Replace the Field in a txt File

Friends,
New to Asp.net programming. Begging your patience here.

Im  trying to parse a txt file . The text file  is a comma delimited file and the fields are enclosed in quotes.
The file has rows of data like this.

"CareType" ,"Company" ,"CareNumber", "HomeCare","ABCComapny","WC3456","lastName","Hollman"

The "keys" will always remain the same, throughout the file, only values change,And the keys are fixed in position.

Im trying to eliminate the "keys" and just retain the values like:
 "HomeCare","WC3456","Hollman"

Im using TextFieldParser to read through the fields.
I want to loop through the FieldRows and simply delete the "Key" fields and save the .txt file.

Right now i'm having this code:

using (TextFieldParser parser = new TextFieldParser(filename.FullName))
                              {
                               
                                   parser.Delimiters = new string[] { "," };
                                parser.HasFieldsEnclosedInQuotes = true;
                               
                               while (!parser.EndOfData)
                                  {
                                        string[] FieldRow = parser.ReadFields();
                             
                                                          //int Rowlength=FieldRow.Length;
                               
                                                        if (FieldRow[0]=="CareType")
                                                         {
                                       
                                                             // I want to Replace the key with null or simply delete here.
                                                            //save the .txt file here.
                                                               I cant use FieldRow[0].Replace("careType","");


                                                        }
                                 
                                         
                                     }
                              }

You probably want to use Except() on the array; e.g. -
using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualBasic.FileIO;

namespace EE_Q28907159
{
	class Program
	{
		static void Main(string[] args)
		{
			List<string> results = new List<string>();
			using (TextFieldParser parser = new TextFieldParser("EE_Q28907159.txt") { Delimiters = new[] { "," }, HasFieldsEnclosedInQuotes = true })
			{
				while (!parser.EndOfData)
				{
					string[] row = parser.ReadFields();
					results.Add(string.Join(",", row.Except(new[] {"caretype", "company", "carenumber", "abccomapny", "lastname"}, StringComparer.OrdinalIgnoreCase).ToArray()));
				}
			}

			foreach (var result in results)
				Console.WriteLine(result);
			Console.ReadLine();
		}
	}
}

Which produces the following output -Capture.JPGYou just want to place the *key* fields into the new array that is passed to the Except method; e.g. -
FieldRow = FieldRow.Except(new[] {"caretype", "company", "carenumber", "abccomapny", "lastname"}, StringComparer.OrdinalIgnoreCase).ToArray();
