C#从末尾删除整个字符串

Question

I want to be able to remove the entire start of a string except for just the end. For example:

http://www.website.com/images/a_image.png

That is my url/string. I want to remove most of the first bit of the string so it will end up being.

a_image.png

What is the most reliable and efficient way to do this?

Answer 1

Uri myuri = new Uri("http://www.website.com/images/a_image.png
");

String last_part = myuri.Segments[myuri.Segments.Length-1];  

or

String last_part = myuri.Segments.Last();

Answer 2

Path.GetFileName will do this for you.

Path.GetFileName("http://www.website.com/images/a_image.png");

Returns

a_image.png

Answer 3

string str="http://www.website.com/images/a_image.png";
str=str.Substring(str.LastIndexOf("/")+1);

Answer 4

Assuming what you want is to get the final part of your URL (ie the value after the last / character), then you can use the String.LastIndexOf(...) method. So you could do something like the following:

string url = @"http://www.website.com/images/a_image.png";

int breakIndex = url.LastIndexOf('/');
string lastFragment = url.Substring(breakIndex + 1);

This will give you the result of "a_image.png".

Answer 5

Try

var str = "http://www.website.com/images/a_image.png";
var reqdstr = str.Split('/')[str.Split('/').Count()-1];

Answer 6

Simple way (quite unsafe tho):

string a = "http://www.website.com/images/a_image.png";
string b = a.Remove(0, a.LastIndexOf("/") + 1);

Answer 7

Split the URL string based on forward slash (/) which will return an array containing various components of the URL. Use the last index(array.length -1) which will fetch you the image
