RNGCryptoServiceProvider.GetNonZeroBytes Method

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

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

public override void GetNonZeroBytes (
	byte[] data
)
public void GetNonZeroBytes (
	byte[] data
)
public override function GetNonZeroBytes (
	data : byte[]
)

Parameters

data

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

Exception typeCondition

CryptographicException

The cryptographic service provider (CSP) cannot be acquired.

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.

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.

ubyte random[] = new ubyte[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.
