Finding and removing items from a text file?

Question

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

    File.AppendAllText(@"C:\Users\TSG\source\repos\tsgxcode\OMDB\Data.txt",  
            ("{0}", ".", "{1}", ".", "{2}", ".", "{3}", ".", "{4}", ".",  
             "{5}", ".", "{6}", ".") + Environment.NewLine);  

To

 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.
