Trying to serialize C# object and store as XML Datatype in Sql Server 2005

Question

using
if (Obj != null)
               MemoryStream stream = new MemoryStream();
               StreamWriter writer = new StreamWriter(stream);
               XmlSerializer x = new XmlSerializer(Obj.GetType());
               x.Serialize(writer, Obj);
               writer.Close();
               byte[] arr = stream.GetBuffer();
               return Encoding.UTF8.GetString(arr).Trim();
The object looks like
    public class CorporateBondSec : BaseSecurity
        public double coupon; // CPN
        public string couponType; // CPN_TYPE
        public int couponFreq; // CPN_FREQ
        public string floater; // FLOATER
        public int resetFreq; //REFIX_FREQ
        public DateTime resetDate; //NXT_REFIX_DT              
        public DateTime firstCpnDate; //FIRST_CPN_DT
XML looks like
'<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<CorporateBondSec xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">\r\n  <coupon>8</coupon>\r\n  <couponType>FIXED</couponType>\r\n  <couponFreq>2</couponFreq>\r\n  <floater>N</floater>\r\n  <resetFreq>0</resetFreq>\r\n  <resetDate>0001-01-01T00:00:00</resetDate>\r\n  <firstCpnDate>0001-01-01T00:00:00</firstCpnDate>\r\n</CorporateBondSec>'
Error from SQL
Msg 9413, Level 16, State 1, Procedure procSecuritiesInsert, Line 0
XML parsing: line 1, character 15, A string literal was expected
I have also tried
XmlSerializer x = new XmlSerializer(Obj.GetType());
System.Text.StringBuilder builder = new System.Text.StringBuilder();
x.Serialize(XmlWriter.Create(builder), Obj);
return builder.ToString();
That gives me an XML
'<?xml version=\"1.0\" encoding=\"utf-16\"?>
<CorporateBondSec xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">
<coupon>8</coupon>
<couponType>FIXED</couponType>
<couponFreq>2</couponFreq>
<floater>N</floater>
<resetFreq>0</resetFreq>
<resetDate>0001-01-01T00:00:00</resetDate>
<firstCpnDate>0001-01-01T00:00:00</firstCpnDate>
</CorporateBondSec>'

Tony,
this is how your XML should look like.
Code Snippet
'<?xml version="1.0" encoding="utf-16"?>
<CorporateBondSec xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<coupon>8</coupon>
<couponType>FIXED</couponType>
<couponFreq>2</couponFreq>
<floater>N</floater>
<resetFreq>0</resetFreq>
<resetDate>0001-01-01T00:00:00</resetDate>
<firstCpnDate>0001-01-01T00:00:00</firstCpnDate>
</CorporateBondSec>'
I see you have a few extra '\' characters before double quotes. you need to remove them.
