[英]C# - trim text file contents to specified line number
I have a very annoying bug, code generation tool has generated like 20,000 lines of rubbish in file. 我有一个非常烦人的错误,代码生成工具已在文件中生成了20,000行垃圾。 Removing it all by hand, is, well, rather hard, so I want to write a program that does so.
用手将其全部删除非常困难,所以我想编写一个程序来删除它。 Good news is that source code file contains needful info on lines 1 - 300, and then rubbish all the way down to line 20,000.
好消息是,源代码文件在第1-300行包含必要的信息,然后一直到20,000行都包含垃圾。
I'm not very experienced in handling files in C#, and couldn't google up method I need. 我在C#中处理文件的经验不是很丰富,也无法用谷歌搜索所需的方法。 Are there any ways to do so?
有什么办法吗?
File.WriteAllLines("test.txt", File.ReadAllLines("test.txt").Take(300));
Below is an example code to do this file trimming: 以下是执行此文件修剪的示例代码:
public static void TrimFile(string fileName,int start, int end)
{
File.WriteAllLines(fileName,
File.ReadAllLines(fileName)
.Skip(start - 1).Take(end - start));
}
