Codieren und Decodieren von Daten

Dieser Beispielcode zeigt, wie Base64- und Hexadezimaldaten in einer Universelle Windows-Plattform-App (UWP) codiert und decodiert werden.

public void EncodeDecodeBase64()
{
    // Define a Base64 encoded string.
    String strBase64 = "uiwyeroiugfyqcajkds897945234==";

    // Decoded the string from Base64 to binary.
    IBuffer buffer = CryptographicBuffer.DecodeFromBase64String(strBase64);

    // Encode the buffer back into a Base64 string.
    String strBase64New = CryptographicBuffer.EncodeToBase64String(buffer);
}

public void EncodeDecodeHex()
{
    // Define a hexadecimal string.
    String strHex = "30310AFF";

    // Decode a hexadecimal string to binary.
    IBuffer buffer = CryptographicBuffer.DecodeFromHexString(strHex);

    // Encode the buffer back into a hexadecimal string.
    String strHexNew = CryptographicBuffer.EncodeToHexString(buffer);
}
