Hi friends, i have one task, in this i need to generate list.

C#

foreach (Match m in mc)
           {
               if (m.Groups[1].Value.Trim().Contains(" "))
               {
                   string[] arr = m.Groups[1].Value.Split(' ');
                   foreach (string s in arr)
                       if (!clsList.Contains(s)) clsList.Add(s);
               }
               else
                   if (!clsList.Contains(m.Groups[1].Value)) clsList.Add(m.Groups[1].Value);
           }

in this mc is a match collection, in this i need to convert as list with mc.groups[1].value, then if group value contains space means that must be split and add with list, now only i using foreach loop.

What I have tried:

Can you show the text and the regular expression?
I'm not sure you are on the right track here.

Solution 1

try this

C#

mc.OfType<Match>().ToList().ForEach(m => { clsList.AddRange(m.Groups[1].Value.Split(' ')); });
      clsList = clsList.Distinct().ToList();

Solution 2

Similar to Karthik's solution:

C#

clsList = mc.OfType<Match>().SelectMany(m => m.Groups[1].Value.Split(' ')).Distinct().ToList();
