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

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]);

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

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