Question

I try to do something like this.

8257,5321,0181,8279,8661,2120,6641,4000,0752,6975,9849,9106,7661,4522,4287,8613,3279,6296,4498,6003,8273,6642,5201
0 = 10
1 = 10
2 = 14
3 = 5
4 = 8
5 = 6
6 = 14
7 = 8
8 = 9
9 = 8
10=2, 14=2, 5=1, 8=3, 6=1, 9=1,

0 = 10, 2 = 14, 4 = 8
1 = 10, 6 = 14, 7 = 8

, 9 = 8

6235,5507,0126,9753,0354,0423,0328,6185,8449,3424,1481,1861,3234,5928,3503,1966,0513,2306,2315,3750,0190,1510,0063

  1   = 12,        4   = 8

5 = 12, 6 = 8

@MiPakTeh , Sorry for the late response, based on my test, I make a code example for you to ahieve your requirement.

  private void button1_Click(object sender, EventArgs e)  
        {  
            foreach (var item_ in Data1)  
            {  
                listBox2.Items.Add(item_);  
  
                var MyItems = new List<myItem>();  
  
                for (int j = 0; j <= 9; j++)  
                {  
                    String Number_ = j.ToString();  
                    int NumberCount_ = item_.Replace(",", "").ToCharArray().Count(c => c.ToString() == Number_);  
                    MyItems.Add(new myItem() { Index = Convert.ToInt32(Number_.ToString()), Value = NumberCount_ });  
                }  
  
                foreach (myItem ITM in MyItems)  
                {  
                    listBox2.Items.Add(ITM.Index + "   = " + ITM.Value);  
                }  
  
                var Result = new Dictionary<string, int>();  
                foreach (myItem ITM in MyItems)  
                {  
                    if (Result.ContainsKey(ITM.Value.ToString()))  
                    {  
                        Result[ITM.Value.ToString()] += 1;  
                    }  
                    else  
                    {  
                        Result.Add(ITM.Value.ToString(), 1);  
                    }  
                }  
  
                string List = "";  
                foreach (KeyValuePair<string, int> KV in Result)  
                {  
                    List += KV.Key + "=" + KV.Value.ToString();  
                    List += ", ";  
                }  
  
                listBox2.Items.Add(List);  
  
                foreach (KeyValuePair<string, int> KV in Result)  
                {  
                    string duvalue = string.Empty;  
                    if (KV.Value>1)  
                    {  
                        var result = MyItems.Where(m => m.Value.ToString() == KV.Key);  
               
                        foreach (var item in result)  
                        {  
                            duvalue += item.Index + "= " + item.Value+" ,";  
                          
                        }  
                        listBox2.Items.Add(duvalue);  
                    }  
                  
                }  
                listBox2.Items.Add("==============================");  
  
            }  
        }  

Result:

Hope the above code could help you.

Looks like you want a count for each number, perhaps the following will work for you, done in this case for a single string. To use while iterating lines in a file call the code for each line.

public static List<Item> GetAllItems(string values)  
{  
    var itemsGroup = (  
            from chr in values.ToCharArray()  
            group chr by chr into grp  
            select new Item  
            {  
                Character = grp.Key,  
                Occurrences = grp.Count(),  
                Code = Convert.ToInt32((int)grp.Key)  
            })  
        .ToList()  
        .OrderBy(item => item.Character.ToString());  
  
    return (from item in itemsGroup select item).ToList();  
  
}  

See full code in the following repository.

private void ReadFileButton_Click(object sender, EventArgs e)  
{  
    List<Item> GetInfo(List<List<Item>> list, int findChar)  
    {  
        var items =   
            (  
                from sublist in list   
                from item in sublist   
                where item.Character == findChar select item).ToList();  
        return items;  
    }  
  
    List<List<Item>> itemList = Operations.ReadFromFile();  
      
    var one = GetInfo(itemList, '1').Sum(x => x.Occurrences);  
    var eight = GetInfo(itemList, '8').Sum(x => x.Occurrences);  
    Console.WriteLine($"1 = {one,-4}8 = {eight}");  
  
}
