在文本文件中搜索多个关键字 [英] Searching muliple keywords in a text file

问题描述

大家好，



我需要在一个巨大的多个文本文件中搜索大约90000个关键字。我已经实现了这个功能，但是由于需要扫描大量的关键字，这个过程需要很长时间。

目前我已经实现了一个for循环并扫描所有文本文件中的每个关键字但是这个过程很好，关键字数量很少。现在，当我的关键字增长时，这需要很长的时间。



任何人都可以提供一些解决方案来最小化此要求所需的时间

Hi all,

I have some 90000 keywords that I need to search on a huge multiple text files. I have implemented this functionality, but due to the huge number of keyword to be scanned the process takes a long time.
Currently I have implemented a for loop and scan each and every keyword on all the text files but this process was fine with small number of keywords. Now when my keywords grew this takes a huge time.

Can anyone provide some resolution to minimize the time required for this requirement

嗨试试这个，

hi try this,

string StrValue_FD = "Hello hi Hi hello length and are you length hi.";

            var split = StrValue_FD.ToUpper().Split(' ');
            int length = split.Length;

            List<string> list = new List<string>();

            while (length > 0)
            {
                list.Add(split[length - 1]);
                length--;
            }

            var result = list.GroupBy(str => str).ToDictionary(str => str.Key, str => str.Count());</string></string>

你可以尝试这个例子。结果你可以得到每个单词的出现次数。

you can try this example. In result you can get the each word number of times occured.
