读取文本文件中的特定行 [英] Read specific line in text file

问题描述

好的，我有一个程序需要从类似这样的文本文件中读取数据

Ok so I've got a program that needs to read from a text file that looks like this

[Characters]
John
Alex
Ben

[Nationality]
Australian
American
South African

[Hair Colour]
Brown
Black
Red

我想做的是只有一种方法可以根据传递的参数读取一个部分.

What I would like to do is only have one method that reads a section depending on the parameter that is passed.

这可能吗?如何实现?

推荐答案

var sectionName = "[Nationality]";
string[] items = 
    File.ReadLines(fileName)                           //read file lazily 
        .SkipWhile(line => line != sectionName)        //search for header
        .Skip(1)                                       //skip header
        .TakeWhile(line => !string.IsNullOrEmpty(line))//take until next header
        .ToArray();                                    //convert to array

items 将有:

Australian 
American 
South African
