I'm learning how to program with C# WPF. I've created a class that derives from a base class. But there is only problem, it doesn't let me access variables from the base class even when my base class variables are public.

These are 2 seperate class files.

How do I use variables created from my base class, in my derived class?

Post your code as there is no way for us to determine what you might be doing without it.

file1: baseclass.cs

class baseclass

{

public int A = 10;

}

file2: derivedclass.cs

class derivedclass : baseclass

{

A = 20; //Compiler error here

}

Of course there is an error, you can't put executable code in a class without a method. Has nothing to do with the base class.

@Mien Tommy

try with this

...

class derivedclass: baseclass

{

  int b;

  b = a;

  //if you are using console application then write Console.Write(b); and if you are using winforms then write MessageBox.Show("{0}",b);

}

this is the simple example

You do realize that your code won't work either, as it's not in a method.
