Compiler Warning (level 1) CS0184

The given expression is never of the provided ('type') type

The expression can never be true because the variable you are testing is neither declared as type nor derived from type.

The following sample generates CS0184:

// CS0184.cs
// compile with: /W:1
class MyClass
   public static void Main()
      int i = 0;
      if (i is string)   // CS0184
