Compilation error in asp.net page
I am getting this message in my asp.net page.
Any suggestions to resolve this will be greatly appreciated. Thx.
Compilation Error 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: ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).
Source Error:
Line 1: using System;
Line 2: using System.Data;
Line 3: using System.Data.SqlClient;
The aspx code is:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
</form>
</body>
</html>
The C# code is:
using System;
using System.Data;
using System.Data.SqlClient;
class SqlConnectionDemo
{
static void Main()
{
SqlConnection conn = SqlConnection("Data Source=(local); Initial Catalog=JobSearchManager;Integrated Security = SSPI");
SqlDataReader rdr = null;
try
{
conn.Open();
SqlCommand cmd = new SqlCommand("select * from Agency", conn);
rdr = cmd.ExecuteReader;
while (rdr.Read())
{
Console.WriteLine(rdr[0]);
}
}
finally
{
if (rdr != null)
{
rdr.Close();
}
if (conn != null)
{
conn.Close;
}
}
}
}
Your aspx code says Inherits="_Default" but your class is called SqlConnectionDemo. These need to match.
Your C# code is not the code behind for that web page (or any web page). It should have something like this at the beginning of the class:
class _Default : System.Web.Page {
Your class has a Main method, as if it was from a console application instead. Have you pasted a database example over the original code behind class?
Do you have a class file named "Default.aspx.cs" that looks like this?
using System;
namespace YourApplicationName
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
加载中,请稍侯......
