Select last element quickly after a .Split()
I have this code :
stringCutted = myString.Split("/"). // ???
and I'd like to store in stringCutted
the last element of the string[]
after the split, directly, quickly, without storing the splitted array in a variable and access to that element with array[array.length]
.
Is this possible in C#?
If you're using .NET 3.5 or higher, it's easy using LINQ to Objects:
stringCutted = myString.Split('/').Last();
Note that Last()
(without a predicate) is optimized for the case where the source implements IList<T>
(as a single-dimensional array does) so this won't iterate over the whole array to find the last element. On the other hand, that optimization is undocumented...
stringCutted=myString.Split("/").Last()
But, just FYI, if you're trying to get a filename from a path, this works heaps better:
var fileName=System.IO.Path.GetFileName("C:\\some\path\and\filename.txt");
// yields: filename.txt
Since you want a solution that returns the last element directly, quickly, without store the splitted array, i think this may be useful:
stringCutted = myString.Substring(myString.LastIndexOf("/")+1);
