You can use a combination of string.Join and Select:
string.Join("&", ages.Select(age => $"ages={age}"));

To do proper URL encoding, you can use HttpUtility.ParseQueryString() like this:
var query = System.Web.HttpUtility.ParseQueryString(string.Empty);
foreach (var age in ages)
{
query.Add("ages", age.ToString());
}
// or: ages.ToList().ForEach(age => query.Add("ages", age.ToString()));
return query.ToString();
However, this will lead to ages=123,234.
agesconstant in request must the same of the variable name or i can use constant likeages?
