Dictionary is a pain, since it doesn't implement IList (something I was moaning about just the other evening). It really comes down to what you have available. Resolving the Add method for int/string is easy enough, but if you are dealing with typical list reflection you'll need the Add method from ICollection<KeyValuePair<int,string>>.

For standard usage:

object data = new Dictionary<int, string>();
object key = 123;
object value = "abc";
var add = data.GetType().GetMethod("Add", new[] {
          key.GetType(), value.GetType() });
add.Invoke(data, new object[] { key, value });
