RandomNumberGenerator Class

RandomNumberGenerator Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents the abstract class from which all implementations of cryptographic random number generators derive.

System.Object
  System.Security.Cryptography.RandomNumberGenerator
    System.Security.Cryptography.RNGCryptoServiceProvider

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public abstract class RandomNumberGenerator

The RandomNumberGenerator type exposes the following members.

  NameDescription
Protected methodRandomNumberGeneratorInitializes a new instance of RandomNumberGenerator.
Top

  NameDescription
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetBytesWhen overridden in a derived class, fills an array of bytes with a cryptographically strong, random sequence of values.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Cryptographic random number generators create cryptographically strong random values.

Application code does not directly use this class. This abstract class is provided as the base class for all cryptographic random number generators.

For an implementation of a cryptographic random number generator, use the derived class RNGCryptoServiceProvider.
