Finding and removing items from a text file?

Hey guys, I've built a program that adding info to a text file. Its user database for a record collection, it can add band's info to a text file, but I want to let the user search for and remove band's info if the user sells the band's record. Not sure how to go about this. I'm watching the C# course videos, but thought I could get some other input about other ways of going about it.
here is my current code:

Thanks :)

    Hi @Scott George ,
    In order to correctly save the data into your text file, you need to change

                ("{0}", ".", "{1}", ".", "{2}", ".", "{3}", ".", "{4}", ".",  
                 "{5}", ".", "{6}", ".") + Environment.NewLine);  


     File.AppendAllText(@"test.txt",$"{artist}.{formationDate}.{favoriteAlbum}.{yearOfRelease}.{numberOfSongs}.{genre}" + Environment.NewLine);  

    Then, you can refer to the following code to removing the certain line from a text file.

            public static void removeArtist()  
                Console.Write("Please enter the artist name you want to delete: ");  
                string name = Console.ReadLine();  
                List<string> lst = File.ReadAllLines("Data.txt").Where(arg => !string.IsNullOrWhiteSpace(arg)).ToList();  
                lst.RemoveAll(x => x.Split('.')[0].Equals(name));  
                File.WriteAllLines("Data.txt", lst);  

    Hope it could be helpful.
