add two group into one group in c#

I have two groups like below, theyh have different data. Based on both I need to create an xml file .
How can I write a for-loop for both groups and generate a single xml file?
var groups = checkFile.AsEnumerable().GroupBy(x => new { DocNum = x.Field<int>("orderid"), Type = x.Field<string>("Type"), ProdName = x.Field<string>("ProdName"), Status = x.Field<string>("Status"), productno = x.Field<string>("productno"), uom = x.Field<string>("uom"), customer = x.Field<string>("customer"), remark = x.Field<string>("remark"), U_JobNumber = x.Field<string>("U_JobNumber"), U_SalesPerson = x.Field<string>("U_SalesPerson"), U_POnum = x.Field<string>("U_POnum"), U_JobType = x.Field<string>("U_JobType"), PlannedQty = x.Field<decimal>("PlannedQty"), OriginNum = x.Field<int?>("OriginNum"), orderdate = x.Field<DateTime>("orderdate"), duedate = x.Field<DateTime>("duedate"), DocTotal = x.Field<decimal>("DocTotal") });
var groups2 = checkFile2.AsEnumerable().GroupBy(x => new { DocNum = x.Field<int>("DocNum") });
//now i need to take both group data inside this loop to print the file
foreach (var group in groups)
{
var stringwriter = new StringWriter();
using (var xmlWriter = XmlWriter.Create(stringwriter, new XmlWriterSettings { Indent = true }))
{
xmlWriter.WriteStartDocument();
xmlWriter.WriteStartElement("Root");
xmlWriter.WriteEndElement();
}
var xml = stringwriter.ToString();
XmlDocument docSave = new XmlDocument();
docSave.LoadXml(stringwriter.ToString());
docSave.Save(System.IO.Path.Combine(#SystemSettings.ImportBankStatementPendingFolderPath, "DocNum -" + group.Key.DocNum + ".xml"));
count++;
}

Try following :
DataTable checkFile = new DataTable();
var groups = checkFile.AsEnumerable().GroupBy(x => new
{
DocNum = x.Field<int>("orderid"),
Type = x.Field<string>("Type"),
ProdName = x.Field<string>("ProdName"),
Status = x.Field<string>("Status"),
productno = x.Field<string>("productno"),
uom = x.Field<string>("uom"),
customer = x.Field<string>("customer"),
remark = x.Field<string>("remark"),
U_JobNumber = x.Field<string>("U_JobNumber"),
U_SalesPerson = x.Field<string>("U_SalesPerson"),
U_POnum = x.Field<string>("U_POnum"),
U_JobType = x.Field<string>("U_JobType"),
PlannedQty = x.Field<decimal>("PlannedQty"),
OriginNum = x.Field<int?>("OriginNum"),
orderdate = x.Field<DateTime>("orderdate"),
duedate = x.Field<DateTime>("duedate"),
DocTotal = x.Field<decimal>("DocTotal")
});
DataTable checkFile2 = new DataTable();
//now i need to take both group data inside this loop to print the file
foreach (var group in groups)
{
List<DataRow> groups2 = checkFile2.AsEnumerable().Where(x => group.Key.DocNum == x.Field<int>("DocNum")).ToList();
}

IList<T> return as a generic

I'm a beginner for coding ,and I was trying to create a search engine , but there s a part I dont know how to solve it that returns an IList as a generic,
public IList<T> Search<T>(string textSearch)
{
IList<T> list = new List<T>();
var result = new DataTable();
using (Analyzer analyzer = new PanGuAnalyzer())
{
var queryParser = new QueryParser(Version.LUCENE_30, "FullText", analyzer);
queryParser.AllowLeadingWildcard = true;
var query = queryParser.Parse(textSearch);
var collector = TopScoreDocCollector.Create(1000, true);
Searcher.Search(query, collector);
var matches = collector.TopDocs().ScoreDocs;
result.Columns.Add("Title");
result.Columns.Add("Starring");
result.Columns.Add("ID");
foreach (var item in matches)
{
var id = item.Doc;
var doc = Searcher.Doc(id);
var row = result.NewRow();
row["Title"] = doc.GetField("Title").StringValue;
row["Starring"] = doc.GetField("Starring").StringValue;
row["ID"] = doc.GetField("ID").StringValue;
result.Rows.Add(row);
}
}
return result;
}
but in this code , I couldn't return result ,it says Cannot Implicitly convert type 'Data.DataTable' to 'Generic.IList',An explicit conversion exists.so how can I solve this?

