Définition

Espace de noms:

Windows.Security.Cryptography

Compare deux objets IBuffer .

public:
 static bool Compare(IBuffer ^ object1, IBuffer ^ object2);

 static bool Compare(IBuffer const& object1, IBuffer const& object2);

public static bool Compare(IBuffer object1, IBuffer object2);

function compare(object1, object2)

Public Shared Function Compare (object1 As IBuffer, object2 As IBuffer) As Boolean

Paramètres

object1

IBuffer

Mémoire tampon à utiliser pour la comparaison.

object2

IBuffer

Mémoire tampon à utiliser pour la comparaison.

Retours

Boolean

bool

True spécifie que les mémoires tampons sont égales. Deux mémoires tampons sont égales si chaque point de code dans l’un correspond au point de code correspondant dans l’autre.

Exemples

public void CompareBuffers()
{
    // Create a hexadecimal string.
    String strHex = "30310aff";

    // Create a Base64 string that is equivalent to strHex.
    String strBase64v1 = "MDEK/w==";

    // Create a Base64 string that is not equivalent to strHex.
    String strBase64v2 = "KEDM/w==";

    // Decode strHex to a buffer.
    IBuffer buff1 = CryptographicBuffer.DecodeFromHexString(strHex);

    // Decode strBase64v1 to a buffer.
    IBuffer buff2 = CryptographicBuffer.DecodeFromBase64String(strBase64v1);

    // Decode strBase64v2 to a buffer.
    IBuffer buff3 = CryptographicBuffer.DecodeFromBase64String(strBase64v2);

    // Compare the hexadecimal-decoded buff1 to the Base64-decoded buff2.
    // The code points in the two buffers are equal, and the Boolean value
    // is true.
    Boolean bVal_1 = CryptographicBuffer.Compare(buff1, buff2);

    // Compare the hexadecimal-decoded buff1 to the Base64-decoded buff3.
    // The code points in the two buffers are not equal, and the Boolean value
    // is false.
    Boolean bVal_2 = CryptographicBuffer.Compare(buff1, buff3);
