I'm using ClosedXML elsewhere in my script where I'm iterating through every row like this and it works.
var workbook = new XLWorkbook(ObjectRepPath);
var rows = workbook.Worksheet(1).RangeUsed().RowsUsed().Skip(1);
foreach (var row in rows)
{
objPage = row.Cell(1).GetString();
objElement = row.Cell(2).GetString();
if (objPage == page && objElement == element)
{
locType = row.Cell(3).GetString();
locParm = row.Cell(4).GetString();
}
}
After that I need to pull the data from the cells in a randomly selected row. Here's what I've got so far, which is not working...
var workbook = new XLWorkbook(extFile);
var ws = workbook.Worksheets.Add("Cell Values");
var rnd = new Random();
int rowNum = rnd.Next(2, workbook.Worksheet(1).RangeUsed().RowsUsed().Count());
var dataRow = ws.Row(rowNum);
string dangit = dataRow.Cell(1).GetString();
System.Diagnostics.Debug.WriteLine("Why is this dang thing not working... " + dangit);
Output: Why is this damn thing not working...
It just comes back empty. No error. Does anyone see something I don't?
Alright, I found the solution.
I changed the line ...
var ws = workbook.Worksheets.Add("Cell Values");
to ....
var ws = workbook.Worksheet(1);
and now this works ....
Storage.StreetAddress = ws.Cell(xlRow, 1).GetString();

I know I'm only showing one value from my 'reader' from the database, that's where I got stuck in that I don't know how to specifically pinpoint each cell of my spreadsheet. I'm pulling an unknown recordset size from a database and need to enter it on a google spreadsheet. I know how many columns.
Since I know my columns, I just kept making new CellData(); items for each RowData item in my reader.Read() while looping. Worked first time!
So I'm trying to scrape some website data (specifically the first table here). I am using the table xpath, and trying to get the specific row data assigned to my model.
public static async Task<List<SuspensionModel>> GetSuspensionData()
{
var htmlDocument = new HtmlDocument();
var httpResponseMessage = await _httpClient.GetAsync(_2020SuspUrl);
await EnsureSuccessStatusCode(httpResponseMessage);
var SuspStatsAsHtml = await httpResponseMessage.Content.ReadAsStringAsync();
htmlDocument.LoadHtml(SuspStatsAsHtml);
var suspData = ParseTable(htmlDocument, "/html/body/div[3]/div[3]/div[5]/div[1]/table[1]/tbody/tr");
//return ;
}
private static List<SuspensionModel> ParseTable(HtmlDocument htmlDocument, string xPath)
{
var returnData = new List<SuspensionModel>();
foreach (HtmlNode row in htmlDocument.DocumentNode.SelectNodes(xPath))
{
HtmlNodeCollection cells = row.SelectNodes("td");
var arr = new String[7];
for (int i = 0; i < cells.Count; ++i)
{
arr[i] = cells[i].InnerText;
}
var susp = new SuspensionModel
{
IncidentDate = DateTime.Parse(arr[0]),
OffenderName = arr[1],
OffenderTeam = arr[2],
OffenseDesc = arr[3],
ActionDate = DateTime.Parse(arr[4]),
OffenseLength = arr[5],
SalaryLoss = int.Parse(arr[6])
};
returnData.Add(susp);
}
return returnData;
}
In my ParseTable method, where I am assigning values in my model, how can I access the specific cell data in the given row? Basically, I want to do something like:
foreach row, step through each cell and assign to the correct model value. As I have it now, my cells variable always returns null, so I assume I am not using HtmlAgilityPack correctly.
Any assistance is appreciated here!
I ended up resolving this. I was missing two things, and it turns out it wasn't related to HtmlAgilityPack.
I needed to add .Skip(1) to my foreach row so that it skipped the table header row.
foreach (HtmlNode row in htmlDocument.DocumentNode.SelectNodes(xPath).Skip(1))
I needed to fix my SalaryLoss value. I was assigning it as an int, but I needed to change that to a double as it was a currency value.
SalaryLoss = double.Parse(arr[6], System.Globalization.NumberStyles.Currency)
I have a .csv file structured like so, first row is the header column, for each SomeID I need to add the NetCharges together(or substract if the code calls for it) and put each item into its own column by the SomeCode column.
