How to convert byte array to xml?

I have a byte stream like this:

byte[] response =
        {
            69, 90, 69, 45, 88, 77, 76, 45, 77, 115, 103, 48, 50, 60, 77, 101, 115, 115, 97, 103, 101, 62, 13, 10, 32,
            32, 60, 72, 101, 97, 100, 101, 114, 62, 13, 10, 32, 32, 32, 32, 60, 77, 101, 115, 115, 97, 103, 101, 68,
            97, 116, 101, 62, 50, 48, 49, 48, 48, 51, 50, 52, 60, 47, 77, 101, 115, 115, 97, 103, 101, 68, 97, 116,
            101, 62, 13, 10, 32, 32, 32, 32, 60, 77, 101, 115, 115, 97, 103, 101, 84, 105, 109, 101, 62, 49, 57, 50,
            56, 48, 54, 60, 47, 77, 101, 115, 115, 97, 103, 101, 84, 105, 109, 101, 62, 13, 10, 32, 32, 60, 47, 72,
            101, 97, 100, 101, 114, 62, 13, 10, 32, 32, 60, 66, 111, 100, 121, 62, 13, 10, 32, 32, 32, 32, 60, 84,
            114, 97, 110, 115, 97, 99, 116, 105, 111, 110, 73, 68, 62, 51, 51, 50, 53, 50, 55, 60, 47, 84, 114, 97,
            110, 115, 97, 99, 116, 105, 111, 110, 73, 68, 62, 13, 10, 32, 32, 32, 32, 60, 84, 114, 97, 110, 115, 97,
            99, 116, 105, 111, 110, 78, 117, 109, 98, 101, 114, 62, 49, 50, 49, 48, 52, 55, 48, 60, 47, 84, 114, 97,
            110, 115, 97, 99, 116, 105, 111, 110, 78, 117, 109, 98, 101, 114, 62, 13, 10, 32, 32, 32, 32, 60, 80,
            104, 111, 110, 101, 78, 117, 109, 98, 101, 114, 62, 54, 51, 57, 57, 57, 57, 57, 57, 57, 57, 57, 57, 60,
            47, 80, 104, 111, 110, 101, 78, 117, 109, 98, 101, 114, 62, 13, 10, 32, 32, 32, 32, 60, 65, 109, 111,
            117, 110, 116, 62, 48, 48, 48, 48, 48, 48, 50, 53, 48, 48, 60, 47, 65, 109, 111, 117, 110, 116, 62, 13,
            10, 32, 32, 32, 32, 60, 82, 101, 115, 117, 108, 116, 62, 48, 51, 60, 47, 82, 101, 115, 117, 108, 116, 62,
            13, 10, 32, 32, 60, 47, 66, 111, 100, 121, 62, 13, 10, 60, 47, 77, 101, 115, 115, 97, 103, 101, 62
        };

I want to extract the xml out of it. Tried the following:

XmlDocument doc2 = new XmlDocument();
        MemoryStream ms = new MemoryStream(response);
        doc2.Load(ms);

But got an exception like:

An unhandled exception of type 'System.Xml.XmlException' occurred in System.Xml.dll

Additional information: Data at the root level is invalid. Line 1, position 1.

I'm really new to this xml stuff, what should doc2.load() method do? will it create any xml file which I can read later, will it be just a in memory collection?

Solution

The problem is that your byte [] array represents a string that has some non-XML characters at the beginning. If I do

string s;
using (var ms = new MemoryStream(response))
using (var reader = new StreamReader(ms))
{
    s = reader.ReadToEnd();

    Console.WriteLine(s);
}

I see

EZE-XML-Msg02<Message>
  <Header>
    <MessageDate>20100324</MessageDate>
    <MessageTime>192806</MessageTime>
  </Header>
  <Body>
    <TransactionID>332527</TransactionID>
    <TransactionNumber>1210470</TransactionNumber>
    <PhoneNumber>639999999999</PhoneNumber>
    <Amount>0000002500</Amount>
    <Result>03</Result>
  </Body>
</Message>

The EZE-XML-Msg02 has to be removed first. The best way to do this would be not to store it in the XML in the first place. But if you somehow cannot prevent it from being included in the XML, you could do:

XmlDocument doc2 = new XmlDocument();
using (var ms = new MemoryStream(response))
using (var reader = new StreamReader(ms))
{
    while (!reader.EndOfStream && reader.Peek() > -1 && (char)reader.Peek() != '<')
        reader.Read();
    if (!reader.EndOfStream)
        doc2.Load(reader);
}
