Email formatting in code behind

I need to send an email to a customer that has just completed a transaction but I am having some difficulties in drafting out the format in code behind, this is my code, apparently it's appearing as one straight line of text in the body of my mail, how can I format it in such a way it appears something like, any help is appreciated, thanks :

This is my code:

                mail.To.Add(u.Email);
                mail.From = new MailAddress("me@hotmail.com");
                mail.Subject = "Purchase invoice" + newOrder.OrderID;

                string bodyText = "";
                double unitQtyPrice = 0;
                double totalPrice = 0;
                foreach (var cItem in cartList)
                {
                    Math.Round(cItem.UnitCost, 2);

                    bodyText = bodyText + '\n' 
                               + cItem.ProductID.ToString() + '\t'
                               + cItem.ModelName + '\t'

            开发者_开发知识库         unitQtyPrice = cItem.Quantity * (double)cItem.UnitCost;
                     totalPrice += unitQtyPrice;          
                }

                    throw new Exception("ERROR: Fail to send email - " + exp.Message.ToString(), exp);
                }

You have it set to HTML, which is whitespace-insensitive. If you want it to be sent as plaintext with line breaks and all, don't set IsBodyHtml.

Alternatively, you can include actual HTML markup to lay out your email, which may be a better solution.

Just write you mail.Body part in an HTML language...

and set

mail.IsBodyHtml = true;
