ASP.Net Coding Standards

Naming and Capitalisation

Identifier	Case	Examples	Additional Notes	Detailed Info
Class	Pascal	Person, BankVault, SMSMessage, Dept	Class names should be based on "objects" or "real things" and should generally be nouns.
Method	Pascal	GetDetails, UpdateStore	Methods should use verbsor verb phrases.
Parameter	camel	personName, bankCode
Interface	Pascal with "I" prefix	IDisposable	One of the few times when prefixing is adopted.
Property Associated private member variable	Pascal _camelCase	ForeColor, BackColor _foreColor, _backColor	Use underscore camel casing for the private member variables, but keep the names the same as associated property accessors.
Exception Class	Pascal with "Exception" suffix	WebException, SMSException
Event	Pascal plus optional "EventHandler" suffix where relevant	btnSubmit_Click, Painting, Click, Clicked, MyEventHandler	VS uses underscores to separate an object from its event. Be careful with tense (pre/past), e.g. a Close event that can be canceled should have a Closing event and a Closed event. MS also recommend adding the "EventHandler" suffix where thought needed.