I guess you don't want to support generics since it doesn't make sense and is impossible. You have a class, for example Film, then return a List<Film>, you don't need the DataTable:
public IList<Film> SearchFilms(string textSearch)
{
IList<Film> list = new List<Film>();
using (Analyzer analyzer = new PanGuAnalyzer())
{
var queryParser = new QueryParser(Version.LUCENE_30, "FullText", analyzer);
queryParser.AllowLeadingWildcard = true;
var query = queryParser.Parse(textSearch);
var collector = TopScoreDocCollector.Create(1000, true);
Searcher.Search(query, collector);
var matches = collector.TopDocs().ScoreDocs;
foreach (var item in matches)
{
var film = new Film();
var id = item.Doc;
var doc = Searcher.Doc(id);
film.Title = doc.GetField("Title").StringValue;
film.Starring = doc.GetField("Starring").StringValue;
film.ID = doc.GetField("ID").StringValue;
list.Add(film);
}
}
return list;
}

Your return statement should be
result.AsEnumerable().ToList();
Don't forget to add namespace
using System.Linq;

How to add/update milestones in a feature using rally rest API and C#?

I am not able to add or update milestones field for the Features in the Rally. If anyone having the code available using C# to update the same, please share with me. I am searching and doing from last one week with no luck.
When I am trying to add/Update milestones in the Features. I am getting the error as "Could not read: Could not read referenced object null". My code is as follows:-
public DynamicJsonObject UpdateFeaturesbyName(string fea, string bFun)
{
//getting list of Feature.
Request feat = new Request("PortfolioItem/Feature");
feat.Query = new Query("Name", Query.Operator.Equals, fea);
QueryResult TCSResults = restApi.Query(feat);
foreach (var res in TCSResults.Results)
{
var steps = res["Milestones"];
Request tsteps = new Request(steps);
QueryResult tstepsResults = restApi.Query(tsteps);
foreach (var item in tstepsResults.Results)
{
}
if (res.Name == fea)
{
var targetFeature = TCSResults.Results.FirstOrDefault();
DynamicJsonObject toUpdate = new DynamicJsonObject();
//toUpdate["Milestones"] = "";
// CreateResult createResult = restApi.Create(steps._ref, toUpdate);
// String contentRef = steps._ref;
//String contentRef = createResult._ref;
string[] value = null;
string AccCri = string.Empty;
if (!string.IsNullOrWhiteSpace(bFun))
{
value = bFun.Split(new string[] { "\r\n", "\n" }, StringSplitOptions.None);
foreach (string item in value)
{
//if (string.IsNullOrWhiteSpace(AccCri))
// AccCri = item;
//else
// AccCri = AccCri + "<br/>" + item;
if (!string.IsNullOrWhiteSpace(item))
{
//Query for Milestone.
Request ms = new Request("Milestone");
ms.Fetch = new List<string>() { "Name", "ObjectID" };
ms.Query = new Query("Name", Query.Operator.Equals, item);
QueryResult msResults = restApi.Query(ms);
var targetMLResult = msResults.Results.FirstOrDefault();
long MLOID = targetMLResult["ObjectID"];
DynamicJsonObject tarML = restApi.GetByReference("Milestone", MLOID, "Name", "_ref", "DisplayColor");
DynamicJsonObject targetML = new DynamicJsonObject();
targetML["Name"] = tarML["Name"];
//targetML["_ref"] = tarML["_ref"];
targetML["_ref"] = "/milestone/" + Convert.ToString(MLOID);
targetML["DisplayColor"] = tarML["DisplayColor"];
// Grab collection of existing Milestones.
var existingMilestones = targetFeature["Milestones"];
long targetOID = targetFeature["ObjectID"];
// Milestones collection on object is expected to be a System.Collections.ArrayList.
var targetMLArray = existingMilestones;
var tagList2 = targetMLArray["_tagsNameArray"];
tagList2.Add(targetML);//
//targetMLArray.Add(targetML);
targetMLArray["_tagsNameArray"] = tagList2;
toUpdate["Milestones"] = targetMLArray;
OperationResult updateResult = restApi.Update(res._ref, toUpdate);
bool resp = updateResult.Success;
}
}
}
//toUpdate["c_AcceptanceCriteria"] = AccCri;
//OperationResult updateResult = restApi.Update(res._ref, toUpdate);
}
}
var features = TCSResults.Results.Where(p => p.Name == fea).FirstOrDefault();
var featuresref = features._ref;
return features;
}

