How could I instantiate the Flights in one line?
public class Flights
{
public RouteInformation routeInformation { get; set; }
public string FlightNumber { get; set; }
}
public class RouteInformation
{
public string Origin { get; set; }
public string Destination { get; set; }
}
I want to instantiate the Flights in one line
var flights = new Flights {
new RouteInformation
{
Origin="IKA",
Destination="IST"
},
FlightNumber="123",
};
But I got Invalid initializer member declarator.

var flights = new Flights {
routeInformation = new RouteInformation
{
Origin="IKA",
Destination="IST"
},
FlightNumber="123",
};
You forgot "routeInformation ="

How can I define classes with properties where the following code would compile and be valid?
AtomEntry newPost = new AtomEntry();
newPost.Title.Text = "Marriage!";
newPost.Content = new AtomContent();
newPost.Content.Content = "<div xmlns='http://www.w3.org/1999/xhtml'>" +
"<p>Mr. Darcy has <em>proposed marriage</em> to me!</p>" +
"<p>He is the last man on earth I would ever desire to marry.</p>" +
"<p>Whatever shall I do?</p>" +
"</div>";
newPost.Content.Type = "xhtml";

This should do it:
public class AtomEntry
{
public AtomContent Content { get; set; }
public Title Title { get; set; }
}
public class AtomContent
{
public string Content { get; set; }
public string Type { get; set; }
}
public class Title
{
public string Text { get; set; }
}

my task is to group the data from a list of Subscription object which has the following structure:
public class Subscription
{
public string ApplicationId { get; private set; }
public string UserCode { get; private set; }
public string SubscriptionId { get; private set; }
public string SubscriptionCode { get; private set; }
public DateTime? StartDate { get; private set; }
public DateTime? EndDate { get; private set; }
}
The code return a list of subscription, so List. In my case I've several items with same ApplicationId but different StartDate and EndDate. Basically I have to group these items
in order to create a json structure like this:
"applicationId" : {
"subscriptions" : [
{
"startdate" : ...,
"enddate" : ...,
},
{
"startdate" : ...,
"enddate" : ...,
},
]
}
Can I achieve this using LINQ?

Try this:
subscriptions.GroupBy(item => item.SubscriptionCode)
.Select(group => new { Subscription = group.Key, Items = group.Select(item => new { StartDate = item.StartDate, EndDate = item.EndDate}) })
Not sure if it will work but it reads like it will.
subscriptions is just a list of your object.

I have three classes :
public class QData
{
public List<RData> Items { get; set; }
public List<QDay> Dates { get; set; }
}
public class QDay
{
public string Date { get; set; }
public List<RData> Details { get; set; }
}
public class RData
{
public string Name { get; set; }
public int Quantity { get; set; }
}
my list is
List<QData> myList;
What is the most effective way to sort the list (*QData type) by Date, the Date is string.

Perhaps this is what you need:
var result = myList.Select(qData => new QData()
{
Items = qData.Items,
Dates = qData.Dates.OrderBy(qDay => DateTime.Parse(qDay.Date)).ToList();
}).ToList();
With DateTime.Parse call being perhaps modified to fit to the date format in the qDay.Date property.

Here is an example that sort using the first date in the Dates list. I can't imagine why you would ever want to do this but here it is. I suspect that having Dates be a list is a mistake, in fact you only want one date there.
var sortedList = MyList.OrderBy(element => DateTime.Parse(element.Dates.First().Date));
I think this is what you actually want... ONLY ONE LIST:
public class QData
{
RData itemInfo { get; set;}
QDay dateInfo { get; set; }
}
Then your sort would look like this:
var sortedList = MyList.OrderBy(element => DateTime.Parse(element.dateInfo.Date));

var temp = (from e in myList.Dates
orderby DateTime.Parse(e.Date)
select e
).ToList();
myList.Dates = temp;
