I'm new to C# and need some help with a small program I'm trying to code. I use Microsoft Visual C# Express 2008 for my coding as I am currently a student. Here is the code that I am having trouble with:

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Vehicle
{
    class Vehicle
    {
        //Variable declaration
        public string Make = "";
        public string Model = "";
        public int Condition = 0;
        public double Price = 0;
        
        //Empty constructor
        public Vehicle()
        {
        }

        //Constructor
        public Vehicle(string newMake, string newModel, int newCondition, double newPrice)
        {
            Make = newMake;
            Model = newModel;
            Condition = newCondition;
            Price = newPrice;
        }
    }
}

The following error messages are what I am receiving:

C#

1 Ambiguity between 'Vehicle.Vehicle.Make' and 'Vehicle.Vehicle.Make'
2 Ambiguity between 'Vehicle.Vehicle.Model' and 'Vehicle.Vehicle.Model'
3 Ambiguity between 'Vehicle.Vehicle.Condition' and 'Vehicle.Vehicle.Condition'
4 Ambiguity between 'Vehicle.Vehicle.Price' and 'Vehicle.Vehicle.Price'

Any help as to how to resolve this will be much appreciated :)

Of course there is nothing wrong about this code; it compiles perfectly. Most likely, you used the same name in some other file, that's it.

Having the namespace same as some class is a bad naming style and does not make much sense, but not really a mistake. I did not mention the quality of this code, but at least never use "", use string.Empty instead.

It's funny that two people gave wrong answers not trying to compile this code. It compiles, don't worry.

Odd, you should be getting an error saying that the class cannot have the same name as its enclosing namespace... try renaming the namespace (to something like VehicleExercise, say) and see if the errors go away.

AFAIK a class can have the same name as the enclosing namespace, don't know of anything that prevents.

Oh, maybe it was that a property cannot have the same name as its enclosing class - sorry!

Your class must be Public

C#

public class Vehicle
    {
        //Variable declaration
        public string Make{get; set;}        
        public string Model{get; set;}
        public int Condition{get; set;}
        public double Price{get; set;}

        //Empty constructor
        public Vehicle():this(string.Empty, string.Empty, 0, 0)
        {
        }

        //Constructor
        public Vehicle(string newMake, string newModel, int newCondition, double newPrice)
        {
            Make = newMake;
            Model = newModel;
            Condition = newCondition;
            Price = newPrice;
        }
    }
