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();

How to get Bitcoin Private Key from an ExtPrivKey using NBitcoin

So, I am trying to send some money over using NBitcoin, there is a step where i am failing and that is creating de bitcoin secret to sign the transaction, I have the address, and the ExtPrivKey but i haven't gotten any luck signing it, any recommendation, this is my code below.
var priv = mbwallet.SelectedWallet.PrivateKeys[0].ToWif();
//var ool = new BitcoinSecret(base58, App.Network);
var privkey = mbwallet.SelectedWallet.PrivateKeys[0].PrivateKey.GetBitcoinSecret(App.Network).ToWif();
var key = Key.Parse(privkey, App.Network);
var keysT = key.GetWif(App.Network);
//var myaddress = mbwallet.SelectedWallet.PrivateKeys[0].PrivateKey.PubKey.GetAddress(App.Network);
var myaddress = mbwallet.SelectedWallet.CurrentAddress;
string address = Address.Text;
var destination = BitcoinAddress.Create(address, App.Network);
decimal value = Convert.ToDecimal(Value.Text);
var coins2 = GetCoins(value);
TransactionBuilder txBuilder = new TransactionBuilder();
var tx = txBuilder.AddCoins(coins2)
.AddKeys(keysT)
.SetChange(myaddress)
.Send(destination, new Money(value, MoneyUnit.BTC))
.SendFees("0.0002");
//.BuildTransaction(true);
var tx2 = txBuilder.BuildTransaction(true);
//Console.WriteLine(txBuilder.Verify(tx));
var hello = tx2.ToHex();
var txRepo = new NoSqlTransactionRepository();
//txRepo.Put(tx.GetHash(), tx);
//Assert(txBuilder.Verify(tx)); //check fully signed
List<ICoin> GetCoins(decimal sendAmount)
{
//var mbwallet = (root.DataContext as MainWindowViewModel);
var amountMoney = new Money(sendAmount, MoneyUnit.BTC);
var client = new QBitNinjaClient(App.Network);
var txInAmount = Money.Zero;
var coins1 = new List<ICoin>();
foreach (var balance in client.GetBalance(mbwallet.SelectedWallet.CurrentAddress,//MBWallet.Wallet.Address,
true).Result.Operations)
{
var transactionId = balance.TransactionId;
var transactionResponse =
client.GetTransaction(transactionId).Result;
var receivedCoins = transactionResponse.ReceivedCoins;
foreach (Coin coin in receivedCoins)
{
if (coin.TxOut.ScriptPubKey ==
mbwallet.SelectedWallet.CurrentAddress.ScriptPubKey)//MBWallet.Wallet.BitcoinPrivateKey.ScriptPubKey) // this may not be necessary
{
coins1.Add(coin);
txInAmount += (coin.Amount as Money);
}
}
}
return coins1;
}

For what I see in the code you already add the private key to the builder so basically you only need to sign , something like this
Transaction signed = txBuilder.SignTransaction(tx2);

how to process hits on lucene 3.03

List<SearchResults> Searchresults = new List<SearchResults>();
// Specify the location where the index files are stored
string indexFileLocation = #"D:\Lucene.Net\Data\Persons";
Lucene.Net.Store.Directory dir = FSDirectory.Open(indexFileLocation);
// specify the search fields, lucene search in multiple fields
string[] searchfields = new string[] { "FirstName", "LastName", "DesigName", "CatagoryName" };
IndexSearcher indexSearcher = new IndexSearcher(dir);
// Making a boolean query for searching and get the searched hits
Query som = QueryMaker(searchString, searchfields);
int n = 1000;
TopDocs hits = indexSearcher.Search(som,null,n);
for (int i = 0; i <hits.TotalHits; i++)
{
SearchResults result = new SearchResults();
result.FirstName = hits.ScoreDocs.GetValue(i).ToString();
result.FirstName = hits.Doc.GetField("FirstName").StringValue();
result.LastName = hits.Doc(i).GetField("LastName").StringValue();
result.DesigName = hits.Doc(i).GetField("DesigName").StringValue();
result.Addres = hits.Doc(i).GetField("Addres").StringValue();
result.CatagoryName = hits.Doc(i).GetField("CatagoryName").StringValue();
Searchresults.Add(result);
}
i have table fields first name last name .... how can i process hit to get the values from the search result
i have an error that says TopDocs does not contain defination for doc

