c# - Search rasphone pbk file -

in application i'm using rasphone function connect vpn's when application launches gets vpn connections in combobox using code.

string f = environment.getfolderpath(environment.specialfolder.applicationdata) + @"\microsoft\network\connections\pbk\rasphone.pbk";          if (system.io.file.exists(f))         {             list<string> lines = new list<string>();              using (streamreader r = new streamreader(f))             {                 string line;                 while ((line = r.readline()) != null)                 {                      lines.add(line);                 }             }              foreach (string s in lines)             {                 if (s.startswith("["))                 {                     char[] mychar = { ']' };                     string newstring = s.trimend(mychar);                     char[] mychar2 = { '[' };                     string newstring2 = newstring.trimstart(mychar2);                     combobox1.items.add(newstring2);                 }             }         }         else         {             messagebox.show("pbk file not found.");         }         combobox1.sorted = true; 

now question how can phonenumer= section display in textbox or label, know ip is.

a pbk file looks (had delete rows), problem have multiple vpn connections in pbk file multiple phonenumer= entries.

[vpn name of connection] encoding=1 pbversion=3 type=2   device=vpn phonenumber= 0.0.0.0 <- ip address want display in label or textbox. areacode= countrycode=0 countryid=0 usedialingrules=0 comment= friendlyname= lastselectedphone=0 promotealternates=0 trynextalternateonfail=1 

if looking simple solution , understand question correctly should trick, add following statement after current if in foreach statement

else if(str.contains("phonenumber")) {     var x = str.split('=');     if(x.length > 1)     ip = x[1]; } 

please note ip variable store ip-address.

to answer question in comments , assuming have [vpn-connection] before each phonenumber entry write this

        foreach (string s in lines)         {             if (s.startswith("["))             {                 char[] mychar = { ']' };                 string newstring = s.trimend(mychar);                 char[] mychar2 = { '[' };                 string newstring2 = newstring.trimstart(mychar2);                 combobox1.items.add(newstring2);             }             else if (s.contains("phonenumber"))             {                 string ip = combobox1.items[combobox1.items.count - 1].tostring() + " : ";                 var x = s.split('=');                 if (x.length > 1)                     ip += x[1];             }         } 

this item last added combobox , put before string of ip address, still simple hack 1 way it.. if have more advanced needs make class store data require , populate combobox that.
