RandomNumberGenerator.GetNonZeroBytes Method (Byte())

 

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

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

Public Overridable Sub GetNonZeroBytes (
	data As Byte()
)

Parameters

data
Type: System.Byte()

The array to fill with cryptographically strong random nonzero bytes.

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

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

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
