Suppose I wanted to query this list...

I converted it to a list since the docs.
Sorry, I mistyped:
var q = from Field f a List of distinct object names from the list as defined.
To query the list fieldList, not just the class field.

Something along the lines of
Dim dic as New Dictionary(Of TypeOfYourValues, List(Of Foo)) For Each e As Foo In myList If Not dic.ContainsKey(e.PropertyA) Then dic(e.PropertyA) = New List(Of Foo = from foo in list group foo....

If I have this:
a='abcdefghij' b='de'
Then this finds b in a:
b in a => True
Is there a way of doing an similar thing with lists? Like this:
a=list('abcdefghij') b=list('de') b in a => False
The 'False' result is understandable - because its rightly...

So, if you aren't concerned about the order the subset appears, you can do:
a=list('abcdefghij') b=list('de') set(b).issubset(set(a)) True
Edit after you clarify: If you need to preserve order, and the list is indeed characters as....

public class myObject { public int ID { get; set; } public List<mySetting> setting { get; set; } } public class mySetting { public int ID { get; set; } public...

OrderBy is slightly easier than Sort :
var sorted = lmo.OrderBy(x => x.Value);
but even Sort isn't too bad:
lmo.Sort((x, y) =>... .
Well, List<T> already has a Sort method if you want to sort it in place - or you could use LINQ's OrderBy method .

If I want to search the...

Int index = list.FindIndex(m => m.Member == someMember);
If you can use Linq
SomeClass aClasss = list.FirstOrDefault(item => item.Member == someMember); .

In C++ using std::list, this is a simple matter of erasing what an iterator is pointing to (the erase statement returns the next valid member of the list).
What's the best way to iterator through a list and remove members that match a certain criteria...

In another list and next delete them in loop
But here is the cookie: http://www.koders.com is to iterate through the list in reverse order, removing items as you go:
for(int i = myList.Count-1 IEnumerable<T> , it gets more difficult....

I'm partial to using member initialization lists with my constructors... but I've long since forgotten the reasons behind this...
Do you use member initialization lists in your constructors? If so, why? If not, why not?

Furthermore, if a class doesn't have a default constructor, or you have a const member variable, you must use an....
In the initializer list:
B() : a(3) { }
This would only call A 's A(int) constructor and not its default that unnecessarily.

Hey there,
I'm trying to figure out what the best way to show a list of members (users) that aren't a collection (group).
/users

/group/:id/members

Support a representation consisting of a list of users and their respective groups (the resource found available_users representation for any group is likely to be only slightly smaller than the entire list.

In Visual Studio there is a drop down list in the top right hand corner that you can use to navigate to the various members in the class. Does anyone know if there is a hot key to open this ddl?
