pointer

Question

I am new in C#ing and I wanna know if someone can tell me how to use pointers in the way I could use theme in Pascal or Delphi. I learned to use array in C# and I think that it is just a simulation of classic oldstyle stack array. Now it is written in Heap and if someone could explain me (with example) how can I do next thing for example: I defined an array of 100 elements and i want to add 101 element how to make it happend (since it is heap mem) or how lo lower it to 99. or to erase 63-ird element and override 62 to 64th but all this WITHOUT DELITING OTHER ELEMENTS IN ARRAY.... I mean all those things I could do with pointers in pascal.... Thank you! Nenad

Well C# doesn't use pointers like C++. Im not too familiar with delphi and pascal so i wouldn't know about them. You are able to pass by reference and as an out param in C# though. Yes when you create a new array in C# it is put on the heap. A good place to start with eliminating array elements shrinking or expanding them is to look at the ArrayList class in the System.Collections namespace. It is specifically designed for that use. Other then that i would just assign the specific element im interested in to null and then create a new object in that slot for future use. Let me know if this helps.
