CryptographicBuffer.Compare(IBuffer, IBuffer) 方法

定义

命名空间:

Windows.Security.Cryptography

比较两个 IBuffer 对象。

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

参数

object1

IBuffer

要用于比较的缓冲区。

object2

IBuffer

要用于比较的缓冲区。

返回

Boolean

bool

True 指定缓冲区相等。 如果一个缓冲区中的每个码位与另一个中的相应码位匹配，则两个缓冲区相等。

示例

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);
