what is the difference between writing a code within #region and endregion and wrtiing it normally.

why in some programs they write code in between #region and Endregion.

When pasting as a region, the clipboard text will simply appear between #region and #endregion tags with a region name of your choice. This feature is often helpful when organizing code within your application or pasting regions of code developed by someone else.

First, copy a piece of code like this one to your clipboard:

private void DoSomething( )
{
//Write Code Here
}

Then select Paste As -> Region, and you will see the dialog shown in Figure 2-5.

From this dialog, you specify the name of the region that you want to use; after you click OK, this code will be pasted into your document:

#region DoSomething Method
private void DoSomething( )
{
//Write Code Here
}
#endregion

the Page.Control at the given index, the Page.Controls.Count decreases by
one.
