C#: An object reference is required for the non-static field, method, or Property
- by Omin
I feel bad for asking this when there are so many questions that are related but I was not able to find/understand the answer I am looking for.
// 2. Develop a program to convert currency X to currency Y and visa versa.
using System;
class Problem2
{
static void Main (string[] args)
{
while (true) {
Console.WriteLine ("1. Currency Conversion from CAD to Won");
Console.WriteLine ("2. Currency Conversion from Won to Cad");
Console.Write ("Choose from the Following: (1 or 2)? ");
int option = int.Parse( Console.ReadLine() );
//double x;
if (option == 1) {
Console.WriteLine ("Type in the amount you would like to Convert CAD to Won: ");
//double y =double.Parse( Console.ReadLine());
//Console.WriteLine( cadToWon( y ) );
Console.WriteLine( cadToWon( double.Parse( Console.ReadLine() ) ));
}
if (option == 2) {
Console.WriteLine ("Type in the amount you would like to Convert Won to CAD: ");
Console.WriteLine( wonToCad (double.Parse( Console.ReadLine())));
}
}
}
double cadToWon( double x )
{
return x * 1113.26;
}
double wonToCad( double x)
{
return x / 1113.26;
}
}
This give me the Error messgae "An object reference is required for the non-static field, method, or property 'Problem2..." I know that I'll be able to run the program if I add static infront of the methods but I'm wondering why I need it (I think it's because Main is static?) and what do I need to change in order to use these methods without adding static to them?
Thank you