Heres the file I receive;
SomeID,OrderNumber,Code,NetCharge,Total
23473,30388,LI 126.0000, 132.00
96021, 000111, LI, 130.00, 126.00
23473,30388,FU 6.0000, 132.00
4571A,10452,LI,4100.0000, 4325.0000
4571A,10452,FU,150.00,4325.0000
4571A,10452,DT,75.00,4325.0000
I need to insert the data to my sql table which is structured like this. This is what I'm aiming for:
ID OrderNumber LICode LICodeValue FUCode FUCodeValue DTCode, DTCodeValue, total
23473 30388n LI 126.000 FU 6.0000 NULL NULL 132.0000
4571A 10452 LI 4100.0000 FU 150.0000 DT 75.00 4325.0000
My SomeID will not always be grouped together like the 4571A id is.I basically need to iterate over this file and create one record for each SomeID. I cannot seem to find a way with csvHelper. I'm using C# and csvHelper. I have trid this so far but I cannot get back to the SomeId after passing on to the nexr one:
using (var reader = new StreamReader( "C:\testFiles\some.csv" ))
using (var csv = new CsvReader( reader, CultureInfo.InvariantCulture ))
{
var badRecords = new List<string>();
var isRecordBad = false;
csv.Configuration.HasHeaderRecord = true;
csv.Configuration.HeaderValidated = null;
csv.Configuration.IgnoreBlankLines = true;
csv.Configuration.Delimiter = ",";
csv.Configuration.BadDataFound = context =>
{
isRecordBad = true;
badRecords.Add( context.RawRecord );
};
csv.Configuration.MissingFieldFound = ( s, i, context ) =>
{
isRecordBad = true;
badRecords.Add( context.RawRecord );
};
List<DataFile> dataFile = csv.GetRecords<DataFile>().ToList();
//initialize variable
string lastSomeId = "";
if (!isRecordBad)
{
foreach (var item in dataFile)
{
// check if its same record
if (lastSomeId != item.SomeID)
{
MyClass someClass = new MyClass();
lastSomeId = item.SomeID;
//decimal? LI = 0;//was going to use these as vars for calculations not sure I need them???
//decimal? DSC = 0;
//decimal? FU = 0;
someClass.Id = lastSomeId;
someClass.OrdNum = item.OrderNumber;
if (item.Code == "LI")
{
someClass.LICode = item.Code;
someClass.LICodeValue = item.NetCharge;
}
if (item.Code == "DT")
{
someClass.DTCode = item.Code;
someClass.DTCodeValue = item.NetCharge
}
if (item.Code == "FU")
{
someClass.FUCode = item.Code;
someClass.FUCodeValue = item.NetCharge;
}
someClass.Total = (someClass.LICodeValue + someClass.FUCodeValue);
//check for other values to calculate
//insert record to DB
}
else
{
//Insert into db after maipulation of values
}
}
}
isRecordBad = false;
}//END Using
Any clues would be greatly appreciated. Thank you in advance.
I am trying to export some data to an excel sheet S1 whose data would be shown as Pivoted views in the next two sheets S2 and S3. I am able to create a single pivot and it works perfect. But when I create two pivots, the consequent Excel file renders as corrupt.
By corrupt I mean,
On clicking yes, I get this -
Here is the code I am using to create the pivots -
using XL = ClosedXML.Excel;
...
XL.XLWorkbook wb = new XL.XLWorkbook();
dsData = Session["ExportData"] as DataSet;
var sheet1 = wb.Worksheets.Add("output table");
sheet1.Cell(1, 1).InsertTable(dsData.Tables[0], "output table", true);
// sheet1 is the reference sheet S1
var dataRange = sheet1.RangeUsed();
// First Pivot
XL.IXLWorksheet ptSheet1 = wb.Worksheets.Add("S2");
var pt1 = ptSheet1.PivotTables.AddNew("PivotTable1", ptSheet.Cell(3, 1), dataRange);
pt1.ReportFilters.Add("CX");
pt1.RowLabels.Add("C1");
pt1.RowLabels.Add("C2");
pt1.RowLabels.Add("C3");
pt1.RowLabels.Add("C4");
pt1.ColumnLabels.Add("CL1");
pt1.ColumnLabels.Add("CL2");
pt1.ColumnLabels.Add("CL3");
pt1.Values.Add("V").SummaryFormula = XL.XLPivotSummary.Sum;
// Second Pivot
XL.IXLWorksheet ptSheet2 = wb.Worksheets.Add("S3");
var pt2 = ptSheet2.PivotTables.AddNew("PivotTable2", ptSheet1.Cell(3, 1), dataRange);
pt2.ReportFilters.Add("QQ");
pt2.RowLabels.Add("C1");
pt2.RowLabels.Add("C2");
pt2.ColumnLabels.Add("CL1");
pt2.ColumnLabels.Add("CL2");
pt2.ColumnLabels.Add("CL3");
pt2.Values.Add("V").SummaryFormula = XL.XLPivotSummary.Sum;
C1, C2, C3. C4 and V are the column names in my reference sheet S1.
The issue is caused by a ClosedXML implementation bug.
