Compiler Error CS0175

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

The base keyword must be used to specify a particular member of the base class. For more information, see Constructors.

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();  
        aClass.BaseTest();  
    }  
  
    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;  
    }  
}
