I'm having a bit of a 'brain doner' moment here
I have a list of Objects. Each of these Objects contains a list of other Objects (pseudo code) :-
Private Structure Object1
dim Name as string
dim ListOfObject2 as List(Of Object2)
[Code]....
I need to sort the list of Object1 by the Value in Object2. I have a comparison class which sorts Object2 by its Value nicely.
I would like to create list of child objects from list of parent object. Like If i have list of bookingroom which has one member room then i would like to create list of room from it.
eg. code:
Dim BookingRoomList As List(Of BookingRoom) = New List(Of BookingRoom)
Dim RoomList As List(Of Room) = New List(Of Room)
BookingRoomList = BookingRooms.FillGrid()
[Code]....
Is there any short cut method instead of iterating over for earch?

View 1 RepliesI have a generic list, like this:
System.Collections.Generic.List<Question> myquestions = new System.Collections.Generic.List<Question>();
And I have a paging example, using a LINQ table acquried from database, doing this for paging:
var questions = context.Questions
.OrderBy(sidx + " " + sord)
.Skip(pageIndex * pageSize)
.Take(pageSize);
Right now, for paging my populated from code list, I have:
var questionss = myquestions
.OrderBy(x => x.Id)
.Skip(pageIndex * pageSize)
.Take(pageSize);
And what I want is being able to order "myquestions" by a string as in the above example. Is that possible?
how do I sort a list properly so the numbers are truly in order?

Limited to using v2.0 of .Net framework (we use VB.net) due to environmental constraints on our servers.I've got an ASP.net webpage which pulls data from a webservice that performs checks on user accounts in active directory. Operators can check multiple accounts at one time using the web interface. The webservice returns a list(of AccountCheck) objects which themselves contain single properties like username, email address, and List(of AccountError) objects which contain multiple properties.[code]What I want to do is using some kind of repeater, create multiple panels or divs which contain labels showing the username, email etc, and a gridview which has the accounterror list bound to it to show all the errors. The users could be checking 2, 5, 7 accounts at once, and is dynamic.
View 2 RepliesI made an object that has several properties one of which is an integer.
I put all the objects into a list, and I wish to sort that list by the integer property, with the object with the highest property at item 0, with the object with the lowest property at the highest item # ( count -1).
I made the list of that item, as in
Dim GameList as new list(of clsGame)
And I wish to do something like the following
GameList.Score.Sort()
What is the syntax to do that? I looked up the MSDN and didn't really understand what it was trying to say
I have a List (Of Type) which contains many instances of a class with three properties, IPAddress, AlertDate and AlertTime.There can be many duplicates of IPAddress in this list :-

What would be the fastest way to sort a list that contains a list of objects, based upon another list? An example follows:Say I have multiple lists of employees. Each individual list has a common property value, say "Department". So I have a list of employees, in one list they all have the department string value of "Sales". In another list all the objects have a department value of "Finance". These lists of employees are then contained in a list which holds them all.
I have a second list, which should drives the sort order of the employee lists. The second list simply contains a list of strings like, "Finance", "Sales", "IT" and so on. I'd like my lists of customers to be sorted in the order of "Finance", "Sales", etc.I'm using VB.NET in .NET 2.0

I have a List(Of T) storing a list of Custom classes called Advertisement. Each advertisement contains 3 properties, Year, Make and Model. I need to sort the list By Year, then by Make and then by Model. I have a property in the Advertisement class called Vehicle which returns a formatted string with the Year Make Model like 2007 Toyota Tacoma and ive been sorting on that but its not working how I thought it would. Basically I want to sort the list by Year (decending; lowest year first) then sort by the Make and Model (in alphabetical order) Is that even possible? Here is the code ive been using.

View 4 RepliesMy task is to create buttons to demonstrate how loops work on a form. Two numbers are entered and validated (lower bound and upper bound). They are then to display all the numbers between them in an "odds list box" and an "evens list box" in ascending order. If however, the lower bound number is higher than the upper bound number - they are to be displayed in the list boxes in "descending order". My code for the "For...Next...Loop" worked fine - but I am having trouble with the "Do While Loop". I can not seem to determine how to have it displayed in descending order.[code]...
