Important

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