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)

abstract GetNonZeroBytes : 
        data:byte[] -> unit  
override GetNonZeroBytes : 
        data:byte[] -> unit


Type: System.Byte[]

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


The cryptographic service provider (CSP) cannot be acquired.


data is a null reference (Nothing in Visual Basic).

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.

No code example is currently available or this language may not be supported.
