SortedList(Of TKey, TValue).ContainsValue Method (TValue)

 

Determines whether the SortedList(Of TKey, TValue) contains a specific value.

Namespace:   System.Collections.Generic
Assembly:  System (in System.dll)

Public Function ContainsValue (
	value As TValue
) As Boolean

Parameters

value
Type: TValue

The value to locate in the SortedList(Of TKey, TValue). The value can be null for reference types.

Return Value

Type: System.Boolean

true if the SortedList(Of TKey, TValue) contains an element with the specified value; otherwise, false.

This method determines equality using the default comparer Comparer(Of T).Default for the value type TValue. Comparer(Of T).Default checks whether the value type TValue implements System.IComparable(Of T) and uses that implementation, if available. If not, Comparer(Of T).Default checks whether the value type TValue implements System.IComparable. If the value type TValue does not implement either interface, this method uses Object.Equals.

This method performs a linear search; therefore, the average execution time is proportional to Count. That is, this method is an O(n) operation, where n is Count.
