If string=aabbccc and Int 2

output=ccc ......It will remove aabb as their count match with enter int.

If string=aaabbccc and Int 3

output=bb

If string=aaabbccc and Int 1

output=aaabbccc output will be same as none of the character match with entered string.

If string=abc Int 1

output= output will be empty as the as all character matched with entered string

We can achieve this by using LINQ as follows,
public static void RemoveChars(string str, int count)
{
try
{
//group the string based on character and filter those with the passed integer value
var lst = str.ToCharArray().ToList().GroupBy(p => p).Select(a => new { key = a.Key, cnt = a.Count() }).Where(q => q.cnt != count).Select(c => c.key).ToList();

//filter the remaining charter value from passing string and get the array
var r = str.ToCharArray().Where(p => lst.Contains(p)).ToArray();
//print string from result char array
Console.WriteLine(new string(r));
}
catch
{
throw;
}
}

1. static void removeduplicate(string str,int opt)
2. {
3. string s = "";
4. char[] chrs = str.ToArray();
5. if(opt == 3)
6. {
8. for (int i = 0; i < chrs.Length; i++)
9. {
10. if ((i <= chrs.Length - 3))
11. {
12. if ((chrs[i] == chrs[i + 1] && chrs[i] == chrs[i + 2]))
13. {
15. i = i + 2;
16. }
17. else
18. {
19. s += chrs[i];
20. }
21. }
24. else
25. {
26. s += chrs[i];
27. }
28. }
30. Console.WriteLine(s);
31. }
32. }