Lean on the compiler. There is no property or method called Doc in TopDocs class. In ScoreDocs property of TopDocs class you have list of hits with document number and score. You need to use this document number to get actual document. After that use method Doc which is in IndexSearcher to query for document with this number. And then you can get stored field data from that document.
You can process results like that:
foreach (var scoreDoc in hits.ScoreDocs)
{
var result = new SearchResults();
var doc = indexSearcher.Doc(scoreDoc.Doc);
result.FirstName = doc.GetField("FirstName").StringValue;
result.LastName = doc.GetField("LastName").StringValue;
result.DesigName = doc.GetField("DesigName").StringValue;
result.Addres = doc.GetField("Addres").StringValue;
result.CategoryName = doc.GetField("CategoryName").StringValue;
Searchresults.Add(result);
}
Or in more LINQ way:
var searchResults =
indexSearcher
.Search(som, null, n)
.ScoreDocs
.Select(scoreDoc => indexSearcher.Doc(scoreDoc))
.Select(doc =>
{
var result = new SearchResults();
result.FirstName = doc.GetField("FirstName").StringValue;
result.LastName = doc.GetField("LastName").StringValue;
result.DesigName = doc.GetField("DesigName").StringValue;
result.Addres = doc.GetField("Addres").StringValue;
result.CategoryName = doc.GetField("CategoryName").StringValue;
return result;
})
.ToList();

Separation of hits method will let you clear the matched documents and in future if you want to highlight the matched documents then you can easily embed the lucene.net highlighter in getMatchedHits method.
List<SearchResults> Searchresults = new List<SearchResults>();
// Specify the location where the index files are stored
string indexFileLocation = #"D:\Lucene.Net\Data\Persons";
Lucene.Net.Store.Directory dir = FSDirectory.Open(indexFileLocation);
// specify the search fields, lucene search in multiple fields
string[] searchfields = new string[] { "FirstName", "LastName", "DesigName", "CatagoryName" };
IndexSearcher indexSearcher = new IndexSearcher(dir);
// Making a boolean query for searching and get the searched hits
Query som = QueryMaker(searchString, searchfields);
int n = 1000;
var hits = indexSearcher.Search(som,null,n).ScoreDocs;
Searchresults = getMatchedHits(hits,indexSearcher);
getMatchedHits method code:
public static List<SearchResults> getMatchedHits(ScoreDoc[] hits, IndexSearcher searcher)
{
List<SearchResults> list = new List<SearchResults>();
SearchResults obj;
try
{
for (int i = 0; i < hits.Count(); i++)
{
// get the document from index
Document doc = searcher.Doc(hits[i].Doc);
string strFirstName = doc.Get("FirstName");
string strLastName = doc.Get("LastName");
string strDesigName = doc.Get("DesigName");
string strAddres = doc.Get("Addres");
string strCategoryName = doc.Get("CategoryName");
obj = new SearchResults();
obj.FirstName = strFirstName;
obj.LastName = strLastName;
obj.DesigName= strDesigName;
obj.Addres = strAddres;
obj.CategoryName = strCategoryName;
list.Add(obj);
}
return list;
}
catch (Exception ex)
{
return null; // or throw exception
}
}
Hope it Helps!

Trouble Fetching Value in Variable

Basically here's my code which I'm having trouble with. Insanely new to mongoDB and would love to understand how to get values out of a JSON string that is returns in the variable 'line'.
public string get_data()
{
var client = new MongoClient();
var db = client.GetDatabase("test");
var collection = db.GetCollection<BsonDocument>("metacorp");
var cursor = collection.Find("{'movie_name' : 'Hemin'}").ToCursor();
var line = "";
foreach (var document in cursor.ToEnumerable())
{
using (var stringWriter = new StringWriter())
using (var jsonWriter = new JsonWriter(stringWriter))
{
var context = BsonSerializationContext.CreateRoot(jsonWriter);
collection.DocumentSerializer.Serialize(context, document);
line = stringWriter.ToString();
}
}
var js = new JavaScriptSerializer();
var d = js.Deserialize<dynamic>(line);
var a = d["movie_name"];
return line;
}
This is the output I get if I return line:
{ "_id" : ObjectId("58746dcafead398e4d7233f5"), "movie_name" : "Hemin"
}
I want to be able to fetch the value 'Hemin' into 'a'.

I know this is not what you're asking for but since you're using the c# driver then I would recommend the following. Assumes you have a c# class corresponding to metacorp collection or at least a serializer that handles it. Hope it helps.
var client = new MongoClient();
var db = client.GetDatabase("test");
var collection = db.GetCollection<MetaCorp>("metacorp");
var m = collection.SingleOrDefault(x => x.Movie_Name == "Hemin"); // Assuming 0 or 1 with that name. Use Where otherwise
var movieName = "Not found";
if(m!= null)
movieName = m.Movie_Name;

You could have your dto class for movie ans just fetch the data from collection:
public class Movie
{
public ObjectId Id { get; set; }
public string movie_name { get; set;}
}
...
var client = new MongoClient();
var db = client.GetDatabase("test");
var collection = db.GetCollection<BsonDocument>("metacorp");
var movies = collection.Find(x=>x.movie_name == "Hemin").ToEnumerable();

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
