我遇到了这个我正在努力处理的疯狂问题.我知道当我们获取大量数据时,我们必须增加客户端.config文件的配额,但如果我的客户端向WCF服务器发送大量数据,我应该怎么做?
当我发送小尺寸输入参数时,它完全正常.不幸的是,当输入变大时,它会崩溃.
调试器说:
错误请求,400;
在跟踪文件上它是:
已超出传入邮件的最大邮件大小限额(65536).要增加配额,请在相应的绑定元素上使用MaxReceivedMessageSize属性.
是否有某种方法可以增加服务器端的数据配额?如果是这样,怎么样?
这是我的示例配置相关部分:

我正在开发一个项目,可以处理从服务器到客户端的大型文件.我认为WCF流是一个很好的选择,因为它应该允许处理理论上无限的文件大小.我的客户端和服务器都将transportMode(在绑定上)设置为"Streamed",并将消息设计为包含Streams.但是,这还不够,因为我收到一个CommunicationException,表明我需要增加maxReceivedMessageSize属性.遵循异常的建议,神奇地增加属性可以使一切工作完美.
我担心WCF迫使我"限制"我的服务/客户端可以处理多少,即使流媒体应该是"无限的".如果出现的文件恰好大于我的绑定配置,则会发生相同的CommunicationException.我不明白为什么WCF会随意限制我处理大文件的能力,"何时"和"如何"发送和存储这些文件现在是"我的"业务,因为我有一个流消费但我希望.
我错过了什么吗?
我的WCF服务有一个OperationContract,它接受一个对象数组作为参数.这可能非常大.在寻找Bad Request:400的修复程序后,我找到了真正的原因:最大邮件大小.
我知道之前在很多地方已经提出过这个问题.我已经尝试过每个人都说:"增加客户端和服务器配置文件的大小." 我有.它仍然无法正常工作.

我们有一个使用WebServiceHostFactory初始化的Web服务,但是如果它被抛出超过64k,我们会收到'400 Bad Request'.通常情况下,这可以通过提升MaxReceivedMessageSize,MaxBufferSize和MaxBufferPoolSize来解决.问题是使用WebServiceHostFactory,Web.Config被完全忽略.我在ServiceModel部分中所做的任何更改都不会反映在服务中.
完全抛弃WebServiceHostFactory并从头开始设置web.config会很不错,但如果没有它,我们的服务将无法运行.其中一个方法有一个stream参数以及一些其他字符串参数.没有工厂,我们得到
System.InvalidOperationException: For request in operation Test to be a stream the operation must have a single parameter whose type is Stream

所以不能选择拆除工厂.我无法确切地知道工厂正在做什么修复了这个错误,但我花了4天时间就没有了.
我也试过以编程方式覆盖MaxReceivedMessageSize,我在附近发现了一些例子:

{
base.OnOpening();
