帮我看看这个错误提示什么意思啊？？？到底哪里错了？

///conn.cs///

using System;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Web.UI;

/// <summary>
/// Summary description for conn
/// </summary>
public class FW:UserControl
{
public SqlConnection objConnection;
public SqlCommand FW(string strSQL)
{
string connectionString = ConfigurationSettings.AppSettings["SqlConStr"];
objConnection = new SqlConnection(connectionString);
SqlCommand objCommand = new SqlCommand(strSQL, objConnection);
objConnection.Open();
return objCommand;
}
public void Close()
{
objConnection.Close();
}
}

///webconfig.ascx///

<%@ Control Language="C#" Inherits="FW" Src="conn.cs"%>

<%@ Import Namespace="System.Data.SqlClient"%>

<script runat="server">
string strSQL = "select * from shop_config";
SqlCommand objCommand = FW(strSQL);
....

</script>

错误提示：
'FW': member names cannot be the same as their enclosing type

change

public SqlCommand FW(string strSQL)

===>

public SqlCommand GetCommand(string strSQL)


SqlCommand objCommand = FW(strSQL);

==>

SqlCommand objCommand = GetCommand(strSQL);

如果类中的方法成员的名称与类的名称相同的话，那么这个方法应该是所谓的“构造函数”。但构造函数是不能有返回值的，而FW有返回值，故产生错误。

就是，类必须存在构造函数
