Constructor & Destructor Documentation

◆ Lazy() [1/4]

System.Lazy< T >.Lazy ( )

Initializes a new instance of the T:System.Lazy`1 class. When lazy initialization occurs, the default constructor of the target type is used.

Definition at line 128 of file Lazy.cs.

◆ Lazy() [2/4]

System.Lazy< T >.Lazy ( Func< T > valueFactory )

Initializes a new instance of the T:System.Lazy`1 class. When lazy initialization occurs, the specified initialization function is used.

Parameters

valueFactory The delegate that is invoked to produce the lazily initialized value when it is needed.

Exceptions

T:System.ArgumentNullException valueFactory is null.

Definition at line 138 of file Lazy.cs.

◆ Lazy() [3/4]

System.Lazy< T >.Lazy ( LazyThreadSafetyMode mode )

Initializes a new instance of the T:System.Lazy`1 class that uses the default constructor of T and the specified thread-safety mode.

Parameters

mode	One of the enumeration values that specifies the thread safety mode.

Exceptions

T:System.ArgumentOutOfRangeException mode contains an invalid value.

Definition at line 157 of file Lazy.cs.

◆ Lazy() [4/4]

System.Lazy< T >.Lazy	(	Func< T >	valueFactory,
		LazyThreadSafetyMode	mode
	)

Initializes a new instance of the T:System.Lazy`1 class that uses the specified initialization function and thread-safety mode.

Parameters

valueFactory	The delegate that is invoked to produce the lazily initialized value when it is needed.
mode	One of the enumeration values that specifies the thread safety mode.

Exceptions

T:System.ArgumentOutOfRangeException	mode contains an invalid value.
T:System.ArgumentNullException	valueFactory is `null`.

Definition at line 182 of file Lazy.cs.

Member Function Documentation

◆ Lazy?() [1/2]

System.Lazy< T >.Lazy? ( bool isThreadSafe )

Initializes a new instance of the T:System.Lazy`1 class. When lazy initialization occurs, the default constructor of the target type and the specified initialization mode are used.

Parameters

isThreadSafe true to make this instance usable concurrently by multiple threads; false to make the instance usable by only one thread at a time.

Definition at line 147 of file Lazy.cs.

◆ Lazy?() [2/2]

System.Lazy< T >.Lazy?	(	Func< T >	valueFactory,
		bool	isThreadSafe
	)

Initializes a new instance of the T:System.Lazy`1 class. When lazy initialization occurs, the specified initialization function and initialization mode are used.

Parameters

valueFactory	The delegate that is invoked to produce the lazily initialized value when it is needed.
isThreadSafe	`true` to make this instance usable concurrently by multiple threads; `false` to make this instance usable by only one thread at a time.

Exceptions

T:System.ArgumentNullException valueFactory is null.

Definition at line 169 of file Lazy.cs.

◆ ToString()

override string System.Lazy< T >.ToString ( )

Creates and returns a string representation of the P:System.Lazy`1.Value property for this instance.

Returns: The result of calling the M:System.Object.ToString method on the P:System.Lazy`1.Value property for this instance, if the value has been created (that is, if the P:System.Lazy`1.IsValueCreated property returns true). Otherwise, a string indicating that the value has not been created.

Exceptions

T:System.NullReferenceException The P:System.Lazy`1.Value property is null.

Definition at line 217 of file Lazy.cs.

Property Documentation

◆ IsValueCreated

bool System.Lazy< T >.IsValueCreated

get

Gets a value that indicates whether a value has been created for this T:System.Lazy`1 instance.

Returns: true if a value has been created for this T:System.Lazy`1 instance; otherwise, false.

Definition at line 86 of file Lazy.cs.

◆ Value

T System.Lazy< T >.Value

get

Gets the lazily initialized value of the current T:System.Lazy`1 instance.

Returns: The lazily initialized value of the current T:System.Lazy`1 instance.

Exceptions

T:System.MemberAccessException	The T:System.Lazy`1 instance is initialized to use the default constructor of the type that is being lazily initialized, and permissions to access the constructor are missing.
T:System.MissingMemberException	The T:System.Lazy`1 instance is initialized to use the default constructor of the type that is being lazily initialized, and that type does not have a public, parameterless constructor.
T:System.InvalidOperationException	The initialization function tries to access P:System.Lazy`1.Value on this instance.
