I have a collection of strings:
/a/b/111.txt
/a/b/c/222.txt
a/b/333.txt
a/b/c/d/444.txt
I want to this collection to be ordered like this:
/a/b/111.txt
a/b/333.txt
/a/b/c/222.txt
a/b/c/d/444.txt
So all a/b are grouped together, and so on.
Can this be done using linq? Or some other way?
Given
var input = new []
{
@"/a/b/111.txt",
@"/a/b/c/222.txt",
@"a/b/333.txt",
@"a/b/c/d/444.txt",
};
you can "normalize" the strings by removing the leading / (if any) and use that as sorting key:
var output = input.OrderBy(s => s.TrimStart('/')).ToList();
You can achieve this by removing all slashes from the string being compared:
items.OrderBy(item => item.Replace("/", ""));
You can do this,
List<string> values = new List<string>();
values.Add("/ a /b/111.txt");
values.Add("/ a / b / c / 222.txt");
values.Add("a / b / 333.txt");
values.Add("a / b / c / d / 444.txt");
var sortedList = values.OrderBy(p => p.Count(c => c == Path.DirectorySeparatorChar || c == Path.AltDirectorySeparatorChar));
Working .Net Fiddle
/p/q/222.txt at the beginning of your sequence, it can be ordered as one of the first elements
Path.GetDirectoryName(inputStringPathHere)?data.OrderBy(x => x.Split('/').Length)?