Now that v3.1.1 of the toolkit has been released you can use the AddToCollection method to do this.
Otherwise, you can still always just update the full collection. The value should be an arraylist of objects with _ref properties.
Check out this example (which adds tasks to defects, but should be very similar to what you're doing): https://github.com/RallyCommunity/rally-dot-net-rest-apps/blob/master/UpdateTaskCollectionOnDefect/addTaskOnDefect.cs

Field Boosting Doesn't Work/Effect Lucene.net

I'm trying to set boosting on documents fields to make the search results more accurate but as i see it doesn't work
however
here is my code
Indexing:
private static void _addToLuceneIndex(Datafile Datafile, IndexWriter writer)
{
// remove older index entry
var searchQuery = new TermQuery(new Term("Id", Datafile.article.Id.ToString()));
writer.DeleteDocuments(searchQuery);
// add new index entry
var doc = new Document();
var id = new Field("Id", Datafile.article.Id.ToString(), Field.Store.YES, Field.Index.NOT_ANALYZED);
var content = new Field("Content", Datafile.article.Content, Field.Store.YES, Field.Index.ANALYZED, Field.TermVector.WITH_POSITIONS);
content.Boost = 4;
var title = new Field("Title", Datafile.article.Title, Field.Store.YES, Field.Index.ANALYZED);
title.Boost = 6;
doc.Add(id);
doc.Add(content);
doc.Add(title);
foreach (var item in Datafile.article.Article_Tag)
{
var tmpta = new Field("Atid", item.Id.ToString(), Field.Store.YES, Field.Index.NOT_ANALYZED);
var tagname = new Field("Tagname", item.Tag.name, Field.Store.YES, Field.Index.ANALYZED);
tagname.Boost = 8;
doc.Add(tmpta);
doc.Add(tagname);
}
// add lucene fields mapped to db fields
// add entry to index
writer.AddDocument(doc);
}
i've used Lukenet to see if the fields boosted however it doesn't and boosting still equal to 1.0
so i tried to run and test it ,but the result disappoint me anyway
here is my search code:
searching:
private static IEnumerable<Datafile> _search(string searchQuery, string searchField = "")
{
// validation
if (string.IsNullOrEmpty(searchQuery.Replace("*", "").Replace("?", "")))
return new List<Datafile>();
var indexReader = IndexReader.Open(Directory, false);
// set up lucene searcher
using (var searcher = new IndexSearcher(indexReader))
{
var hits_limit = 1000;
// search by single field
var enanalyzer = new SnowballAnalyzer(Version.LUCENE_30, "English");
var aranalyzer = new SnowballAnalyzer(Version.LUCENE_30, "Arabic");
string[] fields = new string[] { "Title", "Content", "Tagname" };
// Dictionary<string, float> boosts = new Dictionary<string, float>();
// boosts.Add("Title", 5);
// boosts.Add("Content", 3);
// boosts.Add("Tagname", 7);
var enparser = new MultiFieldQueryParser(Version.LUCENE_30, fields, enanalyzer);
var arparser = new MultiFieldQueryParser(Version.LUCENE_30, fields, aranalyzer);
var query = QueryModel(searchQuery, new QueryParser[] { enparser, arparser });
searcher.SetDefaultFieldSortScoring(true, false);
TopFieldCollector collector = TopFieldCollector.Create(new Sort(new SortField(null, SortField.SCORE, false), new SortField("Title", SortField.STRING, true), new SortField("Tagname", SortField.STRING, true), new SortField("Content", SortField.STRING, true)),
hits_limit,
false, // fillFields - not needed, we want score and doc only
true, // trackDocScores - need doc and score fields
true, // trackMaxScore - related to trackDocScores
false); // should docs be in docId order?
searcher.Search(query, collector);
var hits = collector.TopDocs().ScoreDocs;
var results = new List<Datafile>();
foreach (var hit in hits)
{
var doc = searcher.Doc(hit.Doc);
var df = _mapLuceneDocumentToData(doc);
df.score = hit.Score;
results.Add(df);
}
searcher.Dispose();
return results;
// search by multiple fields (ordered by RELEVANCE)
}
}
QueryModel Method:
private static Query QueryModel(string searchQuery, QueryParser[] parsers)
{
BooleanQuery query = new BooleanQuery();
searchQuery = "*" + searchQuery + "*";
foreach (var parser in parsers)
{
parser.AllowLeadingWildcard = true;
var thequery = parser.Parse(searchQuery);
query.Add(new BooleanClause(thequery, Occur.SHOULD));
}
return query;
}
i'm new with lucene.net i love it but i can't get my head around this problem
PS:
also i want to get a fuzzy query as like when the user enter :
city in russua to get a result as if he enter: city in russia
i tried FuzzyQuery Class But it doesn't work anyway ,and is it necessary to use FuzzyQuery Class or not to get that result

