Lazy(Of T) Class
Provides support for lazy initialization.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
The Lazy(Of T) type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Lazy(Of T) | Initializes a new instance of the Lazy(Of T) class. When lazy initialization occurs, the default constructor of the target type is used. |
![]() | Lazy(Of T)(Boolean) | Initializes a new instance of the Lazy(Of T) class. When lazy initialization occurs, the default constructor of the target type and the specified initialization mode are used. |
![]() | Lazy(Of T)(Func(Of T)) | Initializes a new instance of the Lazy(Of T) class. When lazy initialization occurs, the specified initialization function is used. |
![]() | Lazy(Of T)(LazyThreadSafetyMode) | Initializes a new instance of the Lazy(Of T) class that uses the default constructor of T and the specified thread safety mode. |
![]() | Lazy(Of T)(Func(Of T), Boolean) | Initializes a new instance of the Lazy(Of T) class. When lazy initialization occurs, the specified initialization function and initialization mode are used. |
![]() | Lazy(Of T)(Func(Of T), LazyThreadSafetyMode) | Initializes a new instance of the Lazy(Of T) class that uses the specified initialization function and thread safety mode. |
| Name | Description | |
|---|---|---|
![]() | IsValueCreated | Gets a value that indicates whether a value has been created for this Lazy(Of T) instance. |
![]() | Value | Gets the lazily initialized value of the current Lazy(Of T) instance. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Creates and returns a string representation of the Lazy(Of T).Value property for this instance. (Overrides Object.ToString.) |
Lazy initialization occurs the first time the Lazy(Of T).Value property is accessed.
Use an instance of Lazy(Of T) to defer the creation of a large or resource-intensive object or the execution of a resource-intensive task, particularly when such creation or execution might not occur during the lifetime of the program.
