please tell me, how do I get the json like this:
dynamic packet = new ExpandoObject();
packet.type = "somethink";
packet.user = 12345;
packet.nets[0].amout = 123;
packet.nets[0].lower = 0;
packet.nets[1].amout = 345;
packet.nets[1].lower = 1;
string input = Newtonsoft.Json.JsonConvert.SerializeObject(packet);
Its not workig, error:
An unhandled exception of type "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" in System.Core.dll
For more information: "System.Dynamic.ExpandoObject" does not contain definitions of "nets"
Thanks.
It's the ExpandoObject who's a dynamic object. The rest of properties should be other ExpandoObject instances or regular objects, arrays, collections...
For example:
packet.nets = new[]
{
new { amount = 123, lower = 0 },
new { amount = 345, lower = 1 }
}
Or:
packet.nets = new[]
{
new Dictionary<string, int> { { "amount", 345 }, { "lower", 0 } },
new Dictionary<string, int> { { "amount", 123 }, { "lower", 1 } }
}
There're many other approaches, including the use of instances of concrete classes.
Firstly, you need create nets in packet object, like this:
packet.nets = new dynamic[2];
And initialize the objects in nets, if you want with `ExpandoObject too:
packet.nets[0] = new ExpandoObject();
packet.nets[1] = new ExpandoObject();
Then is done, complete code:
dynamic packet = new ExpandoObject();
packet.type = "somethink";
packet.user = 12345;
packet.nets = new dynamic[2];
packet.nets[0] = new ExpandoObject();
packet.nets[0].amout = 123;
packet.nets[0].lower = 0;
packet.nets[1] = new ExpandoObject();
packet.nets[1].amout = 345;
packet.nets[1].lower = 1;
string input = Newtonsoft.Json.JsonConvert.SerializeObject(packet);
You first need to declare nets. For example
packet.nets = new Dictionary<int, dynamic>();
Then you'll need to instantiate the instances of nets
packet.nets[0] = new {amount = 123, lower = 0};
The result being
dynamic packet = new ExpandoObject();
packet.type = "somethink";
packet.user = 12345;
packet.nets = new Dictionary<int, dynamic>();
packet.nets[0] = new { amount = 123, lower = 0 };
packet.nets[1] = new { amount = 345, lower = 1 };

I have a function in which i am getting data(array of objects) from db and then adding those objects of array one by one into a lit of type ExpandoObject
public async Task<List<ExpandoObject>> GetGroupWithMaxTickets(){
List<ExpandoObject> topGroupsWithMaxTickets = new List<ExpandoObject>();
dynamic ticketDetails = new ExpandoObject();
var pipeline_tickets = new BsonDocument[]{
new BsonDocument("$match",
new BsonDocument
{
{ "nsp", "/sbtjapan.com" },
{ "datetime",
new BsonDocument
{
{ "$gte", "2019-12-03T00:00:34.417Z" },
{ "$lte", "2019-12-03T24:00:34.417Z" }
} }
}),
new BsonDocument("$group",
new BsonDocument
{
{ "_id", "$group" },
{ "totalTIckets",
new BsonDocument("$sum", 1) }
}),
new BsonDocument("$project",
new BsonDocument
{
{ "_id", 0 },
{ "group", "$_id" },
{ "totalTIckets", 1 }
}),
new BsonDocument("$sort",
new BsonDocument("totalTIckets", -1)),
new BsonDocument("$limit", 5)
};
var collection = await DbService.tickets.AggregateAsync<RawBsonDocument>(pipeline_tickets, new AggregateOptions {UseCursor = true, BatchSize = 500});
await collection.MoveNextAsync();
if(collection.Current.ToList().Count > 0){
// ticketDetails = JsonConvert.DeserializeObject(collection.Current.ToJson());
// ticketDetails.group = collection.Current.ToList()[0]["group"];
// ticketDetails.totalTickets = collection.Current.ToList()[0]["totalTIckets"];
Parallel.ForEach(collection.Current.ToList(), (ticket) => {
Console.WriteLine("Ticket----"+ticket);
dynamic groupWithTickets = new ExpandoObject();
groupWithTickets = ticket;
topGroupsWithMaxTickets.Add(groupWithTickets);
});
}
return topGroupsWithMaxTickets;
}
But it throws an error like this
System.AggregateException: One or more errors occurred. (The best overloaded method match for 'System.Collections.Generic.List<System.Dynamic.ExpandoObject>.Add(System.Dynamic.ExpandoObject)' has some invalid arguments)
I want that my function must return array of objects of type List<ExpandoObject>
How can i do this in c#?
