RNGCryptoServiceProvider::GetNonZeroBytes Method (array<Byte>^)
.NET Framework (current version)
Fills an array of bytes with a cryptographically strong sequence of random nonzero values.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- data
-
Type:
array<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.
array<Byte>^ random = gcnew array<Byte>(100); //RNGCryptoServiceProvider is an implementation of a random number generator. RNGCryptoServiceProvider^ rng = gcnew RNGCryptoServiceProvider; rng->GetNonZeroBytes( random ); // The array is now filled with cryptographically strong random bytes, and none are zero.
