SynchronizedKeyedCollection<K, T> Constructor (Object, IEqualityComparer<K>)
.NET Framework (current version)
Initializes a new instance of the SynchronizedKeyedCollection<K, T> class with access synchronized by an explicitly specified object and with keys compared in a specified way.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Parameters
- syncRoot
-
Type:
System.Object
The object used to synchronize access to the thread-safe collection.
- comparer
-
Type:
System.Collections.Generic.IEqualityComparer<K>
The IEqualityComparer<T> of type K used to compare key objects of type K for equality.
| Exception | Condition |
|---|---|
| ArgumentNullException | syncRoot is null or comparer is null. |
The generic parameter K used by the IEqualityComparer<T> input parameter is the first generic parameter for this class. This allows us to compare keys for equality in a customized way that can be used, for example, to optimize on the most critical aspects of the comparison.
