QuestionHow to create a many-to-many relationship between users in a table? Pin

I'm working on an ASP.NET Core web API and SQLite database. I have created a table for users of my application. The rule is that each user can send a message to some other users (creating White-List). I use the following model for Users:

public class UserModel
{
    [Key]
    public int UserID { get; set; }
    [Required]
    public string Username { get; set; }
    [Required]
    public string Password { get; set; }
    [Required]
    public string FirstName { get; set; }
    [Required]
    public string LastName { get; set; }
    [Required]
    public string Role { get; set; }

    //Navigation property
    public Department Department { get; set; }
}


My desired table is:

C#
User-SubUser table
------------------------------------
UserID          ReceiverUserID
------          --------------
23                    11
42                    11
19                    -
34                    23


Note that the IDs mentioned above are the UserIDs from the User table. This table says that users 23 and 42 can send a message to user 11, user 34 can send a message to user 23, and user 19 cannot send message to anyone.

How can I make a model for creating such a table?
