上下文：C#、Xero.Api

我在 Invoices 上度过了一段有趣的时光。我编写了一些 C# 代码来接受来自命令行的查询字符串和文件名。我对 Xero 的端点运行查询并将结果存储在文件中。到目前为止，一切都很好。

但是，我发现在某些情况下会出现异常结果。

我正在使用以下 C# 代码：

    private static void Main(string[] args)
    {
        if (args.Length != 2)
        {
            Console.WriteLine("Syntax:\n\tXero \"<querystring>\" <outputspec>");
            Environment.Exit(1);
        }
        var query = args[0];
        var fspec = args[1];

        Console.WriteLine($"{query}\n{fspec}");

        // Private Application Sample
        var xeroCoreApi = new XeroCoreApi("https://api.xero.com",
            new PrivateAuthenticator(<not shown>),
            new Consumer(<not shown>, <not shown>),
            null,
            new DefaultMapper(),
            new DefaultMapper());

        var org = xeroCoreApi.Organisation;

        var user = new ApiUser { Name = Environment.MachineName };

        var invoices = xeroCoreApi
            .Invoices
            .Where(query)
            .Find();

        var total = invoices.Count();
        var page = 2;

        StringBuilder sb = new StringBuilder();
        sb.Append("<Invoices>");
        if (invoices.Any())
        {
            foreach (Invoice I in invoices)
            {
                GatherInvoiceDetails(sb, I);
            }
            total = invoices.Count();

            while (invoices.Count() == 100)
            {
                invoices = xeroCoreApi.Invoices.Page(page++).Find();
                if (invoices.Any())
                {
                    total += invoices.Count();
                    foreach (Invoice I in invoices)
                    {
                        GatherInvoiceDetails(sb, I);
                    }
                }
            }
        }
        sb.AppendLine("</Invoices>");
        Console.WriteLine($"pages: {page-1}. invoices: {total}");
        System.IO.File.WriteAllText(fspec, sb.ToString());
    }

我有一个包含以下内容的批处理文件：

@echo off
Xero.exe "DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == ""AUTHORISED""" \temp\authorised.xml 
Xero.exe "DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == ""DELETED""" \temp\deleted.xml 
Xero.exe "DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == ""DRAFT""" \temp\draft.xml 
Xero.exe "DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == ""PAID""" \temp\paid.xml 
Xero.exe "DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == ""VOIDED""" \temp\voided.xml 
Xero.exe "DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14)" \temp\all.xml

运行批处理给出：

DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == "AUTHORISED"
\temp\authorised.xml
pages: 1. invoices: 32
DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == "DELETED"
\temp\deleted.xml
pages: 1. invoices: 0
DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == "DRAFT"
\temp\draft.xml
pages: 1. invoices: 2
DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == "PAID"
\temp\paid.xml
pages: 34. invoices: 3339
DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14) && Status == "VOIDED"
\temp\voided.xml
pages: 1. invoices: 26
DueDate >= DateTime(2017,08, 01) && DueDate <= DateTime(2017,09, 14)
\temp\all.xml
pages: 34. invoices: 3339

请注意，“all.xml”输出存储了 3339 张发票。“paid.xml”还存储了 3339 张发票。如果您进行算术运算，您会注意到作废、付款、草稿、删除和授权的数字加起来大于 3339。

这有点奇怪。有任何想法吗？

附言

这也很奇怪，在 all.xml 中，有一些项目的 DueDate 超出了请求的范围，例如

<DueDate>7/22/2016 12:00:00 AM</DueDate>

也许我只需要绕过 Xero 过滤并自己做，即

        var everything = new System.Collections.Generic.List<Xero.Api.Core.Model.Invoice>();

...

            foreach (Invoice I in invoices)
            {
                everything.Add(I);
            }

...

        IEnumerable<Invoice> some = everything
            .Where(i => i.DueDate >= new DateTime(2017, 08, 01) 
            && i.DueDate < new DateTime(2017, 09, 13) 
            && i.Status == Api.Core.Model.Status.InvoiceStatus.Paid);
