Get string between specific character

Question

I have a string: "https://mhnkp2.com/src/vid/pra/Tentang_Mata-Cerita_Boneka-Prasekolah.mp4"

I want to get only "Tentang_Mata-Cerita_Boneka-Prasekolah"

I try to use code:

string path = "https:\/\/mhnkp2.com\/src\/vid\/pra\/Tentang_Mata-Cerita_Boneka-Prasekolah.mp4"
int start = path.IndexOf("/") + 5;
int end = path.IndexOf(".", start);
string result = path.Substring(start, end - start);

But the result is only "kp". How to handle it?

Answer 1

您可以使用

System.IO.Path.GetFileNameWithoutExtension("https://mhnkp2.com/src/vid/pra/Tentang_Mata-Cerita_Boneka-Prasekolah.mp4")

Answer 2

You could use one of these ways :

First, separate the string part :

var originalValue = @"https://mhnkp2.com/src/vid/pra/Tentang_Mata-Cerita_Boneka-Prasekolah.mp4";

        var startPoint = originalValue.LastIndexOf('/') + 1 ;
        var endPoint = originalValue.Length - startPoint;
        var splitedValue = originalValue.Substring(startPoint, endPoint);
        var dotIndex = splitedValue.LastIndexOf('.');
        var extension = splitedValue.Substring(dotIndex, splitedValue.Length - dotIndex);

        var finalValue = splitedValue.Replace(extension, string.Empty);

Second, using .Net library :

var result = System.IO.Path.GetFileNameWithoutExtension("https://mhnkp2.com/src/vid/pra/Tentang_Mata-Cerita_Boneka-Prasekolah.mp4")

Answer 3

Why you don't get only string started from last /

string s =  "https:\/\/mhnkp2.com\/src\/vid\/pra\/Tentang_Mata-Cerita_Boneka-Prasekolah.mp4";
string lastSegment = s.Split('/').Last();

so, you can get Tentang_Mata-Cerita_Boneka-Prasekolah.mp4 and remove l'extension to get file name
