Remove domain information from login id in C#
提问by Dan
I would like to remove the domain/computer information from a login id in C#. So, I would like to make either "Domain\me" or "Domain\me" just "me". I could always check for the existence of either, and use that as the index to start the substring...but I am looking for something more elegant and compact.
我想从 C# 中的登录 ID 中删除域/计算机信息。所以，我想让“域\我”或“域\我”只是“我”。我总是可以检查两者是否存在，并将其用作索引来启动子字符串......但我正在寻找更优雅和紧凑的东西。
Worse case scenario:
更坏的情况：
int startIndex = 0;
int indexOfSlashesSingle = ResourceLoginName.IndexOf("\");
int indexOfSlashesDouble = ResourceLoginName.IndexOf("\");
if (indexOfSlashesSingle != -1)
startIndex = indexOfSlashesSingle;
else
startIndex = indexOfSlashesDouble;
string shortName = ResourceLoginName.Substring(startIndex, ResourceLoginName.Length-1);

I always do it this way:
我总是这样做：
string[] domainuser;
string Auth_User = Request.ServerVariables["AUTH_USER"].ToString().ToLower();
domainuser = Auth_User.Split('\');
Now you can look at domainuser.Length to see how many parts are there and domainuser[0] for the domain and domainuser[1] for the username.
现在，您可以查看 domainuser.Length 以查看其中有多少部分， domainuser[0] 表示域， domainuser[1] 表示用户名。

string theString = "domain\me";
theString = theString.Split(new char[] { '\' })[theString.Split(new char[] { '\' }).Length - 1];

You could abuse the Path class, thusly:
您可以滥用 Path 类，因此：
string shortName = System.IO.Path.GetFileNameWithoutExtension(ResourceLoginName);

How's about:
怎么样：
string shortName = ResourceLoginName.Split('\')[1]

This works for both valid domain logins:
这适用于两个有效的域登录：
var regex = @"^(.*\)?([^\@]*)(@.*)?$";
var user = Regex.Replace("domain\user", regex, "", RegexOptions.None);
user = Regex.Replace("[email protected]", regex, "", RegexOptions.None);
回答by Derek Smalls
This will work for both but with named groups.
这将适用于两者，但适用于命名组。
^(?<domain>.*)\(?<username>.*)|(?<username>[^\@]*)@(?<domain>.*)?$

小猪支持德里克·斯莫尔斯的回答......
Regex.Replace(User.Identity.Name,@"^(?<domain>.*)\(?<username>.*)|(?<username>[^\@]*)@(?<domain>.*)?$", "${username}", RegexOptions.None)
worked for me.
为我工作。
