Base64 decode in C# or Java

Question

I have a Base64-encoded object with the following header:

application/x-xfdl;content-encoding=\"asc-gzip\"

What is the best way to proceed

Answer 1

Copied from elsewhere, for Base64 I link to commons-codec-1.6.jar:

public static String decode(String input) throws Exception {
    byte[] bytes = Base64.decodeBase64(input);
    BufferedReader in = new BufferedReader(new InputStreamReader(
            new GZIPInputStream(new ByteArrayInputStream(bytes))));
    StringBuffer buffer = new StringBuffer();
    char[] charBuffer = new char[1024]; 
    while(in.read(charBuffer) != -1) {
        buffer.append(charBuffer);
    }
    return buffer.toString();
}
