ilist

What is the most suitable container just for strings holding in some array with non-predetermined upper boundary, which length is unknown on it's creation. For simple code like: var list = new SomeContainer(); // size is unknown for()/foreach()/do()/while() // any loop { list.Add(string); } Is it StringCollection as optimized Collection for string, or just Collection<string> or List<string> or ArrayList ? What is the different between them? For what you need, List<string> is probably the most versatile. StringCollection was handy in 1.1, when (without generics) you needed specific classes for

What is the correct syntax for this: IList<string> names = "Tom,Scott,Bob".Split(',').ToList<string>().Reverse(); What am I messing up? What does TSource mean? The problem is that you're calling List<T>.Reverse() which returns void . You could either do: List<string> names = "Tom,Scott,Bob".Split(',').ToList<string>(); names.Reverse(); or: IList<string> names = "Tom,Scott,Bob".Split(',').Reverse().ToList<string>(); The latter is more expensive, as reversing an arbitrary IEnumerable<T> involves buffering all of the data and then yielding it all - whereas List<T> can do all the reversing "in

Update 2011-Jan-06: Believe it or not, I went ahead and incorporated this interface into an open source library I've started, Tao.NET . I wrote a blog post explaining this library's IArray<T> interface, which not only addresses the issues I originally raised in this question (a year ago?!) but also provides a covariant indexed interface , something that's sorely lacking (in my opinion) in the BCL. Question (in short): I asked why .NET has IList<T> , which implements ICollection<T> and therefore provides methods to modify the list ( Add , Remove , etc.), but doesn't offer any in-between

I have a function that returns an IList< T > and is the DataSource for a DataGridView. I learned that DataGridView won't sort IList. I read This stackoverflow Q&A and am trying to implement SortableBindingList. I must be doing something wrong because my DataGridView is empty. I also tried to access an element from the SortableBindingSource with a TextBox and nothing as well. using Microsoft.SqlServer.Management.Controls; public partial class Form1 : Form { IBusinessLayer businessLayer; IList<Category> categories; SortableBindingList<Category> catSortable; public Form1() { InitializeComponent()

So I came across an interesting problem today. We have a WCF web service that returns an IList. Not really a big deal until I wanted to sort it. Turns out the IList interface doesn't have a sort method built in. I ended up using the ArrayList.Adapter(list).Sort(new MyComparer()) method to solve the problem but it just seemed a bit "ghetto" to me. I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method as well as casting to a List but none of these seemed overly elegant. So my question is, does anyone have an elegant solution to sorting an
