how to pass list as parameter in function

I have taken a list and insert some value in it

public List<DateTime> dates = new List<DateTime>();         
DateTime dt1 = DateTime.Parse(12/1/2012);
DateTime dt2 = DateTime.Parse(12/6/2012);
if (dt1 <= dt2)
{                              
    for (DateTime dt = dt1; dt <= dt2; dt = dt.AddDays(1))
    {
        dates.Add(dt);                    
    }       
}

Now I want pass this List i.e dates as a parameter to some function like-

somefunction(dates);

How exactly can i achieve this?
