To access the target value indirectly pointed to by a pointer to a pointer, you must apply 

the asterisk operator twice, as in this example:

using System;

class MultipleIndirect {

  unsafe static void Main() {

    int x;   // holds an int value

    int* p;  // holds an int pointer

    int** q; // holds a pointer to an int pointer

    x = 10;

    p = &x; // put address of x into p

    q = &p; // put address of p into q

    Console.WriteLine(**q); // display the value of x

  }

}

The output is the value of
