Adds an object to the end of the Collection(T).
Assembly: mscorlib (in mscorlib.dll)
Collection(T) accepts a null reference (Nothing in Visual Basic) as a valid value for reference types and allows duplicate elements.
This method is an O(1) operation.
The following code example demonstrates many of the properties and methods of Collection(T). The code example creates a collection of strings, uses the method to add several strings, displays the Count, and lists the strings. The example uses the IndexOf method to find the index of a string and the Contains method to determine whether a string is in the collection. The example inserts a string using the Insert method and retrieves and sets strings using the default Item property (the indexer in C#). The example removes strings by string identity using the Remove method and by index using the RemoveAt method. Finally, the Clear method is used to clear all strings from the collection.
