How can I access a variable in one public class from another public class in C#?
I have:
public class Variables
{
static string name = "";
}
I need to call it from:
public class Main
{
}
I am working in a Console App.

That would just be:
Console.WriteLine(Variables.name);
and it needs to be public also:
public class Variables
{
public static string name = "";
}

are you sure you added the public modifier.

I get an object reference is required for non-static field.
I would suggest to use a variable instead of a public field:
public class Variables
{
private static string name = "";
public static string Name
{
get { return name; }
set { name = value; }
}
}
From another class, you call your variable like this:
public class Main
{
public void DoSomething()
{
string var = Variables.Name;
}
}

Actually, it would be better for him to not have variables within a static class.

why do you say that...why not?

It may just be me, but I think it is good practice to make static classes completely stateless.

@Chaos: Well, I could agree with you. But in this case, the variable name seems to be a constant and it seems to me more elegant to use a static variable.

why not use (public const String name = "MyName";) ?
You need to specify an access modifier for your variable. In this case you want it public.
public class Variables
{
public static string name = "";
}
After this you can use the variable like this.
Variables.name
