Search a string within a string

Question

Hi, I have a search box and want to search a string from a string.i.e, Suppose, str[]= abf,fghi,acb,stabu and if I search for 'ab',then it should display 'abf' and 'stabu' My Code:- List selectedValues = new List (); foreach (string str in completeList) { if(str.Contains(filterWith)) //filterWith is the sequence of characters to be searched selectedValues.Add(str); }

Hi, Agree with Anupam, using the LINQ to object you can find search result. try... string[] str= new [] {"abf","fghi","acb","stabu"}; var k = str.Where(p => p.IndexOf("ab") >= 0).ToList(); hope this will help you.

Hi Sweta, Can you post your complete code: this code looks fine , if you have string array as string[] str= anew [] {"abf","fghi","acb","stabu"}; and want to search "ab" you can get results using string[] results=str.Where(s=>s.Contains("ab")).ToArray();

Anupam Singh · Answer

mention string which you are passing as filterWith

Hi, Can you please share example data? and you want to search only by name right? here you are searching on combination of roll, name and pNo

Thank You.I got my mistake. Actually the list from where I was searching contained upper case letters and i was searching with lower case letters.I did the change.

Hi Anupam, This is my code:- public List getStudentList(string filterWith) { List fullList = new List (); List selectedValues = new List (); String selectQuery = "SELECT name,pNo,roll FROM Student ORDER BY roll DESC"; using (var dbase = new SQLiteConnection(Globals.DB_PATH, true)) { dbase.RunInTransaction(()=> { var listOfNavs = dbase.Query (selectQuery); foreach (ServerVehicles st in listOfNavs) { string str = st.roll + " : " + st.name + " : " + st.pNo; fullList.Add(str); } foreach (string str in fullList) { if(str.Contains(filterWith)) selectedValues.Add(str); } }); dbase.Close(); } return selectedValues; }
