Easy array question

[wossname]

Can someone show me how to declare, initialise and fill an array of class objects when I don't know how many objects I need at the time. Could be 10, could be 1000, there is no way of checking beforehand.

This would be blissfully simple in VB because of Redim, but C# has to be a pain in the arse doesn't it

Help!

[1 is a prime!]

In C#, you can't declare an array, size it, add elements to it, and then resize it while keeping the original elements, as you could using Redim Preserve in VB.

There are two options - if you know how many items you are going to need in total before you start adding items, then do this:

string[] mValues;

int i = 10; //Get the number of values here.

mValues = new string[i];

mValues[0] = 123;
//etc...

If you don't know how many items you will need in total until after you've started adding elements, then don't use an array. You need to use the C# equivalent of a collection. The best one to use would probably be an ArrayList.

ArrayList mValues = new ArrayList();

mValues.Add("321321");
//etc...

//To get the values back, cast them:
MessageBox.Show((string)mValues[0]);

Hope this helps!
