simple solution for characters frequency in string object

Question

The task what I\'m trying to do is about showing up the frequency of every single characters from the string object, for the moment I\'ve done some part of code, just doesn\'t h

Answer 1

You can easily do it using Linq like:

 string sign = "attitude";
 int count = sign.Count(x=> x== 'a');

or if you want all characters count then:

 string sign = "attitude";
 var alphabetsCount = sign.GroupBy(x=> x)
                          .Select(x=>new 
                                    {
                                      Character = x.Key, 
                                      Count = x.Count()
                                    });

Here is a working Example

UPDATE:

Without Linq you can do it with a loop and track it in a dictionary like:

string sign = "attitude";
Dictionary dic = new Dictionary();
foreach(var alphabet in sign)
{
    if(dic.ContainsKey(alphabet))
        dic[alphabet] = dic[alphabet] +1;
    else
        dic.Add(alphabet,1);
}

Here is Demo without Linq using Dictionary<>
