You can use the below code List string > textn = new List string >( new [] { row[ "PERMISSIONS" ].ToString() }); // row[per] from datatable. string output = string .Join(Environment.NewLine, textn.ToArray()); Console.Write(output); Hope this will help you.

You can use your code similart to the below one with some modification. List string > list = new List string >() { "Red" , "Blue" , "Green" }; string output = string .Join(Environment.NewLine, list.ToArray()); Console.Write(output); The result would be: Red Blue Green Hope this will help you.

Thank you Suraj, Yes, now i can able to read and get expected output(split string). string output = string .Join(Environment.NewLine, textn.ToArray()); woks perfect. but dont know how to clear each loop. i want to cleat during foreach loop. example: 1st row =1,2,3 2nd row =4,5,6 each foreach code lopping previous row data also means output 1st looping row =1,2,3 2nd looping row = 1,2,3,4,5,6 3rd time 1,2,3,4,5,6,7,8 etc. we want only current row value, but it is looping previous row values also. how can clear each loop. foreach (DataRow row in dt.Rows) { char[] mychars = { ';' }; List textn = new List (); textn.Clear(); //clearing here list but no luck textn = new List (new[] { row["Source-USER/GRP PERMISSIONS"].ToString() }); string combindedString = null; //assigning here null eachloop but no luck combindedString = string.Join(Environment.NewLine, textn.ToArray()); string[] names = null; //assigning here null/clearing each loop but no luck names = combindedString.Split(mychars, StringSplitOptions.None); foreach (var item in names) { MessageBox.Show(item.ToString()); } } can you help me here how can i clear each loop, i want to read on current row values.
