Trying to properly set up query for match of 2 csv files got stuck

Here's an example of what the data looks like on each csv.
inventory.csv
ID, payment, Receipt#
90006, VISA, jk73kl_
90006, VISA, null
inventory.csv
INFO, VIEWS, DATE
9006_Produce_Banana_jk73kl__, 0, 10-13-20
9006_Produce_Banana, 0, 10-13-20
I am having trouble with my where, I need to search both forms and if there is a matching receipt number pull them out and combine the two rows.
using System;
using System.Collections.Generic;
using System.Linq;
namespace ConsoleApp1
{
class Program
{
static void Main()
{
string[] ourDataSheet = System.IO.File.ReadAllLines(#"../../OurData.csv");
string[] theirDataSheet = System.IO.File.ReadAllLines(#"../../TheirData.csv");
string ourDataHeaders = ourDataSheet[0];
string theirDataHeaders = theirDataSheet[0];
IEnumerable<string> TrackingQuery =
from ourData in ourDataSheet
let ourDataFields = ourData.Split(',')
from theirData in theirDataSheet
let theirDataFields = theirData.Split(',')
where theirDataFields[0].EndsWith(ourDataFields[2])
select ourDataFields[0] + "," + ourDataFields[1] + "," + ourDataFields[2] + "," + theirDataFields[0] + "," + theirDataFields[0] + "," + theirDataFields[1] + "," + theirDataFields[2] + "," + theirDataFields[3];
OutPutResults(TrackingQuery);
Console.ReadKey();
}
static void OutPutResults(IEnumerable<string> query)
{
foreach(string item in query)
{
Console.WriteLine(item);
Console.Read();
}
}
}
}

First things first, I would recommend that you use a third-party package like CsvHelper and do something like the following
public class Sale
{
public int ID { get; set; }
public string Payment { get; set; }
[Name("Recipt#")]
public string Recipt { get; set; }
}
public class Inventory
{
public string INFO { get; set; }
public string VIEWS { get; set; }
public string DATE { get; set; }
}
IEnumerable<Sale> sales;
IEnumerable<Inventory> inventory;
using (var reader = new StreamReader(#"../../OurData.csv"))
using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
{
sales = csv.GetRecords<Sale>();
}
using (var reader = new StreamReader(#"../../TheirData.csv"))
using (var csv = new CsvReader(reader, CultureInfo.InvariantCulture))
{
inventory = csv.GetRecords<Inventory>();
}
var results = sales.Where(s => inventory.Any(i => i.INFO.EndsWith(s.Recipt)));

Set DeserializeObject in anonymous property of a class

I have this:
public class ComponentData
{
public dynamic CdHtml { get; set; }
public dynamic CdJson { get; set; }
public dynamic CdSection { get; set; }
public dynamic CdContainer { get; set; }
public dynamic CdRow { get; set; }
public dynamic CdContainerId { get; set; }
public dynamic CdColsJson { get; set; }
}
And i want to set the ComponentData Class with these values but i get an error:
var componentData = new ComponentData()
{
CdHtml = obj.htmlCD,
CdJson = JsonConvert.DeserializeObject<dynamic>(obj.jsonCD),
CdContainerId = "SECTION" + obj.CD_Container_Id,
CdSection = JsonConvert.DeserializeObject<dynamic>(pc.Build_CDxxxJson("xxx" + obj.CD_Container_Id, "width:" + tlj.width.ToString() + "%;padding-left:30px;padding-right:30px;padding-top:30px;padding-bottom:30px;" + sectionCenterStyle, "section")),
CdContainer = JsonConvert.DeserializeObject<dynamic>(pc.Build_CDxxxJson("xxx" + obj.divGUID2, containerStyle, "container")),
CdRow = JsonConvert.DeserializeObject<dynamic>(pc.Build_CDxxxJson("xxx" + obj.divGUID3, "", "row")),
CdColsJson = JsonConvert.DeserializeObject<dynamic>(pc.Build_CDxxxJson(obj.divGUID4, "", string.Format("col-xs-{0} col-sm-{1} col-md-{2} col-lg-{3} hoversel colregion{4}", bsc.xs, bsc.sm, bsc.md, bsc.lg, obj.divGUID4), bsc.xs, bsc.sm, bsc.md, bsc.lg))
};
return Json(new { componentData = componentData, html = obj.html });
how would i return this class with the json objects inside and pass it back to the client using ajax?

