What does _Default keyword mean in c#

Question

For example, I have created a webpage and it has _Default keyword in it.

public partial class _Default : System.Web.UI.Page 

What does that keyword do in here? What is the point ?

Answer 1

_Default isn't a keyword, it's your class name.

Answer 2

It is not a keyword, that is the name of the class. Variable names can start with a-z, A-Z, and '_'.

Answer 3

default is a keyword used in the C# switch statement, and in VB.Net applies to a default property. That's why the IDE renamed your class _Default, based on the name of the page (Default.aspx). _Default is in itself not a keyword, and appears to be colored differently because every other word on that line is a keyword.

Answer 4

keyword names are lowercase. this is your class name. if your page name is default, asp.net get this name to it's class.
