How to use return value of javacript alert function when we use in C# by RegisterStartupScript.

This is my code:
string scriptString = "<script language='javascript'>" +
"confirm("are u sure to book this?");</script>";

You could change the script a little, like:

string scriptString = "<script language='javascript'>" +
"return confirm("are u sure to book this?");</script>";

If you are wanting to execute code in a button event when the user clicks ok, or do nothing when they click cancel - try this - put it in the page_load routine:

btnButtonName.Attributes.Add("onclick", "return confirm('are u sure to book this?')");

Have fun :D
