Solution 1

If you are using .Net 3.0 (or higher), use LINQ.

There are some good count samples here[^]. Check if any of them suits you (the count by group one specifically).

If you post some code here, members would be able to provide more details on how you should go about your solution.

If you're not using LINQ, you could just use a dictionary to do such.

Ex.

Dictionary<string, int> dict = new Dictionary<string, int>();
int intCount;
 
foreach (string strValue in values)
{
  if (dict.TryGetValue(strValue, out intCount))
    dict[strValue] = ++intCount;
  else
    dict[strValue] = 1;
}

Something like that...after you're done, the dictionary will have all the unique values as keys and the counts of how many for each in the value portion.
