Encoding and decoding base64 data (XAML)

The following example shows how to perform Base64 encoding and decoding.

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);
