ContainsValue Method

SortedList<TKey, TValue>.ContainsValue Method

Determines whether the SortedList<TKey, TValue> contains a specific value.

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

public bool ContainsValue(
	TValue value


Type: TValue
The value to locate in the SortedList<TKey, TValue>. The value can be null for reference types.

Return Value

Type: System.Boolean
true if the SortedList<TKey, TValue> contains an element with the specified value; otherwise, false.

This method determines equality using the default comparer Comparer<T>.Default for the value type TValue. Comparer<T>.Default checks whether the value type TValue implements System.IComparable<T> and uses that implementation, if available. If not, Comparer<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.
