C# Function question

[Scott Schaffer]

Hello,
This should be a simple problem to solve, but I'm fairly new to C# and
have been wracking my brains to no avail. I created a new Console
Application in C# beta 2, and entered the following:

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

namespace Test2
{
class Program
{
static void main (string[] args)
{
string a = "qwert";
string b = GetStuff( );
string c = a + b;
Console.WriteLine(c);
}

public string GetStuff( )
{
string c = "poiuy";
return c;
}
}
}

When I compile this, I get the error: "An object reference is required
for the nonstatic field, method, or property 'Test2.Program.GetStuff( )' for
the line: string b = GetStuff( );

I'm not entirely sure what the problem could be, and would appreciate it
if someone help. Thanks.

you require the following:

class Program
{
static void main (string[] args)
{
Program p = new Program();
string a = "qwert";
string b = p.GetStuff( );
string c = a + b;
Console.WriteLine(c);
}

If you change GetStuff to be a "static" method, like Main, it will
compile.

Alternatively, you can put your code in one or more separate classes
(a better idea for large projects) and then Main could create an
instance (Thing t = new Thing();) and call non-static methods on the
instance of the class. Look up "static" in the help to learn more
about static vs. class methods.

To call non-static methods you need an object instance.

This means that since main is a static method, it cannot call other
non-static methods of the same class, unless you first construct an
object (Program object) and call the method through that.

The solution is either:

1. Construct an instance of Program and call GetStuff through that:

Program p = new Program();
string b = p.GetStuff();

or:
2. Make GetStuff a static method as well
