我正在我的MVC項目的登錄頁面上工作。MVC登錄功能
我想用一個已經存在的名爲DEVE03的數據庫來構建它。在DEVE03數據庫中，我有一個名爲User的表。我在這裏跟着一個教程：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，他使用存儲過程，並使用表格。
除了一件以外，每一樣東西都可以使用。代碼的這一部分是什麼var loginInfo = this.databaseManager.User(model.LogonName, model.LogonPassword).ToList();用戶給我一個錯誤，說明非invocable成員Entities.User不能像方法一樣使用。
我已經看到相當多的人有同樣的問題，人們建議他們應該刪除大多數人解決問題的括號。但是，當我刪除它的作品，我可以登錄。但我可以登錄每個可能的登錄名和登錄密碼。當我登錄時，登錄帳戶是我的表中的第一個帳戶。
我已經連接到我的數據庫visual studio，並且我已經創建了一個名爲CMS的實體數據模型。
我希望你們能幫助我

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; }
}
和用戶表看起來這樣的：我用它來登錄例如
UserID LogonName LogonPassword
1 [email protected] Welcome123
2 [email protected] Welcome1234
3 [email protected] Welcome12345
所以，無論電子郵件住址：[email protected]他會登錄到[email protected]。
我希望你們能幫我解決我的問題。
讓我知道如果我錯過了你可能需要解決的任何代碼。
是的我有，但是當我刪除括號並且用[email protected]登錄時，它使用帳戶[email protected]登錄我。所以沒有進行驗證。 – HJarry
請分享databaseManager.MDFUser（）方法代碼。 – Conqueror
它在我上面顯示的accountcontroller我認爲 – HJarry