So Since no one answer my question and i have found a solution for this issue i've used a search time query boosting and here is my code:
var QParser = new QueryParser(Version.LUCENE_30, "Content", analyzer);
QParser.AllowLeadingWildcard = true;
var Query = new QParser.Parse(searchQuery);
Query.Boost = 7.0f;
return Query;
you can use BooleanQuery if you want to Do an Or,And search

Nested XML from list with needed data on multiple lines

I need to format an XML to a given hierarchy from a list (List<>). The list contains, for the banking information, data spread across multiple rows as shown in the image.
The XML output needs to be formatted like this:
<ROOT>
<DocumentElement>
<Supplier>
<Company>STV</Company>
<Code>000199</Code>
<Name>TrafTrans</Name>
<BankAccounts>
<SupplierBankAccount>
<Bban>220-012510-63</Bban>
<Name>B1</Name>
</SupplierBankAccount>
<SupplierBankAccount>
<Bban>RUIL</Bban>
<Name>RUIL</Name>
</SupplierBankAccount>
</BankAccounts>
<SupplierAddresses>
<SupplierAddress>
<Type>PostalAddress</Type>
<Name>Loc TrafTrans</Name>
<IsDefault>true</IsDefault>
<AddressParts>
<SupplierAddressPart>
<AddressPartKey>STREET_NAME</AddressPartKey>
<AddressPartText>Somewhere</AddressPartText>
</SupplierAddressPart>
<SupplierAddressPart>
<AddressPartKey>COUNTRY</AddressPartKey>
<AddressPartText>SPAIN</AddressPartText>
</SupplierAddressPart>
</AddressParts>
</SupplierAddress>
</SupplierAddresses>
</Supplier>
</DocumentElement>
</ROOT>
I already have a method that converts a list to an XML and returns a string. But the problem is that this only formats one item from the list and there could be additional info in the following items.
public static string SuppliersToXML(List<SupplierItem> supplier)
{
CultureInfo ci = new CultureInfo("en-US");
XmlDocument doc = new XmlDocument();
var root = doc.CreateElement("ROOT");
var rootNode = doc.AppendChild(root);
var docElem = doc.CreateElement("DocumentElement");
var docElemNode = rootNode.AppendChild(docElem);
foreach (var item in supplier)
{
var supplierElem = doc.CreateElement("Supplier");
var companyElem = (XmlNode)doc.CreateElement("Company");
companyElem.InnerText = item.Company.ToString();
//more code...
supplierElem.AppendChild(companyElem);
//more code...
}
return doc.OuterXml;
}

I have found the answer myself, it may not be the prettiest code ever written. But it does the job.
public static string SuppliersToXML(List<SupplierItem> supplier)
{
//A distinct select is needed because bank info can be on multiple lines. So first a list is generated with correct info except for bank information
List<SupplierItem> distinctsupplier = supplier
.GroupBy(p => p.Code)
.Select(g => g.First())
.ToList();
CultureInfo ci = new CultureInfo("en-US");
XmlDocument doc = new XmlDocument();
var root = doc.CreateElement("ROOT");
var rootNode = doc.AppendChild(root);
var docElem = doc.CreateElement("DocumentElement");
var docElemNode = rootNode.AppendChild(docElem);
foreach (var item in distinctsupplier)
