Initializes a new instance of the SynchronizedKeyedCollection<K,T> class.
Overloads
| SynchronizedKeyedCollection<K,T>() |
Initializes a new instance of the SynchronizedKeyedCollection<K,T> class. |
| SynchronizedKeyedCollection<K,T>(Object) |
Initializes a new instance of the SynchronizedKeyedCollection<K,T> class with access synchronized by an explicitly specified object. |
| SynchronizedKeyedCollection<K,T>(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. |
| SynchronizedKeyedCollection<K,T>(Object, IEqualityComparer<K>, Int32) |
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. |
SynchronizedKeyedCollection<K,T>()
Initializes a new instance of the SynchronizedKeyedCollection<K,T> class.
protected:
SynchronizedKeyedCollection();protected SynchronizedKeyedCollection ();Protected Sub New ()Applies to
SynchronizedKeyedCollection<K,T>(Object)
Initializes a new instance of the SynchronizedKeyedCollection<K,T> class with access synchronized by an explicitly specified object.
protected:
SynchronizedKeyedCollection(System::Object ^ syncRoot);protected SynchronizedKeyedCollection (object syncRoot);new System.Collections.Generic.SynchronizedKeyedCollection<'K, 'T> : obj -> System.Collections.Generic.SynchronizedKeyedCollection<'K, 'T>Protected Sub New (syncRoot As Object)Parameters
- syncRoot
- Object
The object used to synchronize access to the thread-safe collection.
Exceptions
syncRoot is null.
Remarks
If multiple instances of the SynchronizedKeyedCollection<K,T> are created using the same syncRoot, then access is protected across all instances.
Applies to
SynchronizedKeyedCollection<K,T>(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.
protected:
SynchronizedKeyedCollection(System::Object ^ syncRoot, System::Collections::Generic::IEqualityComparer<K> ^ comparer);protected SynchronizedKeyedCollection (object syncRoot, System.Collections.Generic.IEqualityComparer<K> comparer);new System.Collections.Generic.SynchronizedKeyedCollection<'K, 'T> : obj * System.Collections.Generic.IEqualityComparer<'K> -> System.Collections.Generic.SynchronizedKeyedCollection<'K, 'T>Protected Sub New (syncRoot As Object, comparer As IEqualityComparer(Of K))Parameters
- syncRoot
- Object
The object used to synchronize access to the thread-safe collection.
- comparer
- IEqualityComparer<K>
The IEqualityComparer<T> of type K used to compare key objects of type K for equality.
Exceptions
syncRoot is null or comparer is null.
Remarks
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.
Applies to
SynchronizedKeyedCollection<K,T>(Object, IEqualityComparer<K>, Int32)
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.
protected:
SynchronizedKeyedCollection(System::Object ^ syncRoot, System::Collections::Generic::IEqualityComparer<K> ^ comparer, int dictionaryCreationThreshold);protected SynchronizedKeyedCollection (object syncRoot, System.Collections.Generic.IEqualityComparer<K> comparer, int dictionaryCreationThreshold);new System.Collections.Generic.SynchronizedKeyedCollection<'K, 'T> : obj * System.Collections.Generic.IEqualityComparer<'K> * int -> System.Collections.Generic.SynchronizedKeyedCollection<'K, 'T>Protected Sub New (syncRoot As Object, comparer As IEqualityComparer(Of K), dictionaryCreationThreshold As Integer)Parameters
- syncRoot
- Object
The object used to synchronize access to the thread-safe collection.
- comparer
- IEqualityComparer<K>
The IEqualityComparer<T> of type K used to compare key objects of type K for equality.
- dictionaryCreationThreshold
- Int32
The number of items required to create a dictionary for the collection.
Exceptions
syncRoot is null or comparer is null.
dictionaryCreationThreshold is less than -1.
Remarks
Setting dictionaryCreationThreshold to -1 assigns the MaxValue (2,147,483,647; hexadecimal 0x7FFFFFFF) to it.
