What is a field in C# and why would I use it?
<p>I am learning C# and I would like to know what is the use of a field in a C# class?</p>

<p>example </p>

<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Class_Constructor_II
{
class Fields
{
    const double RandsInADollar = 7.8;
    const double RandsInAEuro = 10.83

    public double RandDollarConversion
    {
        get
        {
            return RandsInADollar / DollarRands; 
        }
        set
        {
            DollarRands = value / RandsInADollar;
        }

    }
    public double DollarRands
    {
        get;
        set;
    }

}
class Program
{
    static void Main(string[] args)
    {
        Fields f = new Fields();
         f.DollarRands = 14500000;
        Console.WriteLine(f.DollarRands);

    }
}
}
</code></pre>
