    The easiest way would be splitting your list of IDs:

    ...
string.Format("Send IN {0}", string.Join(sendList.Select(id => id.ToString()));

    But if you insist on a parameter, you can write an SQL function that convert your list to string. You can find many examples (like this) over the web.
