Definition

Overloads

GetNonZeroBytes(Byte[]) GetNonZeroBytes(Byte[]) GetNonZeroBytes(Byte[]) GetNonZeroBytes(Byte[])

When overridden in a derived class, fills an array of bytes with a cryptographically strong random sequence of nonzero values.

GetNonZeroBytes(Byte[]) GetNonZeroBytes(Byte[]) GetNonZeroBytes(Byte[]) GetNonZeroBytes(Byte[])

When overridden in a derived class, fills an array of bytes with a cryptographically strong random sequence of nonzero values.

public:
 virtual void GetNonZeroBytes(cli::array <System::Byte> ^ data);
public virtual void GetNonZeroBytes (byte[] data);
abstract member GetNonZeroBytes : byte[] -> unit
override this.GetNonZeroBytes : byte[] -> unit
Public Overridable Sub GetNonZeroBytes (data As Byte())
Parameters
data
Byte[]

The array to fill with cryptographically strong random nonzero bytes.

Examples

The following example creates a random sequence of 100 nonzero bytes and stores it in random.

array<Byte>^ random = gcnew array<Byte>(100);
//RNGCryptoServiceProvider is an implementation of a random number generator.
RNGCryptoServiceProvider^ rng = gcnew RNGCryptoServiceProvider;
rng->GetNonZeroBytes( random ); // The array is now filled with cryptographically strong random bytes, and none are zero.
byte[] random = new Byte[100];
//RNGCryptoServiceProvider is an implementation of a random number generator.
RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
rng.GetNonZeroBytes(random); // The array is now filled with cryptographically strong random bytes, and none are zero.
Dim random() As Byte = New Byte(100) {}
'RNGCryptoServiceProvider is an implementation of an RNG
Dim rng As New RNGCryptoServiceProvider()
rng.GetNonZeroBytes(random) ' bytes in random are now random and none are zero

Remarks

The length of the byte array determines how many random bytes are produced.
