Creating a Chatroom project in C# — But what's wrong in my code?

Hi guys, I just finished the C# Objects course, and I wanted to make a Chatroom application. (Yes, it is text-based and not over the Internet.)

I've already made a pretty decent one with Python. I wanted to try to do it as well with C#, because I felt that I learned enough from the course to be able to.

By the way, I'm fairly new to C#, so sorry if the error is obvious :smirk:

Here's my User class:

using System;

namespace Chatroom
{
    class User
    {

        public string Username { get; }
        public string FullName { get; set; }
        public string Email { get; set; }
        public string Bio { get; set; }

        private readonly string _password;
        private const string line = "-" * 30;

        public static void User(string username, string fullName,
                                string email, string password)
        {
            Username = username;
            FullName = fullName;
            Email = email;
            _password = password;
        }

        public void DisplayUser()
        {
            Console.WriteLine(line);
            Console.WriteLine(Username);
            Console.WriteLine(line);

            Console.WriteLine("Full name: " + FullName);
            Console.WriteLine("Email: <" + Email + ">");
            Console.WriteLine(line);

            Console.WriteLine(Bio);
            Console.WriteLine(line);
        }

    }
}

My console output:

treehouse:~/workspace$ mcs -out:Chatroom.exe *.cs && mono Chatroom.exe

I can't seem to see any kind of error here. Can somebody give me a hand? Thank you :smile:

:mailbox_with_mail: I got your message.

But it looks like Mikis already has you covered. I would just add that the reason you can't use the class name as a method name is because it would appear to be a constructor.

But one error message you got is most curious: "Chatroom.cs(10,63): error CS1525: Unexpected symbol 'GPIOpython_'" — Where the heck does that come from?

I posted the Chatroom.cs file's code below, just FYI.

Hi Alexander,

I'm not too familiar with C# but — from the error message — it seems like you can't have static methods that have the same name as their class; that is, User.User is illegal.

Thank you! it fixed one of the errors.

However, after fixing that, I still get this error:

treehouse:~/workspace$ mcs -out:Chatroom.exe *.cs && mono Chatroom.exe                                                                                                 
Chatroom.cs(10,34): error CS1525: Unexpected symbol `alexdavison888@gmail.com'                                                                                         
Chatroom.cs(10,63): error CS1525: Unexpected symbol `GPIOpython__'                                                                                                     
Compilation failed: 2 error(s), 0 warnings

Also, just in case you want to see, this is my Chatroom class:

namespace Chatroom
{
    class Chatroom
    {

        static void Main()
        {

            User user = new User("xela888", "Alexander Davison"
                                 "alex@gmail.com", "password");

        }

    }
}

You're missing a comma after "Alexander Davison" when you initialize User in Main().
