EPPlus Pivot table SubTotalFunctions produces spreadsheet error

I am creating a pivot table to with data. I create a RowField and attempt to add a SubTotalFunctions to that field.
When I open the .xlsx file, I get an error that says the file needs to be repaired.
Is this a bug or is there another option that I should be setting?
using OfficeOpenXml;
using OfficeOpenXml.Table.PivotTable;
var data = Datas();
var stream = new FileStream("Data.xlsx", FileMode.Create);
// Create the spread sheet package
var pkg = new ExcelPackage(stream);
var wsData = pkg.Workbook.Worksheets.Add("Data");
var wsPivot = pkg.Workbook.Worksheets.Add("Pivot Table");
var dataRange = wsData.Cells["A1"].LoadFromCollection(data, true);
// Create the pivot table
var pivotTable = wsPivot.PivotTables.Add(wsPivot.Cells["A1"], wsData.Cells[1,1,dataRange.End.Row, 3], "Pivot Table");
pivotTable.DataFields.Add(pivotTable.Fields[0]); // FirstNumber
var r = pivotTable.RowFields.Add(pivotTable.Fields[1]); // SecondNumber
pivotTable.ColumnFields.Add(pivotTable.Fields[2]); // Text
r.SubtotalTop = true;
r.SubTotalFunctions = eSubTotalFunctions.Sum;
r.Sort = eSortType.Ascending;
r.Compact = true;
r.Outline = true;
pkg.Save();
stream.Flush();
stream.Close();

How to fill picker with a list

I am updating older code but part of it must stay the same. I have now picker that needs to be filled with list.
My list
public List<TimeoutBetweenSentences> FillTimoutOptions()
{
var newListTimeoutBetweenSentenceses = new List<TimeoutBetweenSentences>()
{
new TimeoutBetweenSentences()
{
Position = 0,
Text = "+ 0 sekund",
Value = 0
},
new TimeoutBetweenSentences()
{
Position = 1,
Text = "+ 1 sekunda",
Value = 1
},
new TimeoutBetweenSentences()
{
Position = 2,
Text = "+ 2 sekundy",
Value = 2
},
new TimeoutBetweenSentences()
{
Position = 3,
Text = "+ 3 sekundy",
Value = 3
},
new TimeoutBetweenSentences()
{
Position = 4,
Text = "+ 4 sekundy",
Value = 4
},
new TimeoutBetweenSentences()
{
Position = 5,
Text = "+ 5 sekund",
Value = 5
},
};
return newListTimeoutBetweenSentenceses;
}
List<TimeoutBetweenSentences> allOptions = FillTimoutOptions();
sentencePausesStepper.Items.Add(allOptions.Select(m => m.Text).ToList().ToString());
however this displays just as "System collections" DO zou have any idea?

this is adding an entire list as ONE element
sentencePausesStepper.Items.Add(allOptions.Select(m => m.Text).ToList().ToString());
to add elements of one list to another, use AddRange instead
sentencePausesStepper.Items.AddRange(allOptions.Select(m => m.Text).ToList().ToString());
or better, do this
sentencePausesStepper.ItemsSource = allOptions;
sentencePausesStepper.ItemDisplayBinding = new Binding("Text");

c# filling up empty records

need some help with my foreach to recongonize the empty record and fill the gap with "-";
let's say we have 30min, 45min, 90min, 120min and not 60min in the case:
It can count the total records of each id, let's say the maximum is 5, 30min, 45min, 60min, 90min and 120min.
if there are 3, then it could check which is missing and than can fill with "-".
Same ideia of the script.
List<Treatment> treatment = new List<Treatment>();
treatment.Add(new Treatment { id = 1, treatmentNameId = 11, duration = "30", price = 30 });
treatment.Add(new Treatment { id = 1, treatmentNameId = 11, duration = "45", price = 45 });
treatment.Add(new Treatment { id = 1, treatmentNameId = 11, duration = "60", price = 60 });
treatment.Add(new Treatment { id = 1, treatmentNameId = 2, duration = "30", price = 30 });
//treatment.Add(new Treatment { id = 1, treatmentNameId = 2, duration = "45", price = 45 });
treatment.Add(new Treatment { id = 1, treatmentNameId = 2, duration = "60", price = 60 });
var newList = (from t in treatment
select t)
.AsQueryable().ToList();
List<List> newList= new List<List>();
foreach (var item in newList)
{
if (item.duration == "30")
{
newList.Add(new List { treatmentNameId = item.treatmentNameId, thirtyMin = "30" });
}
if (item.duration == "45")
{
newList.Add(new List { treatmentNameId = item.treatmentNameId, fortyFive= "45" });
}
if (item.duration == "60")
{
newList.Add(new List { treatmentNameId = item.treatmentNameId, sixty= "60" });
}
}
The end result should like something as,
id:1 30, 45, 60, -
id:2 30, - , 60, 90
id:3 - , 45, -, 90
etc...
Many many thanks for the help.

