Does this demonstrate what you want to do?

 using System;
 using System.Text;

 class App
 {
     static void Main(string[] args)
     {
         string s = "\"hello\",\"world\",\"the\",\"quick\",\"brown\",\"fox\"";

         string[] bits = s.Split(new char[]{'\"', ','});
         Console.WriteLine(s);

         StringBuilder sb = new StringBuilder();
   
         foreach( string b in bits )
         {
             if( b.Length!= 0 )
             {
                 Console.WriteLine(b);
                 sb.Append(b);
             }
         }

         Console.WriteLine(sb.ToString());
     }
 }

 Hello, I have a question in regards to .Net string maniplulation. I have a
 question in regards to interating over individual characters in a string.
 The problem is I have a CSV parser that will successfully parse out quoted
 csv files, the only issue is it will leave the leading and ending quotes in
 tact. Before I go on I do realize since it's a CSV I could do
 stringval.replace( "\"", "" ); but I wanted to take the chance to learn out
 to iterate over string values. Anyway, the problem is what I had written
 originally to do this was:
 
 if ( stringval[0] == '"' ) {
 stringval = stringval.substring( 1, ( stringval.length - 1 ) );
 }
 if( stringval[( stringval.length - 1 )] == '"' ) {
 stringval = stringval.substring( 0, ( stringval.length - 2 ) );
 }
 
 I wasn't stripping off the last " ever and I realize now that the problem
 has to do with .Net storing strings in UNICODE, which allows for character
 pairs to reprisent a single character. So my question here is, how does one
 iterate over the character values in a string and replace it's value if
 neccessary?
