Question

I have some xml files and I am trying to deserialize as below in the given code.

using (StreamReader srFileContent = new StreamReader(filePath))  
{
    XmlSerializer serializer = new XmlSerializer(typeof(messageType));   
    messageType objMessage = (messageType)serializer.Deserialize(srFileContent);  
}

Here file locate at filePath does not contains the following lines

<?xml version="1.0"?>
<message xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">

and thats why I’m getting the error. Can u help me how to add this lines runtime before deserialize the stream of given file.

Error is given below:

System.InvalidOperationException: There is an error in XML document

You will have to look at the base exception to find out the problem. The exception caught probably contains 4 or more inner exceptions.

EG:

try
{
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.GetBaseException());
}
