Problem with sending mail

Hi
I'm struggling with sending mail with c#.
This is the code I found on the web.
I don't have a server so I think I can't use something in this code.
I'm not familiar with the mail syntax smtp etc.

I figured I could do this the easy way.
Create a webmail account such as gmail, give the password and username and use this.
But this code doesn't work like this.
If you know a working snippet then please refer me to it.

public void SendMail(){


MailMessage mail = new MailMessage();


mail.To.Add([email protected]);


mail.From = new MailAddress([email protected]);


mail.Subject = "Test";
 

string Body = "Lorem ipsum dolor sit amet,...

";
mail.Body = Body;

SmtpClient smtp = new SmtpClient("smtp.gmail.com");


	try{


	smtp.Send(mail);


	catch (Exception ex){


	MessageBox.Show(ex.ToString());

Thank You
