字符串比较，返回最相似

Question

Search substrings from a string and get a substring that matches the most!

string [] allModels = { "Galaxy", "S3", "Galaxy S3" };
string title = "Samasung galaxy s3 is for sale";
string[] title_array = title.Split(' ');
string model = "";
foreach(var tit in title_array)
{
      foreach(var mod in allModels)
      {
             if (mod.Equals(tit, StringComparison.OrdinalIgnoreCase))
             {
                   model = mod;
             }
      }
}

The model selected is Galaxy but I need Galaxy S3 (ie, most similar). How can I get Galaxy S3 .

Should I use Array.FindAll(target) method?

Update:

By most similar I mean the substring (model) that matches the most from string(title)

eg, in galaxy Samasung s3 is for sale the model should be galaxy s3 (according to above allModels array)

Answer 1

Most similar? don't have to be Search substrings from a string and get a substring that matches the most! I'll presume you want a longest match...

string[] allModels = { "Galaxy", "S3", "Galaxy S3" };
string title = "Samasung galaxy s3 is for sale";

var mod = allModels.OrderByDescending(x => x.Length)
          .FirstOrDefault(x => title.IndexOf(x,StringComparison.OrdinalIgnoreCase)>=0);

Answer 2

Here is a way to find the model containing the most words of the title.

var allModelsList = new List<String>(allModels);
var titles = new List<String>(title_array);
allModelsList.OrderByDescending(model => titles.Where(title => title.Equals(model, StringComparison.OrdinalIgnoreCase)).Count()).FirstOrDefault();
