RandomNumberGenerator Class
Represents the abstract class from which all implementations of cryptographic random number generators derive.
System.Security.Cryptography::RandomNumberGenerator
System.Security.Cryptography::RNGCryptoServiceProvider
Assembly: mscorlib (in mscorlib.dll)
The RandomNumberGenerator type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | Create() | When overridden in a derived class, creates an instance of the default implementation of a cryptographic random number generator that can be used to generate random data. |
![]() ![]() | Create(String) | When overridden in a derived class, creates an instance of the specified implementation of a cryptographic random number generator. |
![]() | Dispose() | When overridden in a derived class, releases all resources used by the current instance of the RandomNumberGenerator class. |
![]() | Dispose(Boolean) | When overridden in a derived class, releases the unmanaged resources used by the RandomNumberGenerator and optionally releases the managed resources. |
![]() | 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 it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetBytes | When overridden in a derived class, fills an array of bytes with a cryptographically strong random sequence of values. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetNonZeroBytes | When overridden in a derived class, fills an array of bytes with a cryptographically strong random sequence of nonzero values. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns 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.
