Property Value

Type: T

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

Exception Condition

The ThreadLocal<T> instance has been disposed.


The initialization function attempted to reference Value recursively.


No default constructor is provided and no value factory is supplied.

If this instance was not previously initialized for the current thread, accessing Value will attempt to initialize it. If an initialization function was supplied during the construction, that initialization will happen by invoking the function to retrieve the initial value for Value. Otherwise, the default value of will be used. If an exception is thrown, that exception is cached and thrown on each subsequent access of the property.
