Compara dos objetos 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

Parámetros

object1

IBuffer

Búfer que se va a usar para la comparación.

object2

IBuffer

Búfer que se va a usar para la comparación.

Devoluciones

Boolean

bool

True especifica que los búferes son iguales. Dos búferes son iguales si cada punto de código de uno coincide con el punto de código correspondiente en el otro.

Ejemplos

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);