Since you have changed the question, following is the answer that should resolve your matters.
How to NOT work with ExpandoObjects
I tested this on my system and got it to reproduce the same results as you are getting. Following is the failed try:
dynamic employee = new ExpandoObject();
List<ExpandoObject> listOfEmployees = new List<ExpandoObject>();
employee = "someStrangeString";
listOfEmployees.Add(employee); // ERROR !!!!
and just as expected, i get the following error on Add.
Microsoft.CSharp.RuntimeBinder.RuntimeBinderException
HResult=0x80131500
Message=The best overloaded method match for 'System.Collections.Generic.List.Add(System.Dynamic.ExpandoObject)' has some invalid arguments
Source=
StackTrace:
Corrected way of ExpandoObject use
Following is the method that will take care of the issues with Adding it to the list.
Parallel.ForEach(collection.Current.ToList(), (ticket) =>
{
Console.WriteLine("Ticket----" + ticket);
dynamic groupWithTickets = new ExpandoObject();
groupWithTickets.users = ticket; //<---- Assign ticket to users element.
topGroupsWithMaxTickets.Add(groupWithTickets);
});
What was done to fix it?
When you are working with ExpandoObjects, you have to think of dictionary type of a deal. When you declare ExpandoObject, you have to dynamically assign the value to an element (that you define).
Example from MS site: shows the proper use of ExpandoObject
dynamic employee, manager;
employee = new ExpandoObject();
employee.Name = "John Smith";
employee.Age = 33;
manager = new ExpandoObject();
manager.Name = "Allison Brown";
manager.Age = 42;
manager.TeamSize = 10;
Hopefully this resolves your issue.
It should be like this;
dynamic ticketDetails = new ExpandoObject();
ticketDetails.user = collection;
string json = Newtonsoft.Json.JsonConvert.SerializeObject(ticketDetails);
You can simply do this:
dynamic ticketDetails = new ExpandoObject();
ticketDetails = Json(new users = JsonConvert.DeserializeObject(collection.Current.ToJson()));
For testing purposes, i used an array arr that holds one of the elements. If you need that array to be part of ExtendoObject with first element being users, you can create a Json object and set the array as value to the "users" element.
dynamic ticketDetails = new ExpandoObject();
JArray arr = new JArray();
arr.Add(#"[{""name"": ""Alex"", ""age"": 21}]");
JObject o = new JObject();
o["users"] = arr.ToString();
ticketDetails = o;
// output: { "users" : [{"name" : "Alex", "age" : 21}]}
I am web-scraping some data and trying to write the scraped data to a json file using C# newtonsoft.Json
I get stuck when writing a foreach in my .ToDictionary function as well as not being able to ++ an index into my .ToDictionary function.
My class:
public class JsonParametersData
{
public bool required { get; set; }
public bool list { get; set; }
public List<string> options { get; set; }
}
My arrays
var jsonData = new List<Dictionary<string, Dictionary<string, JsonParametersData>>>();
var moduleParameters = new List<string>();
var parameterOptionsArray = new List<List<string>>();
var parameterOptions = new List<string>();
var requiredArray = new List<bool>();
var listArray = new List<bool>();
string moduleName = item.Attributes["href"].Value.Replace("_module.html", "");
The code which is commented shows what I am trying to do.
int index = 0;
jsonData.Add(new Dictionary<string, Dictionary<string, JsonParametersData>>()
{
{
moduleName,
moduleParameters
.ToDictionary(n => n,
n => new JsonParametersData
{
required = requiredArray[index],
list = listArray[index],
options = new List<string>() { "option1", "option2" },
/*
foreach (var parameteroption in parameterOptionsArray[index])
{
options.Add(parameteroption);
}
index++;
*/
})
}
});
string json = JsonConvert.SerializeObject(jsonData.ToArray());
//write string to file
System.IO.File.WriteAllText(#"path", json);
Your parameterOptionsArray is not an Array, but a List of lists.
