assigning static to an object property

Question

Why is it when I do something as follows:

C#

public readonly string _objectString = ExtNameSpace.StaticClass.MyVar;

where MyVar is defined inside the static class StaticClass as

public static readonly string MyVar

I get the following error:

An object reference is required for the nonstatic field, method, or property

I was expecting this to happen the other way around, ie if I am assigning an object variable to a static member variable.

You just need to understand how instance (non-static) methods work; which is one of the starting point to get before to understand OOP.

Please see my past solution where I explain it in a pretty detailed manner: What makes static methods accessible?[^].

I'm unable to reproduce this behavior in .NET 4.0. Which version of .NET are you using ?

The only scenario I can think of that would produce the error message you report is if you tried to define MyVar the way it is now (non-static) inside another class which is static.

If that's the case then simply change 'MyVar's declaration to:

public static readonly string _objectString = ExtNameSpace.StaticClass.MyVar;

If that's not an answer, please show a selection of your code at the place where the variable _objectString is defined, and the declaration for the class it occurs in.
