using (SqlBulkCopy bcp = new SqlBulkCopy(csDest))
{
    bcp.DestinationTableName = "SomeTable";
    cmd.CommandText = "myproc";
    cmd.CommandType = CommandType.StoredProcedure;
    connSource.Open();
    using(SqlDataReader reader = cmd.ExecuteReader())
    {
        bcp.WriteToServer(reader);
    }
}
