The DistributionAttribute type exposes the following members.

Constructors

	Name	Description
	DistributionAttribute	Initializes a new instance of the DistributionAttribute class by using the provided designer type.

Properties

	Name	Description
	DesignerType	Gets the Type of the designer.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	_Attribute.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	_Attribute.GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	_Attribute.GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	_Attribute.Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

Each standard numeric data generator has a Distribution property. The user can specify that the property generates data that approximates a statistical distribution curve. The standard distribution options are as follows: Uniform, Normal, Normal Inverse, Exponential, and Exponential Inverse.

If the standard distributions are insufficient, you can create a custom distribution. To create a custom distribution, you must create a class that implements IDistribution or inherits from Distribution. You identify the class as a distribution by decorating it with DistributionAttribute.

You can create a custom designer for a custom distribution, or you can use the DefaultDistributionDesigner.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
