我收到错误“类型与导入的类型冲突

Question

I have created a class file in C# called Users. I want to create an instance of a class from within the same class file. I thought had been able to do this in the past. When I try here. I get the message "The type Users in "" conflicts with the imported type "Users" in.

Is it possible to create an instance of a class within the class file itself. If so, can someone tell me what I am missing?

 public class Users
    {
   
public int ID { get; set; }
public int Cityid { get; set; }
public bool Active { get; set; }
     
        
public Users GetUserforedit(int id)

Answer 1

I see no reason why you couldn't have an instance method of a class that returned an instance of the class itself, although it's more common to make such a method a static method rather than an instance method.

(In fact, if you couldn't do that, you wouldn't be able to have methods like Clone() )

As for your error messages, two possibilities occur:

The most obvious cause would be that there's another class called Users in either the same namespace, or a namespace you're importing. Do you have a web page called Users ? Another, earlier version of your class file, perhaps?

The other possibility would be that your class not being within a namespace is somehow confusing the compiler. Try wrapping the class in a namespace, and see if you now get at least a more useful error message.

I created an example that is similar to your example and does what you want.

    public class User
    {
        public int Id { get; set; }
        public int Cityid { get; set; }
        public bool Active { get; set; }
       
        private User GetUserForEdit(int id)
        {
            return new User()
            {
                Id = id,
                Active = true,
                Cityid = 1
            };
        }
        public void TestUser()
        {
            User user = GetUserForEdit(1); //creating an instance of a class within the class file itself.
            Console.WriteLine(user.Id + " " + user.Active + " " + user.Cityid);
        }
    }
 

        static void Main(string[] args)
        {
            User user = new User();
            user.TestUser();

            Console.ReadLine();
        }
