由于不起作用而无法覆盖预加载？

另一个.net新手问题

我创建了一个继承System.Web.UI.Page的类，目的是覆盖预加载和卸载功能。但 Visual Studios 抱怨我无法覆盖，因为“System.Web.UI.Page.PreLoad”不是一个函数。我的代码有什么问题吗？就是这样：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;

public partial class BTPage : System.Web.UI.Page
{
    protected SqlConnection cnx;

    public override void PreLoad(object sender, EventArgs e)
    {
        cnx = new SqlConnection(ConfigurationManager.AppSettings["btdatabase"]);
        cnx.Open();
    }

    protected void Unload(object sender, EventArgs e)
    {
        cnx.Close();
    }
}

如果我的代码还有其他令人担忧的地方，请告诉我。我是 .Net 的新手，我不确定我是否以“.NET 方式”做事。

我还想做的是让每个网页都继承自 BTPage，以便它们都在预加载时打开与数据库的连接。

Another .net newbie question

I created a class that inherits System.Web.UI.Page with the intention of overriding the preload and Unload functions. But Visual Studios complains I can't override because "System.Web.UI.Page.PreLoad" is not a function. What's wrong with my code? Here it is:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Configuration;

public partial class BTPage : System.Web.UI.Page
{
    protected SqlConnection cnx;

    public override void PreLoad(object sender, EventArgs e)
    {
        cnx = new SqlConnection(ConfigurationManager.AppSettings["btdatabase"]);
        cnx.Open();
    }

    protected void Unload(object sender, EventArgs e)
    {
        cnx.Close();
    }
}

If there's anything else alarming about my code, please tell me. I'm new to .Net and I'm not sure if I'm doing things in the ".NET way".

What I also want to do is have every web page inherit from BTPage so that they all open a connection to the database on preload.
