If there are a number of varying cases like that, maybe a regular expression would be better.

So you need to check whether the email address ends with "abc.com" or not, don't you?

Need this function:
private bool checkForSubDomain(string emailAddr)
{
return (emailAddr.IndexOf('.', emailAddr.IndexOf('.'), 2) == emailAddr.LastIndexOf('.'));
}
Then you could do something like this if you need JUST the domain (without the TLD):
char [] findChar = (checkForSubDomain(emailAddr))?new char[] {'.'}:new char[] {'@'};
string emailDomain = emailAddr.Substring(emailAddr.IndexOf(findChar)+1, (emailAddr.Length - (emailAddr.IndexOf(findChar)+1)) - (emailAddr.Length - emailAddr.LastIndexOf('.')));
This is quick and sloppy but, I'm sure you could make it better 
[EDITS]
Never mind this crap it wouldn't work with .co.uk and ect..

I guess you're trying to validate whether an email domain exists or not?
There's no real way to do this other than querying DNS for MX records to determine who handles mail for this domain. No regular expression will work. See section 5 of RFC 2821[^] for details.

Actually mike is right...
What I posted won't work for .co.uk (DOH! American idealist shows in me again) so blah@somthing.co.uk would return "co" as the domain... There are infinite things like this :/ yea not possible (It' not a good thinking morning for me today)

Plz tell me how do I force the printer to print in grayscale mode from C#?
(Here I don't want the user to see the print setup dialog box)
Have a nice day

For printing using C# code, you could read this[^].
Set the PageSettings.Color property to false to disable the color printing. The printout will be converted to grayscale.

Hello everyone,
I did some research for File.Create API to find some option which could be used to create a new file, with exclusive owner mode (e.g. other process/thread can not delete/open/modify when current thread keep the file open). But can not find it out.
Could anyone let me know which option should I use or which API should I use?
thanks in advance,
George

If you create it using a FileStream then you can specify whether you get exclusive rights to it in the constructor. As long as you don't close the handle then other processes can't modify it.

Thanks Ed.Poore,
I have found it out. I think I need to FileStream.Close(), or else other thread/process can not use it?
regards,
George

As long as the process holds sway on the file, other processes would be denied any access to it.

Thanks Vasudevan,
If a process holds a file handle in exclusive mode, and the process terminates without close the handle. Will kernel release the handle automatically, so that other process can access?

Hi,
We have a web service in .NET framework version 2.0 (C#). We need to create a function
in that web service with name ilke, say, 'ABC'.
We want this function to be displayed as "A B C" - in other words, its display name
should contain spaces.
In .NET framework 1.1, we are able to do this, by using the message_name attribute of
the web method. We gave the function name, with spaces, in the message_name attribute
and it displayed alright. When we give it in message_name attribute of web method in
version 2.0, it is displaying the function name itself.
Is there a way where we can display a function name in a web service WITH spaces, in
.NET framework version 2.0.
Thansk in advance

string spaceName = string.Join(" ", (function.Name.Split(new char{''}))); maybe??
I make no promise that the code above follow "good" code design, furthmore that the code above even works; due to me just spitting it out. If you do want to use something like this it would be better to used a StringBuilder
