Longest_common_substring

This is a project that shows how to find the longest common substring in an array of strings.

Usage

Just import the project to Visual Studio and rebuild.

There is a test_custom function that can be used to perform customized tests. The way to use it is

test_custom(new[] { "20010LEDMG WH RFR1", "20010LEDMG WH RFR2", "20110LEDMG WH 123" });

where the input is an array of strings that will be tested. This function will make a test and show the longest substring.

Code

In case you need an implementation of the function to check for the longest substring (and no the test), you can invoke it as

string[] str = new[] { "hab-a-b-c-h", "hab-a-b-c-d", "hab-a-b-cd-e", "hab-a-b-c-d" };
string mostCommonSubstring = str.GetMostCommonSubstrings().FirstOrDefault();

where mostCommonSubstring will contain the looked substring.

There is a class called StringExtensions.cs. Just import it to your project, modify the access level if necessary (by default is public) and invoke it from any string[] object.
