There can be multiple methods, static void Main(string[] args) { List AuthorList = new List (); // Add items using Add method AuthorList.Add( "Name :Mahesh Chand,Adress:Hyd" ); AuthorList.Add( "Name:Praveen Kumar,Adress:Pune" ); AuthorList.Add( " " ); AuthorList.Add( "Name:Nipun Tomar,Adress:Delhi" ); AuthorList.Add( "Name:Dinesh Beniwal" ); Console.WriteLine( "Names: " ); foreach(var item in SplitNameAndAddress(AuthorList)[0]) { Console.WriteLine(item); } Console.WriteLine( "Address: " ); foreach (var item in SplitNameAndAddress(AuthorList)[1]) { Console.WriteLine(item); } Console.ReadLine(); } public static List > SplitNameAndAddress(List list) { var obj = new List >(); List Names = new List (); List Addresses = new List (); foreach (var item in list) { if (!(string.IsNullOrEmpty(item) || string.IsNullOrWhiteSpace(item))) { if (item.Contains( "," )) { var Name = (item.Split( "," )[0]).Split( ":" )[1]; var Address = item.Split( "," )[1].Split( ":" )[1]; Names.Add(Name); Addresses.Add(Address); } else { Names.Add(item.Split( ":" )[1]); } } } obj.Add(Names); obj.Add(Addresses); return obj; }

I wanted to come up with a real object-oriented solution starting with a class that uses factory method pattern to parse a string of necessary input public class Author { public string Name { get ; set ; } public string Address { get ; set ; } private Author( string name, string address) { Name = name; Address = address; } public static Author Create( string input) { var (prefixedName, prefixedAddress) = ExtractPrefixedNameAndAddress(input); var name = RemovePrefix(prefixedName); var address = RemovePrefix(prefixedAddress); return new Author(name, address); } public static Author TryCreate( string input) { try { return Create(input); } catch (ArgumentException) { return null ; } } private static ( string , string ) ExtractPrefixedNameAndAddress( string input) { var splitted = input.Split( ',' ); if (splitted.Length != 2) { throw new ArgumentException( "Input has incorrect format" ); } return (splitted[0], splitted[1]); } private static string RemovePrefix( string prefixedItem) { var splitted = prefixedItem.Split( ':' ); if (splitted.Length != 2) { throw new ArgumentException( "Input has incorrect format" ); } return splitted[1]; } } After the class is constructed the task is plain simple: filter out clearly invalid inputs, try construct items of the class, filter out those that failed to create and print necessary stuff. Here's the code var authors = AuthorList .Where(p => ! string .IsNullOrWhiteSpace(p)) .Select(p => Author.TryCreate(p)) .Where(p => p != null ) .ToList(); //avoid multiple enumerations foreach (var author in authors) { Console.WriteLine(author.Name); } foreach (var author in authors) { Console.WriteLine(author.Address); } result is Mahesh Chand Praveen Kumar Nipun Tomar Hyd Pune Delhi

You can do in this way. //AuthorName Console.WriteLine( "Output Author Name" ); foreach ( string author in AuthorsList) { var authorName = author.Split( ":" )[1]; Console.WriteLine(authorName); } //AuthorCity Console.WriteLine( "Output Author City" ); foreach ( string author in AuthorsList) { var authorCity = author.Split( ":" )[2]; Console.WriteLine(authorCity); }

Try this List string > AuthorList = new List string >(); // Add items using Add method AuthorList.Add( "Name :Mahesh Chand,Adress:Hyd" ); AuthorList.Add( "Name:Praveen Kumar,Adress:Pune" ); AuthorList.Add( " " ); AuthorList.Add( "Name:Nipun Tomar,Adress:Delhi" ); AuthorList.Add( "Name:Dinesh Beniwal" ); //AuthorName Console.WriteLine( "Output Author Name" ); foreach ( string author in AuthorsList) { var authorName = author.Split( ":" )[1]; Console.WriteLine(authorName); } //AuthorCity Console.WriteLine( "Output Author City" ); foreach ( string author in AuthorsList) { var authorCity = author.Split( ":" )[2]; Console.WriteLine(authorCity); }

Anu Viswan · Answer

Since most of the earlier answers are based on string.split, here is another approach using the Regular expressions . var nameList = new List string >(); var addressList = new List string >(); var regex = new Regex(@ "^Name\s*:(? [^,]*\s*),\s*Adress\s*:(? \w*\s*)$" ); foreach (var author in AuthorList) { var match = regex.Match(author); if (match.Success) { nameList.Add(match.Groups[ "NameValue" ].Value); addressList.Add(match.Groups[ "AddressValue" ].Value); } } foreach (var author in nameList) Console.WriteLine(author); foreach (var address in addressList) Console.WriteLine(address);

Hi, Try below code. Console.WriteLine( "Author Name" ); foreach (var author in AuthorsList) { var name = author.Split( ":" )[1]; Console.WriteLine(name); } Console.WriteLine( "Author City" ); foreach (var author in AuthorsList) { var city = author.Split( ":" )[2]; Console.WriteLine(city); }

forech(var item in AuthorList) { string[] AutherandAddress= s.Split( ':' ); Console.WriteLine( "Author Name: {o} and Author Address: {1}" ,AutherandAddress[0],AutherandAddress[1] ) }

public class Program { public static void Main() { List AuthorList = new List (); // Add items using Add method AuthorList.Add("Name :Mahesh Chand,Adress:Hyd"); AuthorList.Add("Name:Praveen Kumar,Adress:Pune"); AuthorList.Add("Name:Nipun Tomar,Adress:Delhi"); //AuthorName Console.WriteLine("Output Author Name and Adress"); foreach (string author in AuthorList) { var authorName = author.Split(Convert.ToChar(":"))[1]; var authorCity = author.Split(Convert.ToChar(":"))[2]; Console.WriteLine(authorName); Console.WriteLine(authorCity); } } } Ouput; Output Author Name and Adress Mahesh Chand,Adress Hyd Praveen Kumar,Adress Pune Nipun Tomar,Adress Delhi Still not solved my quetion
