LazyInitializer.EnsureInitialized<T> Method (T, Func<T>)
Initializes a target reference type by using a specified function if it hasn't already been initialized.
Assembly: mscorlib (in mscorlib.dll)
public static T EnsureInitialized<T>( ref T target, Func<T> valueFactory ) where T : class
The reference type of the reference to be initialized.
The reference of type T to initialize if it hasn't already been initialized.
- Type: System.Func<>
The function that is called to initialize the reference.
The initialized value of type T.
This method may only be used on reference types, and valueFactory may not return a null reference (Nothing in Visual Basic). To ensure initialization of value types or to allow null reference types, see other overloads of EnsureInitialized.
This method may be used concurrently by multiple threads to initialize target.
In the event that multiple threads access this method concurrently, multiple instances of T may be created, but only one will be stored into target. In such an occurrence, this method will not dispose of the objects that were not stored. If such objects must be disposed, it is up to the caller to determine if an object was not used and to then dispose of the object appropriately.