I'm not going to provide a very detailed explanation of all this, but conceptually I'm just grouping by treatmentNameId and then doing something very similar to an outer join in SQL. If the group join comes up empty for the duration, I'm selecting '-' instead of the duration. Using anonymous types for brevity.
var durations = new[] {"15", "30", "45", "60"};
var results = treatments
.GroupBy(t => t.treatmentNameId).Select(group => new
{
treatmentNameId = group.Key,
durations = durations.GroupJoin(group, s => s, g => g.duration,
(s, grouping) => !grouping.Any() ? "-" : s)
});
foreach (var result in results)
{
Console.WriteLine(result.treatmentNameId + ": " + string.Join(", ", result.durations));
}
This results in:
11: -, 30, 45, 60
2: -, 30, -, 60
If you have problems with something more specific, I'd be happy to explain further.

C# dynamic tree with many parameters, how to do it?

I am trying to fill a tree with more than one parameter (points and types) and at the end, show which "branch" has the max of points and in every branch, show how many equal tupe I have.
The tree will be something like this:
FATHER (Points:200|Type:2)
|_CHILD01 (P:120|Type:3)
| |_CHILD4 (P:300|T:3)
| | |_CHILD8 (P:220|T:3)
| | |_CHILD9 (P:65|T:1)
| |_CHILD5 (P:15|T:9)
|_CHILD2 (P:10|T:1)
|_CHILD3 (P:80|T:2)
|_CHILD6 (P:25|T:2)
| |_CHILD10 (P:110|T:7)
| |_CHILD11 (P:195|T:3)
|_CHILD7 (P:50|T:7)
and what I am trying to get is:
NUMBER OF POINTS PER BRANCH:
Branch01 -> FATHER (200), CHILD01 (120), CHILD04 (300), CHILD08 (220) -> TotalPoints: 840
Branch02 -> FATHER (200), CHILD01 (120), CHILD04 (300), CHILD09 (65) -> TotalPoints: 685
Branch03 -> FATHER (200), CHILD01 (120), CHILD05 (15) -> TotalPoints: 335
Branch04 -> FATHER (200), CHILD02 (10) -> TotalPoints: 210
Branch05 -> FATHER (200), CHILD03 (80), CHILD06 (25), CHILD10 (110) -> TotalPoints: 415
Branch06 -> FATHER (200), CHILD03 (80), CHILD06 (25), CHILD11 (195) -> TotalPoints: 500
Branch07 -> FATHER (200), CHILD03 (80), CHILD07 (50) -> TotalPoints: 330
and
COUNT THE NUMBER OF TYPES in WHICH BRANCH:

Group by using linq (range + count)

var data = new[] {
new { Id = 0, Cat = 1, Price = 2 },
new { Id = 1, Cat = 1, Price = 10 },
new { Id = 2, Cat = 1, Price = 30 },
new { Id = 3, Cat = 2, Price = 50 },
new { Id = 4, Cat = 2, Price = 120 },
new { Id = 5, Cat = 2, Price = 200 },
new { Id = 6, Cat = 2, Price = 1024 },
};
var ranges = new[] { 10, 50, 100, 500 };
Needed output is grouped price count by equal or greater than the range used according categories.
(in one linq statement)
cat range count
-------------------------------------
1 10 2 (In 1. categories there is 2 item that price >= 10(range) [10;30])
2 10 4 (In 2. categories there is 4 item that price >= 10(range) [50;120;200;1024])
2 50 4 ....
2 100 3 ....
2 500 1 (In 2. categories there is 1 item that price >= 500(range) [1024])

Try this:
var data = new[] {
new { Id = 0, Cat = 1, Price = 2 },
new { Id = 1, Cat = 1, Price = 10 },
new { Id = 2, Cat = 1, Price = 30 },
new { Id = 3, Cat = 2, Price = 50 },
new { Id = 4, Cat = 2, Price = 120 },
new { Id = 5, Cat = 2, Price = 200 },
new { Id = 6, Cat = 2, Price = 1024 },
};
var ranges = new[] { 10, 50, 100, 500 };
var result = from r in ranges
from g in data
where g.Price >= r
select new {g.Cat, Price=r};
var groupedData =
from d in result
group d by new{d.Cat, d.Price} into g
select new{Cat=g.Key.Cat, Price=g.Key.Price, TotalCount=g.Count()};

This should work:
var values =
data.SelectMany(x => ranges.Where(y => x.Price >= y)
.Select(y => new { Record = x, Range = y }))
.GroupBy(x => new { Cat = x.Record.Cat, Range = x.Range })
.Select(x => new { Cat = x.Key.Cat, Range = x.Key.Range, Count = x.Count()});
Results:
{ Cat = 1, Range = 10, Count = 2 }
{ Cat = 2, Range = 10, Count = 4 }
{ Cat = 2, Range = 50, Count = 4 }
{ Cat = 2, Range = 100, Count = 3 }
{ Cat = 2, Range = 500, Count = 1 }
