Compiler Warning (level 3) CS0169

The private field 'class member' is never used

A private variable was declared but never referenced. A common way to generate this warning is when you declare a private member of a class and do not use it.

The following sample generates CS0169:

// compile with: /W:3
using System;
public class ClassX
{
   int i;   // CS0169, i is not used anywhere

   public static void Main()
   {
   }
}
