That's exactly what you put in the array, you are only adding the values wrong.
256 * 1 + 44 = 300

Uhmmm, do you call yourself a developer? With all due respect, I suppose you are working for one of the Indian companies that is robbing Americans of jobs. Figure it out yourself and then ask questions if you run into problems. That is what REAL developers do.

I have the following string "\1 tag1 \2 tag2 \3 tag3", how do I declare this one in C#?
(the \1 \2 \3 are special characters)

Try
string st = "\\1 tag1 \\2 tag2 \\3 tag3";
or
string st = @"\1 tag1 \2 tag2 \3 tag3";
Best regards, Alexey.

Thanks, but this is local authentication. If use this way, at server you can receive more information for client user, but you will not know this information, that sent from valid user or not

You said all your machines are in an Active Directory domain. The WindowsIdentity is not local to the machine when in a domain environment. Unless, of course, the user picked the local machine as the domain name when he/she logged in.

Example:
User A and user B in domain, they is authenticated. User A run a app client, if he send information about A then no problem, but he use infomation of B to send to server. B is authenticated, so server accept request.
I want server only accept when A send information of A? Do you think?

Now you've got a problem that ha snothing to do with Windows Authentication. This is a data security problem specific your data model. If anyone can impersonate anyone else simply by typing information into a TextBox, you have to implement something to prevent this. But, what and how you do this is entirely dependant on your data model and requirements.
Have you looked at the properties of the WindowsIdentity class?
