Remarks
Cryptographic random number generators create cryptographically strong random values.
Using the static members of this class is the preferred way to generate random values.
To create a random number generator, call the Create() method. This is preferred over calling the constructor of the derived class RNGCryptoServiceProvider, which is not available on all platforms.
Constructors
RandomNumberGenerator() |
Initializes a new instance of RandomNumberGenerator. |
Methods
Create() |
Creates an instance of the default implementation of a cryptographic random number generator that can be used to generate random data. |
Create(String) |
Obsolete.
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) |
Fill(Span<Byte>) |
Fills a span with cryptographically strong random bytes. |
GetBytes(Byte[]) |
When overridden in a derived class, fills an array of bytes with a cryptographically strong random sequence of values. |
GetBytes(Byte[], Int32, Int32) |
Fills the specified byte array with a cryptographically strong random sequence of values. |
GetBytes(Int32) |
Creates an array of bytes with a cryptographically strong random sequence of values. |
GetBytes(Span<Byte>) |
Fills a span with cryptographically strong random bytes. |
GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
GetHexString(Int32, Boolean) |
Creates a string filled with cryptographically random hexadecimal characters. |
GetHexString(Span<Char>, Boolean) |
Fills a buffer with cryptographically random hexadecimal characters. |
GetInt32(Int32) |
Generates a random integer between 0 (inclusive) and a specified exclusive upper bound using a cryptographically strong random number generator. |
GetInt32(Int32, Int32) |
Generates a random integer between a specified inclusive lower bound and a specified exclusive upper bound using a cryptographically strong random number generator. |
GetItems<T>(ReadOnlySpan<T>, Int32) |
Creates an array populated with items chosen at random from choices. |
GetItems<T>(ReadOnlySpan<T>, Span<T>) |
Fills the elements of a specified span with items chosen at random from the provided set of choices. |
GetNonZeroBytes(Byte[]) |
When overridden in a derived class, fills an array of bytes with a cryptographically strong random sequence of nonzero values. |
GetNonZeroBytes(Span<Byte>) |
Fills a byte span with a cryptographically strong random sequence of nonzero values. |
GetString(ReadOnlySpan<Char>, Int32) |
Creates a string populated with characters chosen at random from choices. |
GetType() |
Gets the Type of the current instance. (Inherited from Object) |
MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
Shuffle<T>(Span<T>) |
Performs an in-place shuffle of a span using cryptographically random number generation. |
ToString() |
Returns a string that represents the current object. (Inherited from Object) |
