读取文件中的特定行 [英] Reading specific line in file

问题描述

如何从文件中读取一行?当我想写文件时，只需创建FileStream和FileWriter并写一行.但是，如果我想阅读一些特定的行怎么办?我注意到FileReader也存在，但没有发现如何使用它.
对于这样的菜鸟问题，我很抱歉，我仅几天就学习C#.感谢您的帮助.

好吧，它应该看起来像str = streamReader.ReadLine();.但是如何指定要阅读的行?找不到如何使用ReadLine和msdn的解释是不好的:(

Hi,
How to read one line from file? When I want to write to file its simply I just create FileStream and FileWriter and write line. But what if I want to read some specific line? I''ve noticed that FileReader exists too but didn''t found nowhere how to use it.
I''am sorry for such noob question I''am learning C# just few days. Thanks for any help.

Well so it should look like str = streamReader.ReadLine(); but how can I specify what line I want to read? Can''t find how to use ReadLine and msdn explanation is bad :(

推荐答案

要从文件/流中进行面向行的读取，请使用System.IO.StreamReader:

For line-oriented reading from file/stream, use System.IO.StreamReader:

从文件读取行是线性的，仅向前的过程.换句话说，如果您想读取行号N，则读取行1到N-1(如果不需要则将它们丢弃)，然后下一行将是行N.

Reading lines from a file is a linear, forward only process. In other words, if you want to read line number N, you read lines 1 through N-1 (and throw them away if you don''t need them) and then the next line read will be line N.
