推荐答案

表示层-获取凭据并将其传递给业务逻辑层
业务逻辑层-验证凭据(使用来自数据库的LDAP/自定义身份验证).验证之后，您可以决定将输出存储到会话中，该会话将在所有页面之间共享.
数据访问层-使用它从数据库中提取相应的凭据(如果使用自定义身份验证)


一个简单的解决方案.

网站项目
1. Login.aspx.cs

Presentation Layer - get and pass the credentials to the Business Logic Layer
Business Logic Layer - validate the credentials (using either LDAP/ custom authentications from DB). After validation, you may decide to store the output to a session, which will be shared among all the pages.
Data Access Layer - use it to pull the respective credentials from DB (if you use your custom authentication)


A simple solution.

Website Project
1. Login.aspx.cs

public void btnLogin_click()
{
    //get both username & password and store it in string variables

    LoginControlClass logClass = new LoginControlClass();
logClass.IsAuthenticatedUser(userName, password);
}

BLL(类库)

BLL (Class Library)

public class LoginControlClass
{

   public bool IsAuthenticatedUser(string userName, string password)
   {
     //put in your logic to authenticate.
//If LDAP, get details from LDAP to validate uname/password
//If custom, then invoke data from DAL to validate username/ password.
LoginDal loginDal = new LoginDal();
User user = loginDal.RetrieveUserCredentials(userName, password);
//Check the variable inside user object to determine the authentication status.

 }


}

DAL(类库)

DAL (Class Library)

public class LoginDal
{
  public User RetrieveUserCredentials()
  {
//Query from DB to prepare User object. This can be a DTO. Remember not to save the password in User object, instead you may think of set the validated authentication result in a variable.
}

}