Change your code to this:
var componentData = new ComponentData()
{
CdHtml = obj.htmlCD,
CdJson = JsonConvert.DeserializeObject<ExpandoObject>(obj.jsonCD),
CdContainerId = "SECTION" + obj.CD_Container_Id,
CdSection = JsonConvert.DeserializeObject<ExpandoObject>(pc.Build_CDxxxJson("xxx" + obj.CD_Container_Id, "width:" + tlj.width.ToString() + "%;padding-left:30px;padding-right:30px;padding-top:30px;padding-bottom:30px;" + sectionCenterStyle, "section")),
CdContainer = JsonConvert.DeserializeObject<ExpandoObject>(pc.Build_CDxxxJson("xxx" + obj.divGUID2, containerStyle, "container")),
CdRow = JsonConvert.DeserializeObject<ExpandoObject>(pc.Build_CDxxxJson("xxx" + obj.divGUID3, "", "row")),
CdColsJson = JsonConvert.DeserializeObject<ExpandoObject>(pc.Build_CDxxxJson(obj.divGUID4, "", string.Format("col-xs-{0} col-sm-{1} col-md-{2} col-lg-{3} hoversel colregion{4}", bsc.xs, bsc.sm, bsc.md, bsc.lg, obj.divGUID4), bsc.xs, bsc.sm, bsc.md, bsc.lg))
};
If you want to convert to dynamic you need to use ExpandoObject just as you would use when you want to create one with your hands.

How Can I Create One xml file with Multiple XML douments inside from a text file

I am a C# beginner programmer. I have a text file, which is my source, with multiple rows of data. I want to create one xml file with multiple xml documents inside the file. The xml documents are generated from the rows of data in the text file. I can only get one xml document to generate in the A0x.xml file that is created. My code only reads the first row of data and generates one xml document instead to multiple xml documents. Below are 8 rows from the M24EX.txt file. Please help!!

Using Apache Lucene to search

I've been trying to implement Lucene to make the searching on my website faster.
My code currently works, however, I think I am not correctly making use of Lucene. Right now, my search query is productName:asterisk(input)asterisk - I can't imagine this is what you're supposed to do to find all products where productName contains input. I think it has something to do with the way I save the fields to a document.
My code:

Any help would be greatly appreciated.
Example input list of products:
Query:
SELECT Product.ID, Product.Decription, Product.Name FROM Product
Desired results:
SQL Server query equivalent:
SELECT Product.ID, Product.Decription, Product.Name FROM Product WHERE Product.Name LIKE '%Zelf%' OR Product.Decription LIKE '%Zelf%'
Basically, Zelf is the input. I want to find all matches with product descriptions or product names that contain the input string.

ucene not allows to use ? or * as starting symbols of the searching term. To overcome this issue you need to store in your index a sub-strings from any position of word to it end position. E.g. for word test you should put to index
test
est
st
t
I recommend to use separate field for that. Java example for case if you have a short field with one word like a product name.
for(int i = 0; i < product.SafeName.length()-1; i++){
Field productTitleSearchField = new Field("productNameSearch", product.SafeName.substring(i, product.SafeName.length()), Field.Store.NO, Field.Index.ANALYZED);
}
After this you can use following query string
productNameSearch:(input)asterisk or use a PrefixQuery for searching product names containing input.
In case if you have several words in you field and for you will be enough to have some reasonable length of your input, then it will better to add for this field a NGramTokenFilter. You if have limit on your input string from n to m you should create a NGram Token Filter with n minGram and m maxGramm. If you has word test and you limit 2 to 3 you will have in your index words
te
tes
es
est
st
After this you can search via string

