c# - IComparer for string that checks if x starts with y -

i've got array of strings , need strings, start 'prefix'. wanna use array.binarysearch(). possible? , how should write comparer if so?

no, cannot use binarysearch in case. use enumerable.where instead:

dim query = str in array str.startswith("prefix")

or (ugly in vb.net) method synatx:

query = array.where(function(str) str.startswith("prefix"))

edit: whoops, c#

var query = array.where(s => s.startswith("prefix"));

use toarray if want create new filtered array.
