Serializing Lists of Classes to XML

So some times we want to convert object to xml. We can follow severel cumbersome methods. So I am using Utlity methods to convert c# object to xml and xml to c# object. Suppose we have class like below And we want serialize List<Student> to xml. So we can use this utlity function As a example we populate List<student> ¬†with dummy data Then call out utility function then out xml variable look like as below  

The remote server returned an error: (417) Expectation failed is solved

So finally I salved this error by applying following things. Adding following statement right before calling web method ¬†System.Net.ServicePointManager.Expect100Continue = false. 2. Adding following section in web.config inside <configuration> <settings> <servicePointManager expect100Continue=”false” /> </settings> more detail on MSDN
