Here is my technique I'd like to share. Works well so long as your clr property types are sql equivalent types eg. bool -> bit, long -> bigint, string -> nchar/char/varchar/nvarchar, decimal -> money

public void SaveTransaction(Transaction transaction) 
{
    using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConString"].ConnectionString))
    {
        using (var cmd = new SqlCommand("spAddTransaction", con))
        {
            cmd.CommandType = CommandType.StoredProcedure;
            foreach (var prop in transaction.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
                cmd.Parameters.AddWithValue("@" + prop.Name, prop.GetValue(transaction, null));
            con.Open();
            cmd.ExecuteNonQuery();
        }
    }
}
