your reader to a list or something:

public ActionResult Students()
{
    String connectionString = "<THE CONNECTION STRING HERE>";
    String sql = "SELECT * FROM students";
    SqlCommand cmd = new SqlCommand(sql, conn);

    using(SqlConnection conn = new SqlConnection(connectionString))
    {
        conn.Open();
        SqlDataReader rdr = cmd.ExecuteReader();
        var model = new List<Student>();
        while(rdr.Read())
        {
            var student = new Student();
            student.FirstName = rdr["FirstName"];
            student.LastName = rdr["LastName"];
            student.Class = rdr["Class"];
            ....

            model.Add(student);
        }

    }

    return View(model);
}

3. Lastly in your View, declare the kind of your model:

@model List<Student>

<h1>Student</h1>

<table>
    <tr>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Class</th>
    </tr>
    @foreach(var student in Model)
    {
    <tr>
        <td>@student.FirstName</td>  
        <td>@student.LastName</td>  
        <td>@student.Class</td>  
    </tr>
    }
</table>
