如何在大型文本文件中搜索字符串而不在C＃中逐行查找？ [英] How do you search a large text file for a string without going line by line in C#?

问题描述

我有一个大的文本文件，需要搜索特定的字符串。

I have a large text file that I need to search for a specific string. Is there a fast way to do this without reading line by line?

这种方法非常慢，因为文件大小很大（大于100 MB）。

/ p>

This method is extremely slow because of the size of the files (more than 100 MB).

推荐答案

鉴于文件的大小，您真的要事先将它们全部读取到内存中吗？逐行可能是这里最好的方法。

Given the size of the files would you really want to read them entirely into memory beforehand? Line by line is likely to be the best approach here.