The thing is that parameterOptionsArray[index] is a List, not a string. So you should use AddRange() instead of Add().
parameterOptionsArray.Foreach(parameteroption => options.AddRange(parameteroption));
As I´ve written in the comments you can make only assignments in an object-initializer. Thus the following is allowed:
var a = new { MyMember = anInstance }
whilst this is not:
var a = new { MyMember = anInstance, anInstance.DoSomething() };
That´s one of those cases where you should not use Linq at all, as it leads to more confusion than it helps. Instead use a good old-styled loop:
int index = 0;
var innerDict = new Dictionary<string, JsonParametersData>();
foreach(var name in moduleParameters)
{
innerDict[name] = new JsonParametersData
{
required = requiredArray[index],
list = listArray[index],
options = new List<string>() { "option1", "option2" },
}
innerDict[name].Options.AddRange(parameterOptionsArray[index]);
index++;
}
var dict = new Dictionary<string, Dictionary<string, JsonParametersData>>();
dict[moduleName] = innerDict;
jsonData.Add(dict);
string json = JsonConvert.SerializeObject(jsonData.ToArray());
You appear to have a jagged array in parameterOptionsArray. You can make use of SelectMany here. Perhaps following sample can help:
string[][] parameterOptionsArray = new string[2][];
parameterOptionsArray[0] = new string[2];
parameterOptionsArray[0][0] = "1";
parameterOptionsArray[0][1] = "2";
parameterOptionsArray[1] = new string[2];
parameterOptionsArray[1][0] = "3";
parameterOptionsArray[1][1] = "4";
var testing = new {options = parameterOptionsArray.SelectMany(x => x).ToList()};
testing.options.ForEach(x => Console.WriteLine(x));
Below is the code I'm working with to pass multiple line items to create sales order through GP Web service. I can pass single Line Item without any problem , but when I pass multiple Items it is only taking the last one. The array has around 5 Item ID and I'm passing fixed Quantity as 15, Need to make both dynamic. But for the testing purpose I'm trying like this. I know the problem with the creation/initialization of some web service objects. As novice to the entire set of things I couldn't find the exact problem.
C# Code
CompanyKey companyKey;
Context context;
SalesOrder salesOrder;
SalesDocumentTypeKey salesOrderType;
CustomerKey customerKey;
BatchKey batchKey;
// SalesOrderLine salesOrderLine;
ItemKey orderedItem;
Quantity orderedAmount;
Policy salesOrderCreatePolicy;
DynamicsGPClient wsDynamicsGP = new DynamicsGPClient();
wsDynamicsGP.ClientCredentials.Windows.ClientCredential.UserName = "Admin";
wsDynamicsGP.ClientCredentials.Windows.ClientCredential.Password = "pass";
wsDynamicsGP.ClientCredentials.Windows.ClientCredential.Domain = "Gp";
System.ServiceModel.WSHttpBinding binding;
binding = new System.ServiceModel.WSHttpBinding(System.ServiceModel.SecurityMode.None);
context = new Context();
companyKey = new CompanyKey();
companyKey.Id = (1);
context.OrganizationKey = (OrganizationKey)companyKey;
salesOrder = new SalesOrder();
salesOrderType = new SalesDocumentTypeKey();
salesOrderType.Type = SalesDocumentType.Order;
salesOrder.DocumentTypeKey = salesOrderType;
customerKey = new CustomerKey();
customerKey.Id = "121001";
salesOrder.CustomerKey = customerKey;
batchKey = new BatchKey();
batchKey.Id = "RMS";
salesOrder.BatchKey = batchKey;
// SalesOrderLine[] orders = new SalesOrderLine[6];
SalesOrderLine[] lines = { };
for (int i = 1; i < 5; i++)
{
SalesOrderLine salesOrderLine = new SalesOrderLine();
orderedItem = new ItemKey();
orderedItem.Id = Arr[i].ToString();
salesOrderLine.ItemKey = orderedItem;
orderedAmount = new Quantity();
orderedAmount.Value = 15;
salesOrderLine.Quantity = orderedAmount;
lines = new SalesOrderLine[] { salesOrderLine };
MessageBox.Show(lines.Count().ToString());
}
salesOrder.Lines = lines;
//salesOrder.Lines = orders;
salesOrderCreatePolicy = wsDynamicsGP.GetPolicyByOperation("CreateSalesOrder", context);
wsDynamicsGP.CreateSalesOrder(salesOrder, context, salesOrderCreatePolicy);
if (wsDynamicsGP.State != CommunicationState.Faulted)
{
wsDynamicsGP.Close();
}
MessageBox.Show("Success");
lines = new SalesOrderLine[] { salesOrderLine }; will recreate the lines array object each time meaning you loose any previously added objects. Effectively only the final object in the loop is actually added.
