I have a comma separated string variable and i need to check its values exists in a given List

string freeServices = "1,7,13,21";
List<int> selectedServices = booking.SelectedServices.Select(x => x.ServiceID).ToList();

i have tried something like this

if (selectedServices.Contains(Convert.Int32(freeServices.Split(','))
{
}

You could use All and int.Parse;

string freeServices = "1,7,13,21";
List<int> selectedServices = booking.SelectedServices.Select(x => x.ServiceID).ToList();
var splittedFreeServices = freeServices.Split(',').Select(k => int.Parse(k));
var result = selectedServices.All(x => splittedFreeServices.Contains(x));
if (result) //booking.SelectedServices contains all elements of freeServices as integer
{

}

To check, all values are contained in SelectedServices:

string freeServices = "1,7,13,21";
var values = freeServices.Split(',').Select(o=>Convert.ToInt32(o)).ToList();

List<int> selectedServices = booking.SelectedServices.Select(x => x.ServiceID).ToList();

if (selectedServices.All(o=>values.Contains(o))
{
}
