XML Serialization in .Net



Namespace: System.XML.Serialization

It provides Greater interoperability, More Administrative friendly, better forward-compatibility.

Using XML Serialization:

FileStream fs = new FileStream(“FileStream.xml”, FileMode.Create);
XmlSerializer xs = new XmlSerializer(typeof(DateTime)); //Optional to specify

xs.Serilize(fs,System.DateTime.Now);

Fs.close();

Deserializing objects:

FileStream fs = new FileStream(“FileStream.xml”, FileMode.Open);
XmlSerializer xs = new XmlSerializer(typeof(DateTime)); //Optional to specify
Console.WriteLine(“Previouse Date : ” + (DateTime)xs.Deserialize(fs));
Fs.close();


Rules for XML Serialization:
• Specify the class as public
• A public parameter less Constructor
• Members to be serialized must be public.

XML Serialization can be controlled using XmlAnyAttribute, XmlAnyElement, XmlArray, XmlArrayItem, XmlAttribute, XmlChoiceIdentifier, XmlElement, XmlEnum, XmlIgnore, XmlInclude, XmlRoot, XmlText, and XmlType.

How to conform XML to an XML Schema?
If you have a schema file, use XSD.exe and it generates all classes crossponding to that in schema. And when those classes are serialized the generated Xml will be according to the schema.
Command line to generate classes:

Xsd.exe MyXsdSchema.xsd /classes /language:cs

Culture Information and Localization in .NET

Namespace: System.Globalization CultureInfo Class:                 It provides information like the Format of numbers and dates, Culture’s Calendar, Culture’s language and sublanguage (if applicable), Country and region of the culture. The Basic use of CultureInfo class is shown here: • How string Comparisons are performed • How Number Comparison & Formats are performed • Date Comparison and Formats. • How resources are retrieved and used. Cultures are grouped into three categories: Invariant Culture : It’s Culture Insensitive. It can be used to build some trial application. It can be also used to build an application with hard-coded expiry date that ignores cultures. But using it for every comparison will be incorrect and inappropriate. Neutral Culture : English(en), Frensh(fr), and Spanish(sp). A neutral culture is related to language but it’s not related to specific regi...

Concept of App Domain in .Net

Creating Application Domains: Application domain is just like process, provides separate memory space, and isolates from other code. But it’s quite light weight. It also provides the following advantages: 1-       Reliability : If a domain crashes, it can be unloaded. Hence doesn’t affect the other assemblies. 2-       Efficiency : Loading all assemblies in one domain can be cumbersome and can make the process heavy but Appdomains are efficient in this manner. Important properties of AppDomain: ApplicationIdentity , ApplicationTrust , BaseDirectory , CurrentDomain , DomainManager , DomainDirectory , Evidence , FriendlyName , ID , RelativeSearchPath , SetupInformation , ShadowCopyFiles . Important methods of AppDomain: ApplyPolicy , CreateCOMInstanceFrom , CreateDomain , CreateInstance (Assembly). To create an AppDomain: AppDomain adomain = AppDomain.CreateDomain(“D”); To execute an assembly:...

Asynchronous Execution in ASP.NET

Asynchronous Execution: Two ways either implement IHTTPAsyncHandler interface or in ASP.NET 2.0 set <%@ Page Async=”true” %>. The second option implements IHTTPAsyncHandler interface automatically for the page when parsed or compiled. AddOnPreRenderCompleteAsync ( new BeginEventHandler(BeginTask), new EndEventHandler(EndTask)); AddOnPreRenderCompleteAsync() shoud be called in Page_load. The BeginEventHandler and EndEventHandler are delegates defined as follows: IAsyncResult BeginEventHandler( object sender, EventArgs e, AsyncCallback cb, object state) void EndEventHandler( IAsyncResult ar) AsyncProcess starts and completes between PreRender and PreRenderComplete. Other way to perform Async Task is using AsyncPageTask structure. It also allows multiple tasks to execute simultaneously. void Page_Load (object sender, EventArgs e) { PageAsyncTask task = new PageAsyncTask( new BeginEventHandler(BeginTask), new EndEventH...
