重载

GetNonZeroBytes(Byte[])	当在派生类中重写时，用加密型强随机非零值序列填充字节数组。
GetNonZeroBytes(Span<Byte>)	使用加密型强随机非零值序列填充字节范围。

GetNonZeroBytes(Byte[])

当在派生类中重写时，用加密型强随机非零值序列填充字节数组。

public:
 virtual void GetNonZeroBytes(cli::array <System::Byte> ^ data);

public:
 abstract void GetNonZeroBytes(cli::array <System::Byte> ^ data);

public virtual void GetNonZeroBytes (byte[] data);

public abstract void GetNonZeroBytes (byte[] data);

abstract member GetNonZeroBytes : byte[] -> unit
override this.GetNonZeroBytes : byte[] -> unit

abstract member GetNonZeroBytes : byte[] -> unit

Public Overridable Sub GetNonZeroBytes (data As Byte())

Public MustOverride Sub GetNonZeroBytes (data As Byte())

参数

data

Byte[]

用加密型强随机非零字节填充的数组。

示例

以下示例创建 100 个非零字节的随机序列并将其存储在 random其中。

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.

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.

Dim random() As Byte = New Byte(100) {}
'RNGCryptoServiceProvider is an implementation of an RNG
Dim rng As New RNGCryptoServiceProvider()
rng.GetNonZeroBytes(random) ' bytes in random are now random and none are zero

注解

字节数组的长度决定了生成多少个随机字节。

GetNonZeroBytes(Span<Byte>)

使用加密型强随机非零值序列填充字节范围。

public:
 virtual void GetNonZeroBytes(Span<System::Byte> data);

public virtual void GetNonZeroBytes (Span<byte> data);

abstract member GetNonZeroBytes : Span<byte> -> unit
override this.GetNonZeroBytes : Span<byte> -> unit

Public Overridable Sub GetNonZeroBytes (data As Span(Of Byte))

参数

data

Span<Byte>

要用加密型强随机非零字节填充的范围。
