IList Remove

Question

I have an IList and a ListBox.
I compare the items in IList and ListBox by a for loop.
if(they are equal)
remove from the IList.

I used Ilistobj.removeAt(loopNumber). // it throws error Collection was of a fixed size.

How to remove from that object.
I need that obj for someother purpose.

Why don't you adding the common items to a new list rather that removing it from existing one..... AAA BBB CCC EEE GGG IList _list1 = new List (); IList _list2 = new List (); _list1.Add(AAA); _list1.Add(BBB); _list1.Add(CCC); _list1.Add(DDD); _list1.Add(EEE); for (int i = 0; i { if (ListBox1.Items[i].Value.Equals(_list1[i])) { _list2.Add(_list1[i]); } } for (int i = 0; i { Response.Write(_list2[i]); }
