Removes the first occurrence of a specific object from the Collection(T).
Assembly: mscorlib (in mscorlib.dll)
Return ValueType: System.Boolean
true if item is successfully removed; otherwise, false. This method also returns false if item was not found in the original Collection(T).
This method determines equality using the default equality comparer EqualityComparer(T).Default for T, the type of values in the list.Notes to Inheritors
Derived classes can override RemoveItem to change the behavior of this method.
The following code example demonstrates many of the properties and methods of Collection(T). The code example creates a collection of strings, uses the Add 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 method and by index using the RemoveAt method. Finally, the Clear method is used to clear all strings from the collection.
