I want to compare list1 and list2 and then create a list3 that contains all contigs in list1 minus those also present in list2. Is this poss...
Hi, Consider the following straightforward implementation of a list in latex: \newcommand{\add@to@list}[2]{% \ifx#2\@empty% \xdef#2{#1}% \else% \xdef#2{#2,#1}% \fi% }% I wonder if there is a simple way to implement a set (list with no repeated elements) ? ...
Is there any way to tell via reflection that a generic list of Type A is related to a generic list of Type B? For example, I have a List<string> and a List<int>. How can I tell via reflection that both these types are 'instances' of List<T>. I think I'm having a problem because List<T> isn't a real type. You can't do typeof(List<T>) ...

Hi there, I have a draggable list (.field) where you can drag & drop items from it into a sortable list (.sortlist). I did it this way because I didn't want the master list (.field) altered in any way. It works fine, except I cannot work out how to manipulate the dropped field in a sortable list. I can do it from a draggable into a dr...

I'm trying to find the best approach to filtering a list with C# (3.5) but I can't seem to find any examples that are similar to my situation. I'm open to using lambdas or linq.
