How to use IN with Dapper

I am not sure if this is correct or not. Is there a better way to do this:

public List<Category> ManyCategories(IEnumerable<int> cats)
{
     string categoriesJoined = string.Join(",", cats);
     using (var conn = new SqlConnection())
     {
          conn.Open();

          //make this a union all
          return _categories = conn.Query<Category>("select Id, ParentId, Name from [Meshplex].[dbo].Category where Id IN (@joined)", new { joined = categoriesJoined }).ToList();
      }
}
