SynchronizedKeyedCollection<K, T> Constructor (Object, IEqualityComparer<K>)

 

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.

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

protected SynchronizedKeyedCollection(
	object syncRoot,
	IEqualityComparer<K> comparer
)

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.
