WCF 16384 最大数组长度

Question

试图解决这个问题一天。我看不到我的代码有任何错误，请帮忙。谢谢！ 我正在使用 IIS 来托管服务并为客户端使用添加服务引用。 我确保我添加了 readerquota 和正确的绑定配置。尽管如此，当我发送大小超过 16384kb 的图像文件时仍会发生错误。

在我将服务器和客户端更新为正确的值和正确的绑定后，我已经解决了这个问题。我的客户端仍在发送默认配置。此外，configuration.svcinfo 文件仍为默认值且未更新。有什么想法吗？

Answer 1

您是否更改了服务器端和客户端的配额配置。

Answer 2

首先，您确定您已将 HttpRuntime 设置为超过 4MB。如下图所示：

<httpRuntime maxRequestLength="1572864"/>

上述元素位于 system.web 元素下。 .NET 框架的 http 运行时默认不允许超过 4MB 的数据。

您在服务器和客户端上的读者配额有点不同。确保您的客户端阅读器配额与服务器的相同。

完成上述操作后，您仍然遇到问题，然后尝试在您的服务上启用跟踪，它应该会告诉您请求失败的确切原因。要启用跟踪，请按照文章here

Answer 3

客户端还应该获得一个设置 maxItemsInObjectGraph 的 behaviorConfiguration

<system.serviceModel>
  <behaviors>
    <endpointBehaviors>
      <behavior name="ServiceBehavior">
        <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
      </behavior>
    </endpointBehaviors>
  </behaviors>

然后.. 在您的客户端端点上引用这个新行为...

<endpoint address="http://youraddresshere"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService"
            contract="" name="" behaviorConfiguration="ServiceBehavior" />

您也可以尝试在您的客户端和服务设置中增加您的 maxBytesPerRead="" 值。
