Compiler Error CS0175

Use of keyword 'base' is not valid in this context

The base (C# Reference) keyword must be used to specify a particular member of the base class. For more information, see Constructors (C# Programming Guide).

The following sample generates CS0175:

// CS0175.cs
using System;
class BaseClass
    public int TestInt = 0;

class MyClass : BaseClass
    public static void Main()
        MyClass aClass = new MyClass();

    public void BaseTest()
        Console.WriteLine(base); // CS0175
        // Try the following line instead:
        // Console.WriteLine(base.TestInt);
        base = 9;   // CS0175

        // Try the following line instead:
        // base.TestInt = 9;
