在另一个类c#中调用var用户

Question

我有一个名为var users=JsonConvert.DeserializedObject<User[]>(jsonResponse)的变量，它位于Login.cs is public class login。

因此，我想要做的是调用Menu.cs中的Menu.cs，以便能够在var users中编辑相同的数据，但是我不能将var users声明为public var users，因为这是不允许的。所以我才想办法解决这个问题。

public class Login 
{
    public static string jsonResponse = File.ReadAllText("C:\\Users\\Admin\\C#_Activity 1\\Users.json");

    public static void LoginMenu()
    {
        var users = JsonConvert.DeserializeObject<User[]>(jsonResponse);
    }

}

public class Menu
{
     
    public static void BankMenu()
    {
        foreach (var user in users!)
        {
            Console.Writeline(user.FirstName); 
        }
    }
}

Users.json

[
  {
    "id": 1,
    "username": "sachin",
    "password": "sachin1",
    "firstName": "Sachin",
    "lastName": "Karnik",
    "birthdate": "2011-6-14",
    "balance": 20000,
    "cardNumber": 12345
  },
  {
    "id": 2,
    "username": "dina",
    "password": "dina1",
    "firstName": "Dina",
    "lastName": "Meyers",
    "birthdate": "2012-8-20",
    "balance": 20000,
    "cardNumber": 23456
  },
  {
    "id": 3,
    "username": "andy",
    "password": "andy1",
    "firstName": "Andy",
    "lastName": "Rose",
    "birthdate": "2010-2-11",
    "balance": 20000,
    "cardNumber": 34567
  }
]

Answer 1

使users成为公共静态成员，而不是jsonResponse。据我所知，没有理由让jsonReponse作为公共成员。就像这样：

public class Login 
{
    public static User[] Users { get; private set;}

    public static void LoginMenu()
    {
        var json = File.ReadAllText("C:\\Users\\Admin\\C#_Activity 1\\Users.json");
        Users = JsonConvert.DeserializeObject<User[]>(json);
    }
}
