我正在编写一个小型WCF / WPF应用程序来调整图像大小,但当我尝试从客户端向我的服务发送大小为28K的图像时,WCF让我感到悲伤。当我发送较小的图像时,该服务工作正常。我立即认为这是一个配置问题,我在网上搜索了关于绑定配置中MaxArrayLength属性的帖子。我已将客户端和服务器上这些设置的限制提高到最大值2147483647,但仍然出现以下错误:
格式化程序在尝试反序列化消息时抛出异常:尝试反序列化时出错 参数http://mywebsite.com/services/servicecontracts/2009/01:OriginalImage。 InnerException消息是'反序列化System.Drawing.Image类型的对象时出错。 读取XML数据时已超出最大数组长度配额(16384)。可以通过更改创建XML阅读器时使用的XmlDictionaryReaderQuotas对象上的MaxArrayLength属性来增加此配额。有关详细信息,请参阅InnerException。
我使我的客户端和服务器配置相同,它们如下所示: 服务器:
<system.serviceModel>

<netTcpBinding>

我的客户端配置如下:

name="NetTcpBinding_ImageResizerServiceContract">
<identity>
<userPrincipalName value="me@domain.com" />
</identity>
</endpoint>
</client>
</system.serviceModel>
似乎无论我将这些值设置为什么,我仍然会收到错误,说wcf无法序列化我的文件,因为它大于16384.有什么想法吗?

我的错 - 我忘了在我的服务器端配置中将绑定配置应用到我的端点。服务器配置应为:
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="NetTcpBinding_ImageResizerServiceContract" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions"
hostNameComparisonMode="StrongWildcard" listenBacklog="10"
maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="10"
maxReceivedMessageSize="2147483647">
<readerQuotas maxDepth="2147483647"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
<reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" />
<security mode="Transport">
<transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" />
<message clientCredentialType="Windows" />
</security>
</binding>
</netTcpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="false" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service name="LogoResizer.WCF.ServiceTypes.ImageResizerService" behaviorConfiguration="ServiceBehavior">
<host>
<baseAddresses>
<add baseAddress="http://localhost:900/mex/"/>
<add baseAddress="net.tcp://localhost:9000/" />
</baseAddresses>
</host>
<endpoint bindingConfiguration="NetTcpBinding_ImageResizerServiceContract" binding="netTcpBinding" contract="LogoResizer.WCF.ServiceContracts.IImageResizerService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
</system.serviceModel>
请注意,bindingConfiguration =“NetTcpBinding_ImageResizerServiceContract”已添加到netTcp端点。我的应用现在适用于更大的图像。甜。

请在绑定中添加<readerQuotas>
。
这是上传和下载byte []时的主要问题,它解决了我的问题。
<basicHttpBinding>
<binding name="ServicesBinding" transferMode="Streamed" maxBufferSize="200000000"
maxReceivedMessageSize="200000000" messageEncoding="Text"
receiveTimeout="00:10:00">
<readerQuotas maxDepth="2147483647"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
</binding>
</basicHttpBinding>

我使用了Microsoft SDK SvcConfigEditor。如果您使用Visual Studio(具有自己的版本),则可以使用此选项。它也是免费下载。
在硬盘上(检查程序文件和程序文件(x86)):
C:\ Program Files(x86)\ Microsoft SDKs \ Windows \ v7.0A \ Bin \ NETFX 4.0 工具\ SvcConfigEditor.exe
C:\ Program Files \ Microsoft SDKs \ Windows \ v7.1 \ Bin \ NETFX 4.0 工具\ SvcConfigEditor.exe
如果您安装了多个Microsoft SDK,那么您使用的版本取决于您正在开发的.NET版本。该工具将抛出一个错误,让您知道您尝试在错误的版本下打开.dll文件。
要使用该工具,请指向服务的.dll文件,让工具完成繁重的工作。如果您有与服务(代理服务)交谈的服务,这将特别有用。另外,请记住,您可能需要为客户端(在应用程序中)和服务器配置(在Web服务上)配置设置。
我在服务器端端点缺少配置。我不得不做两件事:
此外,ASP.NET对此值很挑剔,因此您可以尝试简化配置绑定并将其关闭:
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />

它工作,以前在浏览wcf服务时显示net.tcp://myservice.com/Ac_Service.svc/mex的参考但是现在它是 http://myservice.com/Ac_Service.svc?wsdl
将来也会有用,没有任何问题。
