我正在MVC项目的登录页面上工作。
我想用一个名为DEVE03的现有数据库构建它。在DEVE03数据库中，我有一个名为User的表。我按照这里的教程：http://www.c-sharpcorner.com/article/Asp-Net-mvc-5-integrating-existing-database-with-login-usin/工作正常。但是在教程中他使用了存储过程，而我正在使用表。
除了一个以外，每件事都有效。代码的这一部分是哪个var loginInfo = this.databaseManager.User(model.LogonName, model.LogonPassword).ToList();用户给出了一个错误，指出不可调用的成员Entities.User不能像方法一样使用。
我见过很多人有同样的问题，人们建议他们应该删除解决大多数人问题的括号。但是，当我删除括号时，我可以登录。但我可以使用每个可能的登录名和logonpassword登录。当我登录时，登录帐户是我表格中的第一个帐户。
我已经连接了我的数据库visual studio，我已经创建了一个名为CMS的实体数据模型。
我希望你们能帮助我

我希望你们能解决我的问题。
如果我错过了您可能需要解决的任何代码，请告诉我。
答案 0 :(得分：1)
因为他正在使用S.Proc LoginByUsernamePassword，所以它接受username和password作为参数（就像C＃中的方法一样）。
在您的情况下，MDFUser是数据库中的一个表，因此您无法做到这一点。
当你删除括号时，你有效地说：
var loginInfo = this.databaseManager.MDFUser.ToList();
为我提供MDFUser表
你需要查询这样的表格（如果语法不是100％现货，请原谅我。）
var loginInfo = this.databaseManager.MDFUser.Where(n=>n.username ==
model.username && n.password == model.password).ToList();
