我知道这个问题已经被问过很多次了,相信我,半个下午我一直在查看并尝试其中的许多问题,但仍然无法解决这个问题。
我正在尝试通过 Web 服务提交一些表单内容(也可以包括附件),但是当我尝试附加除小文件以外的任何内容时,总是出现以下错误。
我的完整错误是:
The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:scChildForm. The InnerException message was 'There was an error deserializing the object of type MashForms.Models.SCChildrenForm. The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 41713.'. Please see InnerException for more details.
无论我如何尝试在 WCF 服务和 Web 客户端的 web.config 中重写该值,它仍将其报告为最大值和随后的错误。

我的 WCF 服务将接受非常小的文件,但不能接受更大的文件,甚至不能接受 28k。
作为附加说明,当我最初将服务引用添加到 WebClient 中时,它并没有默认为较大的值,它是这样创建的:

但是我还是有同样的错误。
最佳答案
感谢所有建议。不幸的是,这些建议都没有解决这个问题,它似乎仍然从某个地方获取了一个覆盖它的值。
我已经通过 customBinding 路线成功地处理了更大的文件。

关于c# - WCF:读取 XML 数据时已超出最大数组长度配额 (16384),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/13937555/
我正在寻找执行以下操作的正确语法(在Perl、Shell或Ruby中):#variabletoaccessthedatalinesappendedasafileEND_OF_SCRIPT_MARKERrawdatastartshereanditcontinues. 最佳答案 Perl用__DATA__做这个:#!/usr/bin/perlusestrict;usewarnings;while(){print;}__DATA__Texttoprintgoeshere 关于ruby-如何将脚
我主要使用Ruby来执行此操作,但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式,例如使用这个yaml文件,它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i
我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据,就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理?我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题;这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML,但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中,将我的XML代码修改为
好的,所以我的目标是轻松地将一些数据保存到磁盘以备后用。您如何简单地写入然后读取一个对象?所以如果我有一个简单的类classCattr_accessor:a,:bdefinitialize(a,b)@a,@b=a,bendend所以如果我从中非常快地制作一个objobj=C.new("foo","bar")#justgaveitsomerandomvalues然后我可以把它变成一个kindaidstring=obj.to_s#whichreturns""我终于可以将此字符串打印到文件或其他内容中。我的问题是,我该如何再次将这个id变回一个对象?我知道我可以自己挑选信息并制作一个接受该信
有时我需要处理键/值数据。我不喜欢使用数组,因为它们在大小上没有限制(很容易不小心添加超过2个项目,而且您最终需要稍后验证大小)。此外,0和1的索引变成了魔数(MagicNumber),并且在传达含义方面做得很差(“当我说0时,我的意思是head...”)。散列也不合适,因为可能会不小心添加额外的条目。我写了下面的类来解决这个问题:classPairattr_accessor:head,:taildefinitialize(h,t)@head,@tail=h,tendend它工作得很好并且解决了问题,但我很想知道:Ruby标准库是否已经带有这样一个类? 最佳
如何在ruby中调用C#dll? 最佳答案 我能想到几种可能性:为您的DLL编写(或找人编写)一个COM包装器,如果它还没有,则使用Ruby的WIN32OLE库来调用它;看看RubyCLR,其中一位作者是JohnLam,他继续在Microsoft从事IronRuby方面的工作。(估计不会再维护了,可能不支持.Net2.0以上的版本);正如其他地方已经提到的,看看使用IronRuby,如果这是您的技术选择。有一个主题是here.请注意,最后一篇文章实际上来自JohnLam(看起来像是2009年3月),他似乎很自在地断言RubyCL
