copied!<p>You're using pointers and the 'address of operator' these are features commonly associated with C/C++ but are available in C# code within <code>unsafe</code> code blocks. I would recommend doing some general research on the concept because understanding the syntax alone will not be enough to effectively use them. I'll explain a few lines;</p> <pre><code> int * p; //a pointer (the address of) 4 bytes of memory for an int int a = 5; // normal allocation/initialization of int p = &a; //sets p to the address of a. Since p is a pointer, it holds an address // ampersand is the 'address of operator', it returns and address. so this assignment works p = a // will not compile. int* != int p == 5 // will not compile, int* != int *p == 5 // true. *pointer dereferences the pointer returning the value // found at the address p points to which is 5 so this is true. int * q = &a; // another pointer to the memory containing a p == q // true, both pointers contain the same value, some address which is usually displayed in hex like 0xFF110AB2 </code></pre> <p>A more common use of pointers would be something like;</p> <pre><code>int *p; // do something to get a length for an integer array at runtime p = new int[size]; // now I've allocated an array based on information found at run time! </code></pre> <p>The above operations are very common in C/C++ and completely necessary. In C# there's no point in doing this. It's being done for you under the covers already, and it will never make mistakes (like failing to free that memory I just allocated).</p>
