Gets or sets the element at the specified index.
Assembly: mscorlib (in mscorlib.dll)
ArrayList accepts nullNothingnullptrunita null reference (Nothing in Visual Basic) as a valid value and allows duplicate elements.
This property provides the ability to access a specific element in the collection by using the following syntax: myCollection[index].
The C# language uses the this keyword to define the indexers instead of implementing the property. Visual Basic implements as a default property, which provides the same indexing functionality.
Retrieving the value of this property is an O(1) operation; setting the property is also an O(1) operation.
