The Distribution type exposes the following members.
Constructors

Distribution | Called from constructors in derived classes to initialize the Distribution class. |

Properties

Methods
| Name | Description | |
|---|---|---|

Equals | 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 it is reclaimed by garbage collection. (Inherited from Object.) |
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
GetRangeValue | Returns a value between 0 and 1 that represents a point on the distribution curve. |
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
Initialize | Initializes this instance by using the provided initialization information. |
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
OnGetRangeValue | Returns a value between 0 and 1 and represents a point on the distribution curve. |
|
OnInitialize | Initializes a distribution when it is overridden in a derived class. |
|
OnSetInputValues | Implements custom behavior that is executed when the input values for a distribution are set. |
|
OnValidateInputs | Validates that all the required input properties for the distribution have been set when they are overridden in a derived class. |
|
SetExtensionHandle | Sets the extension handle. |
|
SetInputValues | Sets input values for a distribution. This method cannot be overridden. |
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
|
ValidateInputs | Validates that all the required input properties for the distribution have been set. |

Remarks
Each 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 to work with the object at design time, 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.
