Man, i got scared when i looked at the time i need to wait for this to complete. All i wanted to do is to copy a file on a Wireless (n) Network for 388MB. Somebody at Microsoft need to go back to Elementary School to fix the Math confusion.

I was curiout about this tool in Microsoft which can generate classes to serialize/deserialize XSD based xml files back and forth. I installed the tool provided  by microsoft in my previous column. Created a small project with customers/customer xml snippet and tested it. It was simple and worked great.

To read existing xml generated for xsd:

private void ReadExistingFile(ref FileStream fStream, ref MemoryStream mStream)
 {
 fStream = new FileStream(”XMLFile1.xml”, FileMode.Open);

 byte[] byteArray = new byte[90000];
 mStream = new MemoryStream(byteArray);

 // root xsd class
 XmlSerializer s = new XmlSerializer(typeof(customers));
 customers allcustomers = (customers)s.Deserialize(fStream);

 foreach (customer c in allcustomers)
 {
 textBox1.Text += c.id + “\r\n”;
 }
 }

Also to create a new snippet:

private static FileStream WriteANewXMLForThisXSDGeneratedClass(FileStream fStream2)
 {
 // write something new
 fStream2 = new FileStream(”XMLFile2.xml”, FileMode.Create);
 customers tobeWritten = new customers();
 customer muthu = new customer();
 muthu.id = “one”;
 muthu.name = “muthu”;

 customer kumar = new customer();
 kumar.id = “two”;
 kumar.name = “kumar”;

 tobeWritten.Add(muthu);
 tobeWritten.Add(kumar);

 XmlSerializer s = new XmlSerializer(typeof(customers));
 s.Serialize(fStream2, tobeWritten);
 return fStream2;
 }

It’s really cool…..

• Download the entire solution from here: Sample

Sometimes, you might have found some schema files which you wanted to manipulate in your code with .NET. Microsoft provides a sample XSD to C#/VB.NET converter as a download to do this task yourself. Please at the following details to download it and use it.

Overview

The Sample Code Generator (XSDObjectGen) tool takes an XSD schema as input and generates sample code showing how to mark up C# and VB.Net classes so that when serialized with the XML serializer, the resulting XML will be valid according to the original schema. This update fixes some documentation changes and corrects a problem where the wizard did not generate code in some environments.
