How can I display a pointer address in C#?

I've not done any pointers since I've been programming in C# - and my C++ days were long ago. I thought I should refresh my knowledge and was just playing around with them because of another question on here. I understand them all okay, but I can't figure out how to write the pointer's address to the console...

char c = 'c';
char d = 'd';
char e = 'e';

unsafe
{
    char* cp = &d;
    //How do I write the pointer address to the console?
    *cp = 'f';
    cp = &e;
    //How do I write the pointer address to the console?
    *cp = 'g';
    cp = &c;
    //How do I write the pointer address to the console?
    *cp = 'h';        
}
Console.WriteLine("c:{0}", c); //should display "c:h";
Console.WriteLine("d:{0}", d); //should display "d:f";
Console.WriteLine("e:{0}", e); //should display "e:g";

Using Console.WriteLine(*cp); gives me the current value at the pointer address... what if I want to display the actual address?

Console.WriteLine(new IntPtr(cp));
