RandomNumberGenerator.GetNonZeroBytes Method

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 virtual void GetNonZeroBytes(
	byte[] data
)

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.

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.
