    Dear Mazen thanks for your comment , hope my post helps you
    about the Error you got
    – Error 1 :-
    the name Text_Email does not exist in the current context
    You should add TextBox with ID =”txt_Email” which will contain the email of user which will send Email to you or to anyone.

    – Error 2 :-
    the name Text_Message does not exist in the current context
    This mean you should add TextBox control with ID= “txt_Message” which will contain message or body of Email

    – Error 3 :-
    expexted catch or finally ( at default.aspx.cs line: 66)
    This mean you should use Catch to handle any Exception that can happen

    Hope this helps
    if you have any question send me
    Good Luck
