How can I split the following string on "\" and/or "/" using LINQ
I say and/or for "\" and "/" because in my file paths, I might end up getting forward slashes only, backslashes only or a mix of both.
"temp\\SimpleRec/bin/Debug/Geming.SimpleRec.vshost.exe"
"temp\\SimpleRec\\bin\\Debug\\Geming.SimpleRec.vshost.exe"
"temp/SimpleRec/bin/Debug/Geming.SimpleRec.vshost.exe"
Thanks
String.Split() seems to be the best option here, but just for fun it is also possible to do with LINQ.
One of my implementations of String Calculator Kata uses this approach (no Split at all). See InternalAdd() method. I took functional approach with head and tail. You divide string to head and tail using .Take() and return head + recursive result of calling the same function for tail.
Sample code for one char delimiter is below (things are getting complicated when delimiters are getting longer):
private IEnumerable<string> BreakString(string source)
{
var delimiter = '/';
var head = source.TakeWhile(c => c != delimiter);
if (!head.Any())
{
yield break;
}
var tail = source.SkipWhile(c => c != delimiter)
.Skip(1);
yield return String.Join("", head);
foreach (var t in BreakString(String.Join("", tail)))
{
yield return t;
}
}
// usage
from s in BreakString(source)
You can also go further and get rid of String.Join() by tail.Aggregate(new StringBuilder(), (sb, c) => sb.Append(c)).ToString();
String.Split may be complicated as well.String.Split as overly complex :)You don't need LINQ for this:
string[] values = myString.Split(new []{'\\', '/'});
Introducing LINQ for such a task just adds complexity and reduces readability.
Sometimes, I think that LINQ is attempted to be used for everything, when it doesn't.
string[] data = myString.Split(new Char[]{'\\', '/'});
There's no need to use LinQ here, the default Split() method will do the work:
var path = "temp\\SimpleRec/bin/Debug/Geming.SimpleRec.vshost.exe"
var parts = path.Split(new[] { '/', '\\' });
Hope this helps!
You can split using LINQ by following way:
var list=from item in str.Split(new string[] { "\\","/" }, StringSplitOptions.None)
select item;
str.Split(new [] { "\\","/" }, StringSplitOptions.None)No LINQ required, simply do this:
var path = @"temp\\SimpleRec/bin/Debug/Geming.SimpleRec.vshost.exe";
var split = path.Split(new [] { '/', '\\' }, StringSplitOptions.RemoveEmptyEntries);
