我创建了一个 WCF 服务来上传图像。它适用于各种小图像。但是当我尝试使用 800KB 之类的图像时，我得到“远程服务器返回错误：（400）错误请求。” 当我查看日志文件时，我看到了这个异常： ThrowMaxReceivedMessageSizeExceeded() 我一直在寻找年龄并尝试了很多不同的东西，包括设置 maxRequestLength 和其他几个设置。

我有 WCFApp、WebApplocation-用于我的站点，以及 classLibrary-用于具有服务参考的 BLClient。

这些是我的配置文件：

WCFApplication 的 Web.config：

 <?xml version="1.0"?>
     <configuration>
  <connectionStrings>
    <add name="photoShopEntities"
         connectionString="metadata=res://*/photoShop.csdl|

         res://*/photoShop.msl;
         provider=System.Data.SqlClient;provider connection string='Data Source=.\SQLEXPRESS;AttachDbFileName=|DataDirectory|photoShop.mdf;Integrated Security=True;User Instance=True'"
         providerName="System.Data.EntityClient" />
  </connectionStrings>

          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>

我看到了很多关于它的答案，但我的问题仍然存在。任何帮助是极大的赞赏！

在 WCF 应用程序的 web.config 中，您必须将其指定maxReceivedMessageSize为更高的值。

前任。

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
             <binding transferMode="Streamed"
                     maxReceivedMessageSize="67108864">
               <!-- other config here -->
            </binding>
        </basicHttpBinding>
    </bindings>
</system.serviceModel>

我使用了标记帮助，现在我的网站允许上传大图像。

这是更改后我的 WCFApplication 的 web.config。

<?xml version="1.0"?>
<configuration>
  <connectionStrings>
    <add name="photoShopEntities"
         connectionString="metadata=res://*/photoShop.csdl|
         res://*/photoShop.ssdl|
         res://*/photoShop.msl;
         provider=System.Data.SqlClient;provider connection string='Data Source=.\SQLEXPRESS;AttachDbFileName=|DataDirectory|photoShop.mdf;Integrated Security=True;User Instance=True'"
         providerName="System.Data.EntityClient" />
  </connectionStrings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
    <httpRuntime maxRequestLength="2147483647"/>
  </system.web>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding transferMode="Streamed"
                maxReceivedMessageSize="67108864">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647"
            maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <!-- other config here -->
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior>

          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

非常感谢！！

如果它存在于 httpTransport 元素中，则在 classLibrary 的 App.config 中：

maxReceivedMessageSize="104857600"
