The GetInterface method searches for an interface only by name (using a case-sensitive or case-insensitive search), and the GetInterfaces method returns an array of all the interfaces implemented on a particular type. To execute a more focused search—for example, searching for interfaces that ...
This sample uses case-insensitive nested ordering, with a custom comparer to sort first by word length and then by a case-insensitive sort of the words in an array. //c# static void Linq36() { var words = new [] { "aPPLE", "AbAcUs", "bRaNcH", "BlUeBeRrY", "ClOvEr", "cHeRry" ...
