我正在尝试将 Visual Studio 中的登录控件与我的 Access 数据库一起使用。我不确定如何使用这两个。这是我到目前为止所拥有的：
登录.aspx：
<%@ Page Title="Login" Language="C#" MasterPageFile="~/EditSite.master" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Login ID="Login1" runat="server">
</asp:Login>
</asp:Content>
这是背后的代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Security;
using System.Data;
using System.Data.OleDb;
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
ViewState["LoginErrors"] = 0;
}
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
if (YourValidationFunction(Login1.UserName, Login1.Password))
{
e.Authenticated = true;
Login1.TitleText = "Successfully Logged In";
} else {
e.Authenticated = false;
}
}
protected void Login1_LoginError(object sender, EventArgs e)
{
if (ViewState["LoginErrors"] == null)
ViewState["LoginErrors"] = 0;
int ErrorCount = (int)ViewState["LoginErrors"] + 1;
ViewState["LoginErrors"] = ErrorCount;
if ((ErrorCount > 3) && (Login1.PasswordRecoveryUrl != string.Empty))
Response.Redirect(Login1.PasswordRecoveryUrl);
}
private bool YourValidationFunction(string UserName, string Password)
{
bool boolReturnValue = false;
string constr = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\TravelJoansDB.mdb;";
OleDbConnection con = new OleDbConnection(constr);
String SQLQuery = "SELECT UserName, Password FROM Login";
OleDbCommand com = new OleDbCommand(SQLQuery, con);
OleDbDataReader Dr;
con.Open();
Dr = com.ExecuteReader();
while (Dr.Read())
{
if ((UserName == Dr["UserName"].ToString()) & (Password == Dr["Password"].ToString()))
{
boolReturnValue = true;
}
Dr.Close();
return boolReturnValue;
}
return boolReturnValue;
}
}
这是网络配置：

If you are deploying to a cloud environment that has multiple web server instances,
you should change session state mode from "InProc" to "Custom". In addition,
change the connection string named "DefaultConnection" to connect to an instance
of SQL Server (including SQL Azure and SQL Compact) instead of to SQL Server Express.

任何帮助将不胜感激。当我单击登录按钮时，它给出了一个关于找不到网络相关实例的错误。我在文件夹上设置了安全设置，以便所有人都能完全控制。
