How to insert DateTime2

What is the appropriate way to insert a value into a column of type DATETIME2(7) into SQL Server using a SqlCommand?

Here is what I tried:

DateTime d = new DateTime(2000, 1, 1, 0, 0, 0).AddTicks(1111111);

using (SqlCommand cmd = conn.CreateCommand()) {
    cmd.CommandText = "INSERT DtTest VALUES(@d)";
    cmd.Parameters.AddWithValue("@d", d);
    cmd.ExecuteNonQuery();
}

But when I check the database for the value, I get:

2000-01-01 00:00:00.1100000

Which is the value rounded to DATETIME precision.

What do I have to do to get the precise value including the last five digits?

You can specify the column type like this:

var sql_parameter = new SqlParameter("@d", SqlDbType.DateTime2);
sql_parameter.Value = d;
cmd.Parameters.Add(sql_parameter);

Or more succinctly:

cmd.Parameters.Add( "@d", SqlDbType.DateTime2 ).Value = d;
