EnsureInitialized< T >() [1/4]

static T System.Threading.LazyInitializer.EnsureInitialized< T > ( ref T  target )

static

Initializes a target reference type with the type's default constructor if it hasn't already been initialized.

Parameters

target

A reference of type T to initialize if it has not already been initialized.

Template Parameters

T	The type of the reference to be initialized.

Returns

The initialized reference of type T .

Exceptions

T:System.MemberAccessException	Permissions to access the constructor of type T were missing.
T:System.MissingMemberException	Type T does not have a default constructor.

EnsureInitialized< T >() [2/4]

static T System.Threading.LazyInitializer.EnsureInitialized< T > ( ref T  target, Func< T >  valueFactory  )

static

Initializes a target reference type by using a specified function if it hasn't already been initialized.

Parameters

target	The reference of type T to initialize if it hasn't already been initialized.
valueFactory	The function that is called to initialize the reference.

Template Parameters

T	The reference type of the reference to be initialized.

Returns

The initialized value of type T .

Exceptions

T:System.MissingMemberException	Type T does not have a default constructor.
T:System.InvalidOperationException	valueFactory returned null (Nothing in Visual Basic).

EnsureInitialized< T >() [3/4]

static T System.Threading.LazyInitializer.EnsureInitialized< T > ( ref T  target, ref bool  initialized, ref object  syncLock  )

static

Initializes a target reference or value type with its default constructor if it hasn't already been initialized.

Parameters

target	A reference or value of type T to initialize if it hasn't already been initialized.
initialized	A reference to a Boolean value that determines whether the target has already been initialized.
syncLock	A reference to an object used as the mutually exclusive lock for initializing target . If syncLock is null, a new object will be instantiated.

Template Parameters

T	The type of the reference to be initialized.

Returns

The initialized value of type T .

Exceptions

T:System.MemberAccessException	Permissions to access the constructor of type T were missing.
T:System.MissingMemberException	Type T does not have a default constructor.

EnsureInitialized< T >() [4/4]

static T System.Threading.LazyInitializer.EnsureInitialized< T > ( ref T  target, ref bool  initialized, ref object  syncLock, Func< T >  valueFactory  )

static

Initializes a target reference or value type by using a specified function if it hasn't already been initialized.

Parameters

target	A reference or value of type T to initialize if it hasn't already been initialized.
initialized	A reference to a Boolean value that determines whether the target has already been initialized.
syncLock	A reference to an object used as the mutually exclusive lock for initializing target . If syncLock is null, a new object will be instantiated.
valueFactory	The function that is called to initialize the reference or value.

Template Parameters

T	The type of the reference to be initialized.

Returns

The initialized value of type T .

Exceptions

T:System.MemberAccessException	Permissions to access the constructor of type T were missing.
T:System.MissingMemberException	Type T does not have a default constructor.
