Parameters

item

The object to locate in the current instance.

Returns

true if item is contained in the current instance; otherwise, false.

Remarks

Note: This method is implemented to support the IList interface.

Operation

As described above.

This method determines equality by calling the object.Equals(object) implementation of the type of item.

Note: For the default implementation, this method is an O(n) operation where n is equal to the ArrayList.Count of the current instance. If the current instance is sorted, it is more efficient to call ArrayList.BinarySearch(int, int, object, IComparer) method.

Requirements

Namespace: System.Collections
Assembly: mscorlib (in mscorlib.dll)
Assembly Versions: 1.0.5000.0, 2.0.0.0
