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

public:
 bool ContainsValue(TValue value);
public bool ContainsValue (TValue value);
member this.ContainsValue : 'Value -> bool
Public Function ContainsValue (value As TValue) As Boolean

Parameters

value
TValue

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

Returns

Boolean

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

Remarks

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.
