Constructor & Destructor Documentation

◆ ThreadLocal() [1/4]

System.Threading.ThreadLocal< T >.ThreadLocal ( )

Initializes the T:System.Threading.ThreadLocal`1 instance.

Definition at line 251 of file ThreadLocal.cs.

◆ ThreadLocal() [2/4]

System.Threading.ThreadLocal< T >.ThreadLocal ( bool trackAllValues )

Initializes the T:System.Threading.ThreadLocal`1 instance and specifies whether all values are accessible from any thread.

Parameters

trackAllValues true to track all values set on the instance and expose them through the P:System.Threading.ThreadLocal`1.Values property; false otherwise.

Definition at line 260 of file ThreadLocal.cs.

◆ ThreadLocal() [3/4]

System.Threading.ThreadLocal< T >.ThreadLocal ( Func< T > valueFactory )

Initializes the T:System.Threading.ThreadLocal`1 instance with the specified valueFactory function.

Parameters

valueFactory The T:System.Func`1 invoked to produce a lazily-initialized value when an attempt is made to retrieve P:System.Threading.ThreadLocal`1.Value without it having been previously initialized.

Exceptions

T:System.ArgumentNullException valueFactory is a null reference (Nothing in Visual Basic).

Definition at line 270 of file ThreadLocal.cs.

◆ ThreadLocal() [4/4]

System.Threading.ThreadLocal< T >.ThreadLocal	(	Func< T >	valueFactory,
		bool	trackAllValues
	)

Initializes the T:System.Threading.ThreadLocal`1 instance with the specified valueFactory function and a flag that indicates whether all values are accessible from any thread.

Parameters

valueFactory	The T:System.Func`1 invoked to produce a lazily-initialized value when an attempt is made to retrieve P:System.Threading.ThreadLocal`1.Value without it having been previously initialized.
trackAllValues	`true` to track all values set on the instance and expose them through the P:System.Threading.ThreadLocal`1.Values property; `false` otherwise.

Exceptions

T:System.ArgumentNullException valueFactory is a null reference (Nothing in Visual Basic).

Definition at line 286 of file ThreadLocal.cs.

Member Function Documentation

◆ Dispose() [1/2]

void System.Threading.ThreadLocal< T >.Dispose ( )

Releases all resources used by the current instance of the T:System.Threading.ThreadLocal`1 class.

Implements System.IDisposable.

Definition at line 318 of file ThreadLocal.cs.

◆ Dispose() [2/2]

virtual void System.Threading.ThreadLocal< T >.Dispose ( bool disposing )

protectedvirtual

Releases the resources used by this T:System.Threading.ThreadLocal`1 instance.

Parameters

disposing A Boolean value that indicates whether this method is being called due to a call to M:System.Threading.ThreadLocal`1.Dispose.

Definition at line 327 of file ThreadLocal.cs.

◆ ToString()

override string System.Threading.ThreadLocal< T >.ToString ( )

Creates and returns a string representation of this instance for the current thread.

Returns: The result of calling M:System.Object.ToString on the P:System.Threading.ThreadLocal`1.Value.

Exceptions

T:System.ObjectDisposedException	The T:System.Threading.ThreadLocal`1 instance has been disposed.
T:System.NullReferenceException	The P:System.Threading.ThreadLocal`1.Value for the current thread is a null reference (Nothing in Visual Basic).
T:System.InvalidOperationException	The initialization function attempted to reference P:System.Threading.ThreadLocal`1.Value recursively.
T:System.MissingMemberException	No default constructor is provided and no value factory is supplied.

Definition at line 361 of file ThreadLocal.cs.

Property Documentation

◆ IsValueCreated

bool System.Threading.ThreadLocal< T >.IsValueCreated

get

Gets whether P:System.Threading.ThreadLocal`1.Value is initialized on the current thread.

Returns: true if P:System.Threading.ThreadLocal`1.Value is initialized on the current thread; otherwise false.

Exceptions

T:System.ObjectDisposedException The T:System.Threading.ThreadLocal`1 instance has been disposed.

Definition at line 214 of file ThreadLocal.cs.

◆ Value

T System.Threading.ThreadLocal< T >.Value

getset

Gets or sets the value of this instance for the current thread.

Returns: Returns an instance of the object that this ThreadLocal is responsible for initializing.

Exceptions

T:System.ObjectDisposedException	The T:System.Threading.ThreadLocal`1 instance has been disposed.
T:System.InvalidOperationException	The initialization function attempted to reference P:System.Threading.ThreadLocal`1.Value recursively.
T:System.MissingMemberException	No default constructor is provided and no value factory is supplied.

Definition at line 143 of file ThreadLocal.cs.

◆ Values

IList<T> System.Threading.ThreadLocal< T >.Values

get

Gets a list for all of the values currently stored by all of the threads that have accessed this instance.

Returns: A list for all of the values currently stored by all of the threads that have accessed this instance.

Exceptions

T:System.InvalidOperationException	Values stored by all threads are not available because this instance was initialized with the trackAllValues argument set to `false` in the call to a class constructor.
T:System.ObjectDisposedException	The T:System.Threading.ThreadLocal`1 instance has been disposed.
