How can I assign this list of strings to an integer array?

I have a list of numbers that is of a string type.  I want to stuff those into an integer array.
At the end of the process I want to have an int array that is dynamic in size.

tagIDList = "1230,12312,12312";
int[] foodWeightLossSystemTags = tagIDList.Split(new char[] {','});

string[] dummy = tagIDList.Split(new char[] {','});
int[] foodWeightLossSystemTags = new int[dummy.Length];
for(i=0;i<dummy.Length;i++) {
  foodWeightLossSystemTags[i] = Int32.Parse(dummy[i]);
}

So I knew that when I do a loop I will be able to parse it out, but I though there is a trick without a loop.  Sorry I should have put that in my question.

I'm going to assume there is no trick and I will loop through.

Thanks.

nah.. there is no trick.  You have to "brute force" it.

If you wanted to add all of those elements to an array list, there is a trick for that....  Since all arrays inherit from ICollectionBase you can simply instantiate your arraylist with an array as a prameter


string[] myStrs = {"1","2","3","4"};
ArrayList al = new ArrayList(myStrs);

but then if you want the integer value you'll still need to parse the object

int i = int.Parse(al[2]);

No 'tricks' on C# 1.1 but in C# 2.0 you get generics whic will allow you do this this somewhat more elegantly than ye olde for loop.

you can simplify this line from:
string[] dummy = tagIDList.Split(new char[] {','});

to:

string[] dummy = tagIDList.Split(',');

you don't need to create an array
