Answer 1

一楼的回答不对，严重错误！
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class LoginControl : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e);
}
中的
protected void Page_Load(object sender, EventArgs e);
}
改成
protected void Page_Load(object sender, EventArgs e)
{
}

Answer 2

第一处错误：
public partial class LoginControl:System.Web.UI.UserControl
{
public string BackColor
{
get
{
return MyTable.BgColor;
}
set
{
MyTable.BgColor=value;
}
}
public string UserName
{
get
{
return tbUserName.Text;
}
set
{
tbUserName.Text=value;
}
}
public string UserPwd
{
get
{
return tbUserPwd.Text;
}
set
{
tbUserPwd.Text=value;
}
}
这串代码的末尾少了一个花括号
第二处错误：
protected void Page_Load(object sender, EventArgs e);
}
这串代码的花括号写反了。

Answer 3

protected void Page_Load(object sender, EventArgs e);
