Compiler Error CS0242

The operation in question is undefined on void pointers

Incrementing a void pointer is not allowed. For more information, see Unsafe Code and Pointers.

The following sample generates CS0242:

// CS0242.cs  
// compile with: /unsafe  
class TestClass  
{  
   public unsafe void Test()  
   {  
      void * p = null;  
      p++;   // CS0242, incrementing a void pointer not allowed  
   }  
  
   public static void Main()  
   {  
   }  
}
