When i am doing Deserialize of xml i am getting "There is an error in XML document (1, 41)." . Can anyone tell me about what is the issue is all about.
public static T DeserializeFromXml<T>(string xml)
{
T result;
XmlSerializer ser = new XmlSerializer(typeof(T));
using (TextReader tr = new StringReader(xml))
{
result = (T)ser.Deserialize(tr);
}
return result;
}
I use this function to do it.
<?xml version='1.0' encoding='utf-16'?>

Agreed with the answer from sll, but experienced another hurdle which was having specified a namespace in the attributes, when receiving the return xml that namespace wasn't included and thus failed finding the class.
i had to find a workaround to specifying the namespace in the attribute and it worked.
ie.
[Serializable()]
[XmlRoot("Patient", Namespace = "http://www.xxxx.org/TargetNamespace")]
public class Patient
generated
<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.xxxx.org/TargetNamespace">
but I had to change it to
[Serializable()]
[XmlRoot("Patient")]
public class Patient
which generated to
<Patient xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
This solved my problem, hope it helps someone else.
On a WEC7 project I'm working on, I got a similar error. The file I was serializing in was serialized out from an array of objects, so I figured the XML was fine. Also, I have had this working for a few previous classes, so it was quite a puzzle.
Then I noticed in my earlier work that every class that I was serializing/deserializing had a default constructor. That was missing in my failed case so I added it and and voila... it worked fine.
I seem to remember reading somewhere that this was required. I guess it is.
In my case I had a float value expected where xml had a null value so be sure to search for float and int data type in your xsd map
I had the same thing. All came down to a "d" instead of a "D" in a tag name in the schema.
First check the variables declared using proper Datatypes. I had a same problem then I have checked, by mistake I declared SAPUser as int datatype so that the error occurred. One more thing XML file stores its data using concept like array but its first index starts having +1. e.g. if error is in(7,2) then check for 6th line always.....
