member names cannot be the same as their enclosing type C#

The code below is in C# and I'm using Visual Studio 2010.

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

namespace FrontEnd
{
    class Flow
    {
        long i;
        private int x,y;
        public int X
        {
            get;set;
        }
        public int Y
        {
            get;set;
        }

        private void Flow()
        {
            X = x;
            Y = y;
        }

        public void NaturalNumbers(int x, int y)
        {
            for (i = 0; i < 9999; i++)
            {
                Console.WriteLine(i);
            }
            MessageBox.Show("done");
        }
    }
}

When I compile the above code I get this error:

Error: 'Flow': member names cannot be the same as their enclosing type

Why? How can I resolve this?

Solution 1:

Method names which are same as the class name are called constructors. Constructors do not have a return type. So correct as:

private Flow()
{
   X = x;
   Y = y;
}

Or rename the function as:

private void DoFlow()
{
   X = x;
   Y = y;
}

Though the whole code does not make any sense to me.

Solution 2:

The problem is with the method:

private void Flow()
{
    X = x;
    Y = y;
}

Your class is named Flow so this method can't also be named Flow. You will have to change the name of the Flow method to something else to make this code compile.

Or did you mean to create a private constructor to initialize your class? If that's the case, you will have to remove the void keyword to let the compiler know that your declaring a constructor.

Solution 3:

Constructors don't return a type , just remove the return type which is void in your case. It would run fine then.

Solution 4:

As Constructor should be at the starting of the Class , you are facing the above issue . So, you can either change the name or if you want to use it as a constructor just copy the method at the beginning of the class.
