how to store ,retrieve xml file into database by using webservices in .net?

Question

This question is not clear so I will write a general answer. I assume, you have a column in your database that stores the contents of XML files. You need to create a Web Service using Visual Studio 2005 (or whatever version you are using). This Web service should have two methods. Let's call them - GetXmlFileData and SaveXmlFile. In GetXmlFileData method, you will open a connection with your database using ADO.NET and get the value of the table and column(s) from the database. This method can return a DataSet itself that can have all rows from the table or selected rows depending on your query. The contents of a DataSet can be read into an XML fragment and you can easily convert them to a XmlReader and save as XML file. See my references below on how to do it. Now, in your SaveXmlFile method, you will read an XML document using the reader and pass the content of it in method as an XmlDocument or XmlNode or text. Whatever you like. Then your SaveXmlFile method will call ADO.NET database stored procedure or query, depending on your implementation and will save in the database. I hope this gives you some pointers and direction.
