Definition

public:
 virtual bool Contains(System::Object ^ value);
public virtual bool Contains (object value);
abstract member Contains : obj -> bool
override this.Contains : obj -> bool
Public Overridable Function Contains (value As Object) As Boolean

Parameters

value
Object

The Object to locate in the underlying list represented by the List property. The value can be null.

Returns

true if the value parameter is found in the List; otherwise, false.

Implements

Remarks

Although the implementation is dependent on the underlying list's Contains method, typically the following characteristics apply:

  • List is searched starting at the first element and ending at the last element.

  • The underlying method performs a linear search; therefore, the average execution time is proportional to the value of the Count property.

  • The underlying method determines equality by calling the Equals method.