It can easily be reproduced by using the following snippet (a modified version of their Pivot Tables example) and opening the resulting file in Excel:
static void CreateTestPivotTables(string filePath)
{
var wb = new XLWorkbook();
var wsData = wb.Worksheets.Add("Data");
wsData.Cell("A1").Value = "Category";
wsData.Cell("A2").Value = "A";
wsData.Cell("A3").Value = "B";
wsData.Cell("A4").Value = "B";
wsData.Cell("B1").Value = "Number";
wsData.Cell("B2").Value = 100;
wsData.Cell("B3").Value = 150;
wsData.Cell("B4").Value = 75;
var source = wsData.Range("A1:B4");
for (int i = 1; i <= 2; i++)
{
var name = "PT" + i;
var wsPT = wb.Worksheets.Add(name);
var pt = wsPT.PivotTables.AddNew(name, wsPT.Cell("A1"), source);
pt.RowLabels.Add("Category");
pt.Values.Add("Number")
.ShowAsPctFrom("Category").And("A")
.NumberFormat.Format = "0%";
}
wb.SaveAs(filePath);
}
The bug is located in XLWorkbook_Save.cs - GeneratePivotTables method:
private static void GeneratePivotTables(WorkbookPart workbookPart, WorksheetPart worksheetPart,
XLWorksheet xlWorksheet,
SaveContext context)
{
foreach (var pt in xlWorksheet.PivotTables)
{
var ptCdp = context.RelIdGenerator.GetNext(RelType.Workbook);
var pivotTableCacheDefinitionPart = workbookPart.AddNewPart<PivotTableCacheDefinitionPart>(ptCdp);
GeneratePivotTableCacheDefinitionPartContent(pivotTableCacheDefinitionPart, pt);
var pivotCaches = new PivotCaches();
var pivotCache = new PivotCache {CacheId = 0U, Id = ptCdp};
pivotCaches.AppendChild(pivotCache);
workbookPart.Workbook.AppendChild(pivotCaches);
var pivotTablePart =
worksheetPart.AddNewPart<PivotTablePart>(context.RelIdGenerator.GetNext(RelType.Workbook));
GeneratePivotTablePartContent(pivotTablePart, pt);
pivotTablePart.AddPart(pivotTableCacheDefinitionPart, context.RelIdGenerator.GetNext(RelType.Workbook));
}
}
by the line workbookPart.Workbook.AppendChild(pivotCaches); which adds multiple PivotCaches to workbookPart.Workbook while it's allowed to contain 0 or 1.
With that being said, the only way to fix it is inside the source code by modifying the above method as follows:
private static void GeneratePivotTables(WorkbookPart workbookPart, WorksheetPart worksheetPart,
XLWorksheet xlWorksheet,
SaveContext context)
{
var pivotCaches = workbookPart.Workbook.GetFirstChild<PivotCaches>();
foreach (var pt in xlWorksheet.PivotTables)
{
var ptCdp = context.RelIdGenerator.GetNext(RelType.Workbook);
var pivotTableCacheDefinitionPart = workbookPart.AddNewPart<PivotTableCacheDefinitionPart>(ptCdp);
GeneratePivotTableCacheDefinitionPartContent(pivotTableCacheDefinitionPart, pt);
if (pivotCaches == null)
workbookPart.Workbook.AppendChild(pivotCaches = new PivotCaches());
var pivotCache = new PivotCache { CacheId = (uint)pivotCaches.Count(), Id = ptCdp };
pivotCaches.AppendChild(pivotCache);
var pivotTablePart =
worksheetPart.AddNewPart<PivotTablePart>(context.RelIdGenerator.GetNext(RelType.Workbook));
GeneratePivotTablePartContent(pivotTablePart, pt);
pivotTablePart.PivotTableDefinition.CacheId = pivotCache.CacheId;
pivotTablePart.AddPart(pivotTableCacheDefinitionPart, context.RelIdGenerator.GetNext(RelType.Workbook));
}
}
Update: The good news are that my post triggered a ClosedXML source repository fix by Francois Botha (also credits to petelids who brought it up there), so you can take the code from there until their next release which hopefully will include it.
Try this modification. I made a note where I added an additional line. Also, I think the AddNew() method may have had the wrong worksheet reference? You may have been trying to add a pivot table on top of another one. That may have been the real issue rather than the additional line I added.
using XL = ClosedXML.Excel;
...
