string split in c#

开发者 https://www.devze.com 2023-01-25 08:15 出处:网络
I have strings like this: 00123_MassFlow 0022245_VOlumeFlow 122_447_Temperature I have to split these strings with _ using C#. _ may appear multiple places but i have to take last value.

I have strings like this:

    00123_MassFlow
    0022245_VOlumeFlow
    122_447_Temperature

I have to split these strings with _ using C#. _ may appear multiple places but i have to take last value.

My should be like this:

    MassFlow
    VOlumeFlow

How i can achieve this?


"122_447_Temperature".Split('_').Last();

If you don't mind the extra overhead of creating an array and throwing away a bunch of strings. It won't be as fast as using LastIndexOf and Substring manually, but it's a ton easier to read and maintain, IMO.


If your input is in a single string, you can use string.Split('\n') to get it into a collection:

string input = @"00123_MassFlow
0022245_VOlumeFlow
122_447_Temperature";

var items = input.Split('\n');

Otherwise, I'm going to assume your strings are already in a collection called items. From there, you can use LINQ to accomplish this easily:

List<string> result = (from x in items
                       let y = x.Trim()
                       select y.Substring(y.LastIndexOf('_') + 1)).ToList();

result will contain the strings MassFlow, VOlumeFlow, and Temperature.