This doesn't answer your question but it is safer to use the using block in C#. In your current code, calling dispose can throw.
You're doing:
IndexReader reader = IndexReader.Open(GetCurrentDirectory(), true);
Searcher searcher = new IndexSearcher(reader);
Analyzer analyzer = new StandardAnalyzer(Version);
//...
reader.Dispose();
searcher.Dispose();
analyzer.Dispose();
Which can be replaced with:
using (IndexReader reader = IndexReader.Open(GetCurrentDirectory(), true))
using (Searcher searcher = new IndexSearcher(reader))
using (Analyzer analyzer = new StandardAnalyzer(Version))
{
//Do whatever else here.. No need to call "dispose".
}
The above is pretty much a try -> finally statement where it tries to do whatever is in the using statement. If anything throws, the finally block disposes the resources opened/allocated.
Another way (comma operator.. if all variables are of the same type) is:
using (whatever foo = new whatever(), whatever bar = new whatever(), ...)
{
//do whatever here..
}

Remove/Replace comma from CSV file when using entity framework?

I have come across this issue and I can't solve it and it's driving me insane. I've created an C# app that reads a csv file, then inserts the information into MSSQL. When I do this though, I'm getting some skewed inserts. Everything inserts fine until there is a comma within double quotes.. for example, if the Bank Name is "Capital One,Inc" it will insert 'Inc' into the next column. I have tried removing the comma's, but I'm getting the same results. I am using the entity framework to do this.. this is how my dataclass is set up.
namespace CIT
{
class RawData
{
public string Branch { get; set; }
public string Pfx { get; set; }
public string AcctNo { get; set; }
public string CustName { get; set; }
public string CtrlNo { get; set; }
public string RefNo { get; set; }
public string Days { get; set; }
public string DealNoCat { get; set; }
public string BankNameFiCat { get; set; }
public string FinMgrName { get; set; }
public string Desc { get; set; }
public string DealDateCat { get; set; }
public string SchedNo { get; set; }
public string SchedTypeDv { get; set; }
public string SchedRemarks { get; set; }
public string Amt { get; set; }
public string Src { get; set; }
public string SysDateCat { get; set; }
public string JrnlDateDv { get; set; }
public string DateY4 { get; set; }
public string DaysOut { get; set; }
public RawData(string csvString)
{
string[] citData = csvString.Replace(", ", " ").Replace(".", " ").Split(',');
try
{
Branch = citData[0].Replace("\"", "");
Pfx = citData[1].Replace("\"", "");
AcctNo = citData[2].Replace("\"", "");
CustName = citData[3].Replace("\"", "");
CtrlNo = citData[4].Replace("\"", "");
RefNo = citData[5].Replace("\"", "");
Days = citData[6].Replace("\"", "");
DealNoCat = citData[7].Replace("\"", "");
BankNameFiCat = citData[8].Replace("\"", "");
FinMgrName = citData[9].Replace("\"", "");
Desc = citData[10].Replace("\"", "");
DealDateCat = citData[11].Replace("\"", "");
SchedNo = citData[12].Replace("\"", "");
SchedTypeDv = citData[13].Replace("\"", "");
SchedRemarks = citData[14].Replace("\"", "");
Amt = citData[15].Replace("\"", "");
Src = citData[16].Replace("\"", "");
SysDateCat = citData[17].Replace("\"", "");
JrnlDateDv = citData[18].Replace("\"", "");
DateY4 = citData[19].Replace("\"", "");
DaysOut = null;
}
