How to retrieve data from text file

I have data appended line by line in a text file for all confirmed transaction. I want to add Search functionality, where the user enters their E-mail address and all related transaction details connected to that E-mail must be displayed.
bool writeNextLine = false;
StringBuilder sb = new StringBuilder();
// Read the file and display it line by line.
using (System.IO.StreamReader file = new System.IO.StreamReader("record.txt"))
{
while ((line = file.ReadLine()) != null)
{
if (line.Contains(txt_SearchBooking.Text))
{
// This append the text and a newline into the StringBuilder buffer
sb.AppendLine(line.ToString());
lbl_result.Text += sb.ToString();
}
}
}
but only the line containing Email is displayed other details are not.
Email is located on the last line of every transaction detail.
confirmmsg =
" Transaction # : " + EmployeeIDTextBox.Text + ClientIDTextBox.Text + UniqueIDTextBox.Text + "\r\n"
+ " First Name : " + ClientFirstNameTextBox.Text + "\r\n"
+ " Telephone Number : " + ClientTelephoneNumberTextBox.Text + "\r\n"
+ " Investment : " + investmentamt.ToString("C2") + "\r\n"
+ " Interest : " + (twelvemonthint * 100).ToString() + "%" + "\r\n"
+ " Interest Amount : " + (invesmentcalc(investmentamt, twelvemonthterm, twelvemonthint) - investmentamt).ToString("C2") + "\r\n"
+ " Bonus : " + bonus.ToString("c2") + "\r\n"
+ " Total Returns : " + invesmentcalc(investmentamt, twelvemonthterm, twelvemonthint).ToString("C2") + "\r\n"
+ " E-mail : " + ClientEmailTextBox.Text;
This is the data which is written into the text file.

If you always have 9 lines per transaction, with email being the last line, you could use File.ReadAllLines and a counter.
var lines = File.ReadAllLines("records.txt");
for(int i = 0; i < lines.Length; i++)
{
var line = lines[i];
if(line.Contains(txt_SearchBooking.Text))
{
//Retrieve the previous lines
for(int y = i-8; y <= i; y++)
{
lbl_result.Text += lines[y];
}
}
}

