CryptographicBuffer.CreateFromByteArray(Byte[]) 方法

定义

命名空间:

Windows.Security.Cryptography

从输入字节数组创建缓冲区。

public:
 static IBuffer ^ CreateFromByteArray(Platform::Array <byte> ^ value);

 static IBuffer CreateFromByteArray(winrt::array_view <byte> const& value);

public static IBuffer CreateFromByteArray(byte[] value);

function createFromByteArray(value)

Public Shared Function CreateFromByteArray (value As Byte()) As IBuffer

参数

value

Byte[]

byte[]

用于创建缓冲区的字节数组。

返回

IBuffer

输出缓冲区。

示例

public void ByteArrayCopy()
{
    // Initialize a byte array.
    byte[] arrByte = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

    // Create a buffer from the byte array.
    IBuffer buffer = CryptographicBuffer.CreateFromByteArray(arrByte);

    // Encode the buffer into a hexadecimal string (for display);
    String strHex = CryptographicBuffer.EncodeToHexString(buffer);

    // Copy the buffer back into a new byte array.
    byte[] arrByteNew;
    CryptographicBuffer.CopyToByteArray(buffer, out arrByteNew);
}
