I want to create a Regular Input Mask Validation for any email address that has .COM to it. But I don't want to allow anything with .NET

For example

Amy's email isamy@hello.com
Bill's email isbill@yes.net
Tim's email istim@nope.com

Now I will only allow Amy and Tim's email address to be entered. So this is what I came up with.

Regex mask = new Regex(@"^[\w\.-]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]\.com+$",  
RegexOptions.IgnoreCase|RegexOptions.Multiline);

Also, what if I wanted to allow both .COM and .NET to be entered?
Regex mask = new Regex(@"^[\w\.-]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]\.com+  
|^[\w\.-]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]\.com+|^[\w\.-]{1,}\  
@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]\.com+|^[\w\.-]{1,}\  
@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]  
\.net+$",RegexOptions.IgnoreCase|RegexOptions.Multiline);

or maybe

Regex mask = new Regex(@"^[\w\.-]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]\  
.com|net+$",RegexOptions.IgnoreCase|RegexOptions.Multiline);
