String Replace and Search Filter

Hi i wrote a class file

in my class file am trying to achieve like this

but am getting this error :String cannot be of zero length.

if (username.Contains("."))
{
string Fname = username.Substring(0, username.IndexOf("."));
Fname = Fname.Replace("", " ");
string[] splitString = username.Split(new char[] { '.' });
username = splitString[splitString.Length - 1];

}

if (username.IndexOf(" ") > 0)
search.Filter = "(cn=" + username + ")";
else
search.Filter = "(sn=" + username + ")" & "(givenname=" + Fname + "));

in this case,if i pass a string like Joe will.smith

then

My first name should be : Joewill (it should eliminate the space,if space is there,if not leave it as it is)
lastname=smith

then i will use the search filter against "sn" and "givenname" retrieve the user info.

Please correct my mistakes,its throwing an error.

string[] names;
if (username.Contains("."))
{
names = username.Split(new char[] {'.'},StringSplitOptions.RemoveEmptyEntries);
names[0] = names[0].Replace(" ", "");
}

//Now names[0] is first name and names[1] is last name

Hi Mamtha,

Thanks for your response,how can i pass first name and last name in to my search filter

something like this

search.Filter = "(sn=" + username + ")" & "(givenname=" + Fname + "));

Hi,
Try this code:

string first, last;
string data = "Joe will.smith";

string newdata = data.Replace(" ", ""); // Remove spaces.

char[] sep = {'.'};
string[] words = newdata.Split(sep, StringSplitOptions.RemoveEmptyEntries);

if (words.Length != 2)
{
// Error.
}
else
{
first = words[0];
last = words[1];
}

Something like this(not sure about your Filter syntax):

string[] names;
if (username.Contains("."))
{
names = username.Split(new char[] {'.'},StringSplitOptions.RemoveEmptyEntries);
names[0] = names[0].Replace(" ", "");
}

//Now names[0] is first name and names[1] is last name
search.Filter = "(sn=" + names[0] + ")" + " (givenname=" + names[1] + ")";

thanks Mamtha,

your replace condition works perfectly,but when i pass name[0] and names[1] in my search filter it throws error like

search.Filter = "(sn=" + names[0] + ")(givenname=" + names[1] + ")";

Error: use of unassigned local variable "names".

am not sure why its not recoganized

Here is the modified code but still i can't pass the Fname to my search filter its thowing error :

"The name (fname) doesn't exist in the current context"

 if (username.Contains("."))
            {
                string Fname = username.Substring(0, username.IndexOf("."));
                Fname = Fname.Replace(" ", "");

                string[] splitString = username.Split(new char[] { '.' });
                username = splitString[splitString.Length - 1];

}


if (username.IndexOf(" ") > 0)

                    search.Filter = "(cn=" + username + ")";

                else

                      search.Filter = "(sn=" + username + ")(givenname=" + Fname + ")";
