Deserialization error in XML document(1,1)

I have an XML file that I deserialize, the funny part is the XML file is the was s开发者_StackOverflow中文版erialized using the following code:

enter code here
var serializer = new XmlSerializer(typeof(CommonMessage));
var writer = new StreamWriter("OutPut.txt");
serializer.Serialize(writer, commonMessage);
writer.Close();

And i m trying to deserialized it again to check if the output match the input. anyhow here is my code to deserialize:

var serializer = new XmlSerializer(typeof(CommonMessage));
var reader = new StringReader(InputFileName);
CommonMessage commonMessage = (CommonMessage)serializer.Deserialize(reader);

Replace StringReader with StreamReader and it will work fine. StringReader reads value from the string (which is file name in your case).

I just had the same error message but different error source. In case someone has the same problem like me. I chopped off the very first char of my xml string by splitting strings. And the xml string got corrupted:

"?xml version="1.0" encoding="utf-16"?> ..." // my error
"<?xml version="1.0" encoding="utf-16"?> ..." // correct

(1,1) means basically first char of the first line is incorrect and the string can't be deserialized.

include in your CommonMessage class the XmlRoot element tag with your xmlroot eg:[XmlRoot("UIIVerificationResponse")]

You should disable the order mark in the StreamWriter constructor like this:

UTF8Encoding(false)

Full sample:

        using (MemoryStream stream = new MemoryStream())
        using (StreamWriter writer = new StreamWriter(stream, new UTF8Encoding(false)))
        {
            xmlSerializer.Serialize(writer, objectToSerialize, ns);

            return Encoding.UTF8.GetString(stream.ToArray());
        }