Merge 2 TSV files in C# code cleanup

I'm provided with 2 Excel files that I convert to TSV files and in the end have to deliver in a TSV file. The 1st file is the main file (strWorksheetPath) and all lines have to be included. The 2nd file (PrintPath) has additional information but not each line in the main file has extra information. To do this in C# I followed this msdn guide to do what I have to do and it's working fine. Unfortunatly, file 1 has 23 columns and file 2 has 10 adding up to 33 columns and so 33 properties in total. I created some temp classes to see if everything is working but it looks very messy in my opinion.
Is there a way to clean up my code and make it look more tidy by possibly not having to make temp classes, condense some repetitive code, ...?
public static void ConvertTSVtoMontDataTable(string strWorksheetPath, string strPrintPath,
bool closeConnection = true)
{
// Check if the main file exist.
if (!File.Exists(strWorksheetPath)) return;
// Load both files.
var mainFile = File.ReadAllLines(strWorksheetPath);
var extraFile = File.ReadAllLines(strPrintPath);
// Create 2 lists.
var mainLines = mainFile.Select(line => new TempMainLine(line)).ToList();
var extraLines = extraFile.Select(line => new TempExtraLine(line)).ToList();
var lines = new List<TempLine>();
// Merge both files.
var leftOuterJoinQuery =
from worksheetLine in mainLines
join printLine in extraLines on string.Concat(worksheetLine.prop6, worksheetLine.prop8) equals
string.Concat(printLine.prop4, printLine.prop5) into lineGroup
from line in lineGroup.DefaultIfEmpty()
select
new TempLine(worksheetLine.prop0, worksheetLine.prop1, worksheetLine.prop2, worksheetLine.prop3,
worksheetLine.prop4, worksheetLine.prop5, worksheetLine.prop6, worksheetLine.prop7,
worksheetLine.prop8, worksheetLine.prop9, worksheetLine.prop10, worksheetLine.prop11,
worksheetLine.prop12, worksheetLine.prop13, worksheetLine.prop14, worksheetLine.prop15,
worksheetLine.prop16, worksheetLine.prop17, worksheetLine.prop18, worksheetLine.prop19,
worksheetLine.prop20, worksheetLine.prop21, worksheetLine.prop22, line == null ? "" : line.prop0,
line == null ? "" : line.prop1, line == null ? "" : line.prop2, line == null ? "" : line.prop3,
line == null ? "" : line.prop4, line == null ? "" : line.prop5, line == null ? "" : line.prop6,
line == null ? "" : line.prop7, line == null ? "" : line.prop8, line == null ? "" : line.prop9);
foreach (var tempLine in leftOuterJoinQuery)
{
lines.Add(tempLine);
}
// Write output to new temp file (TESTING)
using (
var file =
new StreamWriter(Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location),
"output.txt")))
{
foreach (var item in lines)
{
file.WriteLine(item.prop0 + (char)9 + item.prop1 + (char)9 + item.prop2 + (char)9 + item.prop3 +
(char)9 + item.prop4 + (char)9 + item.prop5 + (char)9 + item.prop6 + (char)9 +
item.prop7 + (char)9 + item.prop8 + (char)9 + item.prop9 + (char)9 + item.prop10 +
(char)9 + item.prop11 + (char)9 + item.prop12 + (char)9 + item.prop13 + (char)9 +
item.prop14 + (char)9 + item.prop15 + (char)9 + item.prop16 + (char)9 +
item.prop17 + (char)9 + item.prop18 + (char)9 + item.prop19 + (char)9 +
item.prop20 + (char)9 + item.prop21 + (char)9 + item.prop22 + (char)9 +
item.prop23 + (char)9 + item.prop24 + (char)9 + item.prop25 + (char)9 +
item.prop26 + (char)9 + item.prop27 + (char)9 + item.prop28 + (char)9 +
item.prop29 + (char)9 + item.prop30 + (char)9 + item.prop31 + (char)9 +
item.prop32);
}
}
}

I thought about this some more and regardless of what your Temp* classes look like, something along the lines of the below will work given the assumption that (based on the code you presented), you're outputting every column from both files in the order in which they came in. If you needed to exclude fields, change the order, etc., that would require some changes to the below or a different solution entirely.
It's basically just reading those two files in, joining on the Split() result and then combining the two lines. I didn't see a point in handling the LOJ logic for a null printFile line but if you need the extra tabs, you could replace the line ?? "" with something like line ?? new String('\t', 10)
Note that this is probably not the most efficient way to go about this and if your files are huge, you'd definitely want to optimize this a bit.
// Merge both files.
var lines =
from worksheetLine in mainFile
join printLine in extraFile on string.Concat(worksheetLine.Split('\t')[6], worksheetLine.Split('\t')[8]) equals
string.Concat(printLine.Split('\t')[4], printLine.Split('\t')[5]) into lineGroup
from line in lineGroup.DefaultIfEmpty()
select string.Concat(worksheetLine, line ?? "");
// Write output to new temp file (TESTING)
using (
var file =
new StreamWriter(Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location),
"output.txt")))
{
foreach (var item in lines)
{
file.WriteLine(item);
}
}

Deleting files inside folder in C#

GetFiles of certain extension and write to spreadsheet C#

Just to make it clear what I think you are asking...
You currently get this for each line:
2 vehicle control services ltd brom mal
but you want it like this for each line (which let me point out makes absolutely no sense at all, it doesn't look very usable):
2vehicle control services ltdBromMlkit
If that is the case then in your code just replace this line:
swFile.WriteLine(string.Join(" ", colData));
with this line:
swFile.WriteLine(string.Join("", colData));
Notice that it will now join the string with an empty string, rather than joining with the single space that you don't want.
