RNGCryptoServiceProvider.GetNonZeroBytes Method (Byte())

 

Fills an array of bytes with a cryptographically strong sequence of random nonzero values.

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

Public Overrides Sub GetNonZeroBytes (
	data As Byte()
)

Parameters

data
Type: System.Byte()

The array to fill with a cryptographically strong sequence of random nonzero values.

Exception Condition
CryptographicException

The cryptographic service provider (CSP) cannot be acquired.

ArgumentNullException

data is null.

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

The following code 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
