Question

I have a multiselect dropdown called ID that submits ID=1,2,3 which I need parsed into an integer array to do a Contains() on in a filter method. At the moment I use:

string[] ids = Request["ID"].Split(',');

Which I don’t really like because its slower to compare string than int. Any suggestions?

Answer 1

Request["ID"].Split(',').Select(x=>int.Parse(x)).ToArray();

Of course, this will throw if any of the resulting numeric strings are not “parseable” (does such a word exist?).
