c# – 使用goto的最佳实践

return ExecuteReader(cmd,reader =>
{
    List<BEPartnership> partnerhip = null;

    //Partnership
    if (!((SqlDataReader) reader).HasRows)
        goto exit;

    partnerhip = 
        new List<BEPartnership>{new BEPartnership().GetFromReader(reader)};

    //Customers
    if (!reader.NextResult() && !((SqlDataReader) reader).HasRows)
        goto exit;

    foreach (BEPartnership p in partnerhip)
        p.Partner = new BECustomer().GetFromReader(reader);

    //Contracts
    if (!reader.NextResult() && !((SqlDataReader) reader).HasRows)
        goto exit;

    List<BEContractB2B> contracts = new List<BEContractB2B>();
    contracts.Add(new BEContractB2B().GetFromReader(reader));
    // contracts = new BEContractB2B().GetFromReader2(reader).ToList();

    exit:
    return partnerhip;
});
