.NET Framework (current version)
 

Initializes the ThreadLocal<T> instance with the specified valueFactory function and a flag that indicates whether all values are accessible from any thread.

Namespace:   System.Threading
Assembly:  mscorlib (in mscorlib.dll)

public ThreadLocal(
	Func<T> valueFactory,
	bool trackAllValues
)

Parameters

valueFactory
Type: System.Func<T>

The Func<TResult> invoked to produce a lazily-initialized value when an attempt is made to retrieve Value without it having been previously initialized.

trackAllValues
Type: System.Boolean

true to track all values set on the instance and expose them through the Values property; false otherwise.

Exception Condition

valueFactory is a null reference (Nothing in Visual Basic).

If trackAllValues is false, only the value of this instance for the current thread is accessible. Attempting to use the Values property to retrieve all values throws an InvalidOperationException exception.
