我们如何在asp.net的网格视图中显示数据？

Question

当我尝试从Sql server数据库获取数据并在GridView中显示时，我得到了以下内容。我的代码如下：

string connstr = @"Data Source=.\SQLEXPRESS; Initial Catalog=Aman;User ID=sa; Password=123";
        DataSet ds = new DataSet();
        SqlDataAdapter da;
        DataTable dt = new DataTable();

        SqlConnection conn = new SqlConnection(connstr);
        conn.Open();
        da = null;
        string strsql = "Select File_ID,File_Name,File_Type from Upload_file";
        da = new SqlDataAdapter(strsql, conn);
        da.Fill(ds, "Upload_file");

        GridView1.DataSource = ds.Tables["Upload_file"].DefaultView;
        GridView1.DataBind();

要在视图的网格视图中显示数据，请执行以下操作（ASP.Net MVC razor）：

<table>
<tr>
<td>
Heading
</td>
</tr>

@foreach(var item in Model)
{
<tr>
<td>
@* Something that you want to display *@
</td>
</tr>
}

</table>

如果要对检索到的数据执行特定操作，则应在rowdatabinding / celldatabinding事件中执行此操作，否则应定义列或在标记中或通过代码隐藏 http://msdn.microsoft.com/en-us/library/aa479342.aspx

试试这个

           string connstr = @"Data Source=.\SQLEXPRESS; Initial Catalog=Aman;User ID=sa; Password=123";
           SqlConnection conn = new SqlConnection(connstr);
           conn.Open();
           SqlDataAdapter adapter = new SqlDataAdapter("Select File_ID,File_Name,File_Type from Upload_file ", conn);
           DataTable dt = new DataTable();
           adapter.Fill(dt);
           conn.Close();
           GridView1.DataSource = dt;

           GridView1.DataBind();

希望这会有所帮助

最简单的方法可能是：

//Create sql DATA source by passing connection string and select command
SqlDataSource mySqlDataSource= new SqlDataSource("Data Source=.\SQLEXPRESS; Initial Catalog=Aman;User ID=sa; Password=123", "Select File_ID,File_Name,File_Type from Upload_file");

//Assign the data source to GridView data source
GridView1.DataSource = mySqlDataSource;
//Do data binding
GridView1.DataBind();