catch (Exception ex)
{
Console.WriteLine("Something went wrong. " + ex.ToString());
}
}
}
}
I have also tried
BankNameFiCat = citData[8].Replace(",", " ").Replace("\"", "");
but I have no had any luck with that. I think the problem is that the comma has no spaces before or after it. It is like "Capital One,Inc" and it's like that with other bank names as well.
This is how I'm uploading the file to the list then writing it to the db..
string text = File.ReadAllText(lblFileName.Text);
string[] lines = text.Split('\n');
int total = 0, reduced = 0;
foreach (string line in lines)
{
RawData temp = new RawData(line);
total++;
if (!(temp.Branch.Length == 0 || temp.Branch == "Branch"))
{
reduced++;
data.Add(temp);
}
}
Linq/Entity
foreach (RawData rData in data)
{
tFIManager fimanag;
tBank bank;
tCustomer cust;
fimanag = (context.tFIManagers.Any(fimanager => fimanager.FIName == rData.FinMgrName) ? context.tFIManagers.Where(fimanager => fimanager.FIName == rData.FinMgrName).FirstOrDefault() : context.tFIManagers.Add(new tFIManager { FIName = rData.FinMgrName }));
bank = (context.tBanks.Any(banks => banks.BankName == rData.BankNameFiCat) ? context.tBanks.Where(banks => banks.BankName == rData.BankNameFiCat).FirstOrDefault() : context.tBanks.Add(new tBank { BankName = rData.BankNameFiCat }));
cust = (context.tCustomers.Any(custs => custs.CustomerName == rData.CustName) ? context.tCustomers.Where(custs => custs.CustomerName == rData.CustName).FirstOrDefault() : context.tCustomers.Add(new tCustomer { CustomerName = rData.CustName }));
DateTime DateY4, DealDate, SysDate, JrnlDate;
bool hasDate = DateTime.TryParse(rData.DateY4, out DateY4);
bool hasDeal = DateTime.TryParse(rData.DealDateCat, out DealDate);
bool hasSys = DateTime.TryParse(rData.SysDateCat, out SysDate);
bool hasJrnl = DateTime.TryParse(rData.JrnlDateDv, out JrnlDate);
decimal amt;
bool hasAmt = Decimal.TryParse(rData.Amt, out amt);
tContractsInTransit cit = new tContractsInTransit
{
Branch = rData.Branch,
Pfx = rData.Pfx,
AcctNo = rData.AcctNo,
CustomerID = cust.CustomerID,
CtrlNo = rData.CtrlNo,
RefNo = rData.RefNo,
Days = rData.Days,
DealNoCat = rData.DealNoCat,
BankID = bank.BankID,
FIManagerID = fimanag.FIManagerID,
Desc = rData.Desc,
DealDateCat = null,
SchedNo = rData.SchedNo,
SchedTypeDv = rData.SchedTypeDv,

};
if (hasDeal)
{
cit.DealDateCat = DealDate;
}
if (hasSys)
{
cit.SysDateCat = SysDate;
}
if (hasJrnl)
{
cit.JrnlDateDv = JrnlDate;
}
if (hasDate)
{
cit.DateY4 = DateY4;
}
context.tContractsInTransits.Add(cit);
context.SaveChanges();
}
context.Dispose();
I'm not sure what else to try.. I probably am just tired of looking at it at this point. Thanks in advance!

Just find commas in quotes and replace them prior to doing anything else. You could probably use the code from one of the answers in this question.

Use Microsoft.ACE.OLEDB.12.0 to read Excel file. This should solve your problem.
public static DataSet ReadFile(string file)
{
string connstring = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + file + ";Extended Properties='text;HDR=YES;FMT=Delimited';";
string sql = "select * from " + name;
DataSet ds = null;
Using (OleDbConnection conn = new OleDbConnection(connstring))
{
conn.Open();
using (OleDbDataAdapter myCommand = new OleDbDataAdapter(strSql, connstring))
{
ds = new DataSet();
myCommand.Fill(ds, "table1");
}
}
return ds;
}