XL.XLWorkbook wb = new XL.XLWorkbook();
dsData = Session["ExportData"] as DataSet;
var sheet1 = wb.Worksheets.Add("output table");
sheet1.Cell(1, 1).InsertTable(dsData.Tables[0], "output table", true);
// sheet1 is the reference sheet S1
var dataRange = sheet1.RangeUsed();
PivotCache cache = wb.PivotCaches.Add(dataRange); //---THIS LINE HAS BEEN ADDED---
// First Pivot
XL.IXLWorksheet ptSheet1 = wb.Worksheets.Add("S2");
var pt1 = ptSheet1.PivotTables.AddNew("PivotTable1", ptSheet1.Cell(3, 1), cache);
//Changed ptSheet.Cell... to ptSheet1.Cell...
pt1.ReportFilters.Add("CX");
pt1.RowLabels.Add("C1");
pt1.RowLabels.Add("C2");
pt1.RowLabels.Add("C3");
pt1.RowLabels.Add("C4");
pt1.ColumnLabels.Add("CL1");
pt1.ColumnLabels.Add("CL2");
pt1.ColumnLabels.Add("CL3");
pt1.Values.Add("V").SummaryFormula = XL.XLPivotSummary.Sum;
// Second Pivot
XL.IXLWorksheet ptSheet2 = wb.Worksheets.Add("S3");
var pt2 = ptSheet2.PivotTables.AddNew("PivotTable2", ptSheet2.Cell(3, 1), cache);
//Changed ptSheet1.Cell... to ptSheet2.Cell...
pt2.ReportFilters.Add("QQ");
pt2.RowLabels.Add("C1");
pt2.RowLabels.Add("C2");
pt2.ColumnLabels.Add("CL1");
pt2.ColumnLabels.Add("CL2");
pt2.ColumnLabels.Add("CL3");
pt2.Values.Add("V").SummaryFormula = XL.XLPivotSummary.Sum;
I'm trying to get back 2 unique images form an array. Right now I'm refreshing the page until I get 2 unique images. This is not ideal. How can I modify this code to back 2 unique images with out refreshing the page till it hapens.
Can I do it in this layer or do I need to check for unique numbers in the data layer?
Picture dlPicture = new Picture();
DataTable DTPictures = dlPicture.GetRandomPicture();
Picture dlPicture2 = new Picture();
DataTable DTPictures2 = dlPicture2.GetRandomPicture();
// the variables to hold the yes and no Id's for each set
string firstNoPicId = "";
string firstYesPicId = "";
string secondNoPicId = "";
string secondYesPicId = "";
foreach (DataRow row in DTPictures.Rows)
{
firstYesPicId = row["PicID"].ToString();
secondNoPicId = firstYesPicId;
FirstPicMemberNameLabel.Text = row["MemberName"].ToString();
FirstPicLink.ImageUrl = "Pictures/" + row["PicLoc"];
}
foreach (DataRow row in DTPictures2.Rows)
{
secondYesPicId = row["PicID"].ToString();
firstNoPicId = secondYesPicId;
SecondPicMemberNameLabel.Text = row["MemberName"].ToString();
SecondPicLink.ImageUrl = "Pictures/" + row["PicLoc"];
}
if (firstYesPicId != secondYesPicId)
{
FirstPicLink.PostBackUrl = "default.aspx?yesId=" + firstYesPicId + "&noId=" + firstNoPicId;
SecondPicLink.PostBackUrl = "default.aspx?yesId=" + secondYesPicId + "&noId=" + secondNoPicId;
}
else
{
Response.Redirect("Default.aspx");
}
There two pretty obvious ways to deal with this
Add an overload dlPicture.GetRandomPicture(int picID) This will accept an ID so that it won't return an already used picID
restructure your code so that it loops until the secondYesPicId != firstYesPicId
Something like
secondYesPicId = firstYesPicId;
while (firstYesPicId == secondYesPicId)
{ DataTable DTPictures2 = dlPicture2.GetRandomPicture();
foreach (DataRow row in DTPictures2.Rows)
{
secondYesPicId = row["PicID"].ToString();
SecondPicMemberNameLabel.Text = row["MemberName"].ToString();
SecondPicLink.ImageUrl = "Pictures/" + row["PicLoc"];
}
}
Perhaps a better solution would be adding code to your datalayer.GetRandomPicture to make sure it can't return the same picture twice in a row?
in this Picture class add a LastRandomPictureID variable and do a 'WHERE NOT ID = LastRandomPictureID' on your query (you might want to make it a bit more robust to handle the case where only 1 picture exists).
var rnd = new Random();
int randomPicIndex1 = rnd.Next(numOfPictures);
int randomPicIndex2;
do {
randomPicIndex2 = rnd.Next(numOfPictures);
} while (randomPicIndex1 == randomPicIndex2);
Then use these indexes in order to get random rows from your table.
DataRow row1 = DTPictures.Rows[randomPicIndex1];
DataRow row2 = DTPictures.Rows[randomPicIndex2];