Try using a List<T> like so:
SalesOrderLine[] lines = { }; Becomes List<SalesOrderLine> lines = new List<SalesOrderLine>();
lines = new SalesOrderLine[] { salesOrderLine }; Becomes: lines.Add(salesOrderLine);
If its important you end up with an array as the input:
salesOrder.Lines = lines; Becomes: salesOrder.Lines = lines.ToArray();
I am trying to set the value of object property which is of type List and initialise it by using a foreach to add the items to the list e.g.
var sessionPlanner = new SessionPlannerDTO()
{
Age = "",
NumberOfPlayers = session.numberOfPlayers.Value,
MedicalInformation = "",
PlayerNeeds = "",
SessionDate = session.daySessionDate.Value,
Location = session.Location.locationName,
PracticeView = new List<PracticeViewDTO>(foreach(var practice in session.Sessions){
new PracticeViewDTO(){AbilityLevel = practice.ActivityPlan.abilityLevel.Value,
ActivityUrl = practice.ActivityPlan.activityUrl,
EquipmentNeeds = practice.ActivityPlan.equipmentNeeds,
FacilityNeeds = practice.ActivityPlan.activityNeeds,
HealthAndSafety = practice.ActivityPlan.healthAndSafetyIssues,
SessionTitle = practice.ActivityPlan.activityName
};
})
};
PracticeView is what I am trying to achieve by making it a list without doing the below:
var practiceViewList = new List<PracticeViewDTO>();
foreach(var practice in session.Sessions)
{
var practiceX = new PracticeViewDTO()
{
AbilityLevel = practice.ActivityPlan.abilityLevel.Value,
ActivityUrl = practice.ActivityPlan.activityUrl
};
practiceViewList.Add(practiceX);
}
You can't use other code than assignments in object or collection initializers. So your foreach() there won't compile.
Use session.Sessions.Select() to map the source entities to your DTO, and ToList() to create a list of the result:
sessionPlanner = new SessionPlannerDTO
{
Age = "",
// ...
PracticeView = session.Sessions.Select(s =>
new PracticeViewDTO
{
AbilityLevel = s.ActivityPlan.abilityLevel.Value,
// ...
}).ToList()
};
You also may want to consider using AutoMapper, instead of hand-writing mapping code.

I found the answer on my own after a long search about date format.
The restrictions has to be defined as this:
// greater or equal to
string dateStart = DateTime.Today.add(-6d);
string dateEnd = DateTime.Today.Add(1d);
PathToUnindexedFieldType dateSentPath = new PathToUnindexedFieldType();
dateSentPath.FieldURI = UnindexedFieldURIType.itemDateTimeSent;
IsGreaterThanOrEqualToType IsGreaterThanOrEqual = new IsGreaterThanOrEqualToType();
IsGreaterThanOrEqual.Item = dateSentPath;
FieldURIOrConstantType dateConstant = new FieldURIOrConstantType();
ConstantValueType dateConstantValue = new ConstantValueType();
dateConstantValue.Value = string.Format("{0}-{1}-{2}T00:00:00Z", dateStart.Year.ToString(), dateStart.Month.ToString(), dateStart.Day.ToString());
dateConstant.Item = dateConstantValue;
IsGreaterThanOrEqual.FieldURIOrConstant = dateConstant;
// less than or equal to
PathToUnindexedFieldType dateSentPath1 = new PathToUnindexedFieldType();
dateSentPath1.FieldURI = UnindexedFieldURIType.itemDateTimeSent;
IsLessThanOrEqualToType lessThanOrEqualTo = new IsLessThanOrEqualToType();
lessThanOrEqualTo.Item = dateSentPath1;
FieldURIOrConstantType dateConstant1 = new FieldURIOrConstantType();
ConstantValueType dateConstantValue1 = new ConstantValueType();
dateConstantValue1.Value = string.Format("{0}-{1}-{2}T00:00:00Z", dateEnd.Year.ToString(), dateEnd.Month.ToString(), dateEnd.Day.ToString());
dateConstant1.Item = dateConstantValue1;
lessThanOrEqualTo.FieldURIOrConstant = dateConstant1;
RestrictionType restriction = new RestrictionType();
AndType andType = new AndType();
andType.Items = new SearchExpressionType[] { lessThanOrEqualTo, IsGreaterThanOrEqual };
restriction.Item = andType;
findItemRequest.Restriction = restriction;
Hope this help someone some day ;-)
In case anyone stumbles upon this in the future, EWS has gotten even more strict about date formatting. The accepted answer formatting works for 2 digit months, but it does not for single digit months.
The formatting that works in all cases is:
DateTime.Today.AddDays(15).ToString("yyyy-MM-ddThh:mm:ssZ")
The restriction also works using the "Sortable date/time pattern".
Datetime.Now.ToString("s")
