I think this has nothing to do with validation. Its rather masking/prefilling a textbox.
The easy way could be two textboxes between the labels "@" and ".com".

=> [ ]@[ ].com

You don't really need a masked text box. You should just put this code where you want to validate the email.

C#

if (TextBox1.Text.Contains("@")) {
    if (TextBox1.Text.Contains(".com")) {
        MessageBox.Show("Valid Email");
    }
} else {

}

Text.ToString.Contains?? That is not c# code!!
Text is already a String value
Contains is not a property of text.,...bad solution! --> Sorry my bad!

contains is a property of .ToString do your research man.

It is? Since when? According to MSDN Contains is a method (not a property) of the String class.
Your code will not compile.
Calling ToString on a string is useless
MsgBox is undefined

Hi,

You can use a regular expression:

Instead of a RegEx to validate an email address, you can also try this:

[EDIT]

Just checking whether the given email address contains "@" and ".com" wouldn't be enough to validate an email address: if you just would check for "@" and ".com", then even .com@ would be valid.
