How to increase in mail message font size in asp.net

To increase the font size of a mail message in ASP.NET, you can use the Font property of the MailMessage class. Here are a few ways to do it:

Method 1: Using the Font property

You can set the font size using the Font property of the MailMessage class. Here's an example:

MailMessage mail = new MailMessage();
mail.Body = "This is a test message";
mail.Font = new Font("Arial", 12); // Set font size to 12 points

Method 2: Using the AlternateViews collection

You can also use the AlternateViews collection to specify a different font size for the mail message. Here's an example:

MailMessage mail = new MailMessage();
mail.Body = "This is a test message";
AlternateView av = AlternateView.CreateAlternateViewFromString(mail.Body, null, "text/html");
av.ContentType.Add("font-size", "12pt"); // Set font size to 12 points
mail.AlternateViews.Add(av);

Method 3: Using a template

You can also use a template to specify the font size for the mail message. Here's an example:

MailMessage mail = new MailMessage();
mail.Body = "This is a test message";
string body = string.Format("<font size='12'>{0}</font>", mail.Body);
mail.Body = body;

In this example, we're using an HTML template to specify the font size. The <font size='12'> tag sets the font size to 12 points.

Note: The font size specified in the MailMessage object will override any font settings specified in the email client or server.
