Select last element quickly after a .Split()

Question

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#?

Answer 1

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...

Answer 2

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
