Question

我已经找了很多解决方案来解决我的问题，但我没有发现任何对我有益的事情。

我的问题很简单：我无法通过webservice发送一长串字节。我可以发送一个代表4 Kbytes但不大的图像的数组。

这是客户端配置

    <configuration>
        <system.serviceModel>
            <bindings>
                <basicHttpBinding>
                    <binding name="BasicHttpBinding_ICespitiAVService"                              closeTimeout="02:00:00"
                openTimeout="02:00:00" receiveTimeout="02:00:00" sendTimeout="02:00:00"         maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" >
                        <security mode="None" />
                    </binding>
                </basicHttpBinding>
            </bindings>
            <client>
                <endpoint address="http://localhost:51366/CespitiAVService.svc"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICespitiAVService"
            contract="CespitiAVService.ICespitiAVService" name="BasicHttpBinding_ICespitiAVService"/>
            </client>
        </system.serviceModel>
    </configuration>

这是服务器配置

      <system.serviceModel>
        <bindings>
          <basicHttpBinding>
            <binding name="BasicHttpBinding" maxBufferSize="2147483647"
           maxReceivedMessageSize="2147483647">
              <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
           maxArrayLength="2147483647" maxBytesPerRead="2147483647"
           maxNameTableCharCount="2147483647" />
            </binding>
          </basicHttpBinding>
        </bindings>
          <client />
          <behaviors>
            <serviceBehaviors>
              <behavior name="">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="false" />
                <dataContractSerializer maxItemsInObjectGraph="655360"/>
             </behavior>
            </serviceBehaviors>
          </behaviors>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true"/>
      </system.serviceModel>

我已经阅读了解决方案，其中有人说将阅读器配置也放在客户端配置中，但xml不接受它，说它只接受安全节点。

有人说改变客户端配置中的transfermode会解决问题，但我只能使用缓冲模式，它不接受任何其他内容。

我已经使用了fiddler并且它说程序超出了maxarraylength，因为你可以看到我在web.config中更改了这个值，但是我无法在客户端配置中更改，因为它说的是绑定节点没有readerquotas属性。

尝试在Maximum array length quota之后创建新的配置文件（解决了我的问题）并查看它是否解决了您的问题，因为我认为问题是由于您的配置文件造成的。

我认为您需要在客户端上设置端点行为配置，以设置DataContractSerializer的maxItemsInObjectGraph属性。您还应该将readerQuotas添加到客户端的绑定配置中。这应该有效：

客户端：

<behaviors>
  <endpointBehaviors>
    <behavior name="ICespitiAVService_Behavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </endpointBehaviors>
</behaviors>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_ICespitiAVService" closeTimeout="02:00:00"
      openTimeout="02:00:00" receiveTimeout="02:00:00" sendTimeout="02:00:00"
      maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="32" maxArrayLength="2147483647" />
      <security mode="None" />
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:51366/CespitiAVService.svc"
    binding="basicHttpBinding"
    bindingConfiguration="BasicHttpBinding_ICespitiAVService"
    behaviorConfiguration="ICespitiAVService_Behavior"
    contract="CespitiAVService.ICespitiAVService"
    name="BasicHttpBinding_ICespitiAVService"/>
  </endpoint>
</client>

服务器：

<bindings>
  <binding name="LargeMessages" maxReceivedMessageSize="2147483647">
    <readerQuotas maxArrayLength="2147483647" maxDepth="32" />
  </binding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="ICespitiAVService.Behavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
      <dataContractSerializer maxItemsInObjectGraph="2147483647" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="ICespitiAVService.Behavior" name="ICespitiAVService">
    <endpoint address="" binding="basicHttpBinding"
      contract="CespitiAVService.ICespitiAVService"
      bindingConfiguration="LargeMessages"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:51366/" />
      </baseAddresses>
    </host>
  </service>
</services>
