| GetNonZeroBytes(Byte[]) |
Fills an array of bytes with a cryptographically strong sequence of random nonzero values. |
| GetNonZeroBytes(Span<Byte>) |
Fills a byte span with a cryptographically strong random sequence of nonzero values. |

Fills an array of bytes with a cryptographically strong sequence of random nonzero values.
public:
override void GetNonZeroBytes(cli::array <System::Byte> ^ data);public override void GetNonZeroBytes(byte[] data);override this.GetNonZeroBytes : byte[] -> unitPublic Overrides Sub GetNonZeroBytes (data As Byte())Parameters
- data
- Byte[]
The array to fill with a cryptographically strong sequence of random nonzero values.
Exceptions
The cryptographic service provider (CSP) cannot be acquired.
data is null.
Examples
The following code example creates a random sequence of 100 nonzero bytes and stores it in random.
array<Byte>^ random = gcnew array<Byte>(100);
RandomNumberGenerator^ rng = RandomNumberGenerator::Create();
rng->GetNonZeroBytes( random ); // The array is now filled with cryptographically strong random bytes, and none are zero.
byte[] random = new byte[100];
using (RandomNumberGenerator rng = RandomNumberGenerator.Create())
{
rng.GetNonZeroBytes(random); // The array is now filled with cryptographically strong random bytes, and none are zero.
}
Dim random() As Byte = New Byte(100) {}
Using rng As RandomNumberGenerator = RandomNumberGenerator.Create()
rng.GetNonZeroBytes(random) ' bytes in random are now random and none are zero
End Using
Remarks
The length of the byte array determines how many cryptographically strong random nonzero bytes are produced.
