ArrayList.FixedSize Method (IList)
Returns an IList wrapper with a fixed size.
Assembly: mscorlib (in mscorlib.dll)
This wrapper can be used to prevent additions to and deletions from the original IList. The elements can still be modified or replaced.
A collection with a fixed size is simply a collection with a wrapper that prevents adding and removing elements; therefore, if changes are made to the underlying collection, including the addition or removal of elements, the fixed-size collection reflects those changes.
This method is an O(1) operation.
