Thread: FindAll Error

I would, personally, just use a lambda for the predicate:

Code:

            List<string> files = new List<string>(new string[] { "blah.c", "info.txt", "foo.c", "slapmesilly.der", "bar.h" });

            List<string> specificFiles = files.FindAll(f => f.EndsWith(".c") || f.EndsWith(".h"));

            foreach (string file in specificFiles)
                Console.WriteLine(file);

Result:

Code:

blah.c
foo.c
bar.h

Of course, I prefer LINQ, which works on any type that implements IEnumerable<T>. Using the following code you get the same results as above:

Code:

            string[] files = { "blah.c", "info.txt", "foo.c", "slapmesilly.der", "bar.h" };

            foreach (string file in files.Where(f => f.EndsWith(".c") || f.EndsWith(".h")))
                Console.WriteLine(file);
