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 abstract void GetNonZeroBytes (
	byte[] data
)
public abstract void GetNonZeroBytes (
	byte[] data
)
public abstract function GetNonZeroBytes (
	data : byte[]
)
Not applicable.

Parameters

data

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.

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.
