Hi,

An exception of type 'System.Xml.XmlException' occurred in System.Xml.dll but was not handled in user code

Using code:

HttpWebRequest request = CreateSOAPWebRequest();

XmlDocument SOAPReqBody = new XmlDocument();

//SOAP Body Request

StringBuilder strRequest = new StringBuilder();

strRequest.Append("");

strRequest.Append("");

strRequest.Append("");

strRequest.Append("");

strRequest.Append("");

strRequest.Append("" + constant.Roomkey + "

strRequest.Append("");

strRequest.Append("");

strRequest.Append("");

SOAPReqBody.LoadXml(strRequest.ToString());

Please help me to solve this error.

Accepted answer
did you place a debug point on the line strRequest.ToString() and see what's inside the string?

it's not a well formed xml that's why the error.

if you simply copy the string content into any xml file in VS or any other xml editor it will immediately tell you what's wrong with the xml.
you are not closing properly, the below line missing ">" - strRequest.Append("" + constant.Roomkey + "
your start tag is and end tag is
soap:Envelope>
It should be same i.e.
that's it!
