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();

var orderJson = JsonConvert.DeserializeObject<dynamic>(httpResultStr);
var orderidCount = orderJson.data.orderUuids.Count;
for (int i = 0; i <= orderidCount; i++)
{
var orderId = orderJson.data.orderUuids[i]; // my fail attempt. Didnt work
var map = orderJson.data.ordersMap;
foreach (var d in map)
{
var receipt = d.fareInfo.totalPrice;
Console.WriteLine(receipt);
}
}
Im trying to access the ordersMap members with the given values in orderUuids object. Inside the ordersMap Ids contain the fareInfo.totalPrice property that I'm trying to access. How would I go about achieving this?
[![json tree with ordersMap. Trying to access its members with the given values in orderUuids object.][1]][1]
You can make a partial/full map using the JSON file and use JsonConvert.DeserializeObject<>(json).
Other solution could be create a partial map using an anonymous type. Here is a code snip.
var anonymousTypeObject = new
{
status = "",
data = new
{
ordersMap = new Dictionary<string, JToken>(),
orderUuids = new string[0]
}
};
var obj = JsonConvert.DeserializeAnonymousType(json, anonymousTypeObject);
foreach (var kvp in obj.data.ordersMap)
{
var totalPrice = kvp.Value["fareInfo"]?["totalPrice"]?.ToString();
Debug.WriteLine($"{kvp.Key} -> {totalPrice}");
}
EDIT If you don't want any map use this solution.
var jObj = JsonConvert.DeserializeObject<JObject>(json);
var orderUuids = jObj.SelectToken("data.orderUuids")?.Values<string>();
foreach (var orderUuid in orderUuids)
{
var totalPrice = jObj.SelectToken($"data.ordersMap.{orderUuid}.fareInfo.totalPrice")?.Value<double>();
Debug.WriteLine($"{orderUuid} -> {totalPrice}");
}
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);
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);//

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
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

It seems I don't understand how I can get a value from a collection inside a document. I am using mongoDB in C#.
Here is my code:
var jimi = new Document();
jimi["Firstname"] = "Jimi";
jimi["Lastname"] = "James";
jimi["Pets"] = new[]
{
new Document().Append("Type", "Cat").Append("Name", "Fluffy"),
new Document().Append("Type", "Dog").Append("Name", "Barky"),
new Document().Append("Type", "Gorilla").Append("Name", "Bananas"),
};
test.Insert(jimi);
var query = new Document().Append("Pets.Type","Cat");
So my query will look for the pet cat. But I am not sure how I can get the name of my cat. I tried a few things but I mostly get the whole document back.
Thanks in advance,
Pickels
This isn't as elegant as I'd like as I'm still learning about MongoDB myself but it does show you one way to get the property you wanted.
