CryptographicBuffer.CopyToByteArray(IBuffer, Byte[]) CryptographicBuffer.CopyToByteArray(IBuffer, Byte[]) CryptographicBuffer.CopyToByteArray(IBuffer, Byte[]) CryptographicBuffer.CopyToByteArray(IBuffer, Byte[]) CryptographicBuffer.CopyToByteArray(IBuffer, Byte[]) Method

Definition

Copies a buffer to an array of bytes.

public : static void CopyToByteArray(IBuffer buffer, Byte[] value)
static void CopyToByteArray(IBuffer buffer, Byte[] const& value) const;
public static void CopyToByteArray(IBuffer buffer, Byte[] value)
Public Shared Sub CopyToByteArray(buffer As IBuffer, value As Byte[])
Windows.Security.Cryptography.CryptographicBuffer.copyToByteArray(buffer, value);

Parameters

buffer
IBuffer IBuffer IBuffer

Input buffer.

value
Byte[] Byte[] Byte[]

An array of bytes that contains the values copied from the input buffer. You must declare the array before calling this method and pass it by using the ref keyword. If the buffer for the input parameter is empty, then the value parameter will be returned as NULL.

Examples

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);
