Parsing through a pipe delimited File

Hello Everyone,

In the sample code I supplied, I and using a StreamReader to read a pipe delimited file. A sample of the file looks like this:

11517838|05   |F |01|2041|Y|0.1500|N| \n 11517838|05   |F |01|2042|Y|0.1500|N| \n11517838|05   |F |01|2044|Y|0.1500|N| \n11517838|05   |F |01|2047|Y|0.1500|N| \n11517838|05   |F |01|2049|Y|0.1500|N| \n

In the file, they are all on one line, with the newline character after the |N|. What I need to be able to do, is read the whole file into a string array like I have shown, but then I need to go 'line' by 'line' to populate some string variables. Right now when I run my code, it will go in and get the first:

11517838|05   |F |01|2041|Y|0.1500|N|

from the file, but when it goes in for the second iteration, It does not move to the next line, aka, the character after the newline mark. Thanks in advance for your help.
StreamReader sr = new StreamReader(dailyAudit.ToString());
                        auditLine = sr.ReadToEnd();
                        string auditContents = auditLine;
                        string[] lines = auditContents.Split(char.Parse("|"));
                        int x = 1;
                        
                        while (x < lines.Length && lines[x].ToString() != "\n")
                       {
                            x++;
                            string MID = lines[0];
                            string Vendor = lines[1];
                            string VendType = lines[2];
                            string CardID = lines[3];
                            string ChargeType = lines[4];
                            string RateType = lines[5];
                            string Amount = lines[6];
                            string ExcessRol = lines[7];
                            string FileDate = ftpDate;
                       }

Instead of this
you use streamreader to read the file
and then use object of streamreader srObj.ReadLine() to read line by line

So, I could change the code to look like:
StreamReader sr = new StreamReader(dailyAudit.ToString());
                        auditLine = sr.ReadLine();
                        string auditContents = auditLine;
                        string[] lines = auditContents.Split(char.Parse("|"));
                        while (sr.ReadLine() != null)
                       {
                            string MID = lines[0];
                            string Vendor = lines[1];
                            string VendType = lines[2];
                            string CardID = lines[3];
                            string ChargeType = lines[4];
                            string RateType = lines[5];
                            string Amount = lines[6];
                            string ExcessRol = lines[7];
                            string FileDate = ftpDate;

                       }

Edit to that last code sample:

while (sr.ReadLine() != null)
                       {    
                            string auditContents = auditLine;
                            string[] lines = auditContents.Split(char.Parse("|"));
                           
                            string MID = lines[0];
                            string Vendor = lines[1];
                            string VendType = lines[2];
                            string CardID = lines[3];
                            string ChargeType = lines[4];
                            string RateType = lines[5];
                            string Amount = lines[6];
                            string ExcessRol = lines[7];
                            string FileDate = ftpDate;

                       }

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

So I totally changed my code to read as you see below. Problem is that it still won't move on to the next line in the file.
while (sr.ReadLine() != null)
                        {
                            string[] lines = sr.ReadLine().Split(char.Parse("|"));

                            string MID = lines[0];
                            string Vendor = lines[1];
                            string VendType = lines[2];
                            string CardID = lines[3];
                            string ChargeType = lines[4];
                            string RateType = lines[5];
                            string Amount = lines[6];
                            string ExcessRol = lines[7];
                            string FileDate = ftpDate;
                        }

Use it like below:


while (true)
                        {
string aLine = sr.ReadLine();
if(aLine == null) break;

                            string[] lines = aLine.Split("|");

                            string MID = lines[0];
                            string Vendor = lines[1];
                            string VendType = lines[2];
                            string CardID = lines[3];
                            string ChargeType = lines[4];
                            string RateType = lines[5];
                            string Amount = lines[6];
                            string ExcessRol = lines[7];
                            string FileDate = ftpDate;
                        }

You can use File.ReadAllLines to get a string array, where each item in the array represents one line in the file.  Then loop through that array, and split each individual line on the | character to get the fields.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main(string[] args)
		{
			string[] lines = File.ReadAllLines("C:\\test.txt");

			foreach (string line in lines)
			{
				string[] fields = line.Split('|');

				string one = fields[0];
				string two = fields[1];
				string three = fields[2];
				string four = fields[3];
			}
		}
	}
}

Sorry...didn't catch that your using a StreamReader on a string variable.  If File.ReadAllLines doesn't work in your case, you can just use Split('\n') on dailyAudit.ToString().
...what is dailyAudit?  Maybe the problem is that dailyAudit only has one line in it?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main(string[] args)
		{
			string dailyAudit = "The|Quick|Brown|Fox\nJumped|Over|The|Lazy\nDog|Hello|World|Test\n";

			string[] lines = dailyAudit.ToString().Split('\n');

			foreach (string line in lines)
			{
				string[] fields = line.Split('|');

				string one = fields[0];
				string two = fields[1];
				string three = fields[2];
				string four = fields[3];
			}
		}
	}
}
