我正在我的MVC项目的登录页面上工作。MVC登录功能
我想用一个已经存在的名为DEVE03的数据库来构建它。在DEVE03数据库中，我有一个名为User的表。我在这里跟着一个教程：http://www.c-sharpcorner.com/article/Asp-Net-mvc-5-integrating-existing-database-with-login-usin/它工作正常。但在教程中，他使用存储过程，并使用表格。
除了一件以外，每一样东西都可以使用。代码的这一部分是什么var loginInfo = this.databaseManager.User(model.LogonName, model.LogonPassword).ToList();用户给我一个错误，说明非invocable成员Entities.User不能像方法一样使用。
我已经看到相当多的人有同样的问题，人们建议他们应该删除大多数人解决问题的括号。但是，当我删除它的作品，我可以登录。但我可以登录每个可能的登录名和登录密码。当我登录时，登录帐户是我的表中的第一个帐户。
我已经连接到我的数据库visual studio，并且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

LoginViewModel：
public class LoginViewModel

[Required]
[Display(Name = "Email")]
[EmailAddress]
public string LogonName { get; set; }
[Required]
[DataType(DataType.Password)]
public string LogonPassword { get; set; }
public bool RememberMe { get; set; }
}
和用户表看起来这样的：我用它来登录例如
UserID LogonName LogonPassword
1 [email protected] Welcome123
2 [email protected] Welcome1234
3 [email protected] Welcome12345
所以，无论电子邮件住址：[email protected]他会登录到[email protected]。
我希望你们能帮我解决我的问题。
让我知道如果我错过了你可能需要解决的任何代码。
是的我有，但是当我删除括号并且用[email protected]登录时，它使用帐户[email protected]登录我。所以没有进行验证。 – HJarry
请分享databaseManager.MDFUser（）方法代码。 – Conqueror
它在我上面显示的accountcontroller我认为 – HJarry
