I have an LDAP Query I need to build the domain.
So, split by "DC=" up to a "comma"
INPUT:
LDAP://DC=SOMETHINGS,DC=ELSE,DC=NET\\account
RESULT:
SOMETHING.ELSE.NET
You can do it pretty simple using DC=(\\w*)
regex pattern.
var str = @"LDAP://DC=SOMETHINGS,DC=ELSE,DC=NET\account";
var result = String.Join(".", Regex.Matches(str, @"DC=(\w*)")
.Cast<Match>()
.Select(m => m.Groups[1].Value));
Without Regex you can do:
string ldapStr = @"LDAP://DC=SOMETHINGS,DC=ELSE,DC=NET\account";
int startIndex = ldapStr.IndexOf("DC=");
int length = ldapStr.LastIndexOf("DC=") - startIndex;
string output = null;
if (startIndex >= 0 && length <= ldapStr.Length)
{
string domainComponentStr = ldapStr.Substring(startIndex, length);
output = String.Join(".",domainComponentStr.Split(new[] {"DC=", ","}, StringSplitOptions.RemoveEmptyEntries));
}
If you are always going to get the string in similar format than you can also do:
string ldapStr = @"LDAP://DC=SOMETHINGS,DC=ELSE,DC=NET\account";
var outputStr = String.Join(".", ldapStr.Split(new[] {"DC=", ",","\\"}, StringSplitOptions.RemoveEmptyEntries)
.Skip(1)
.Take(3));
And you will get:
outputStr = "SOMETHINGS.ELSE.NET"
