貌似这个问题已经被问过千百次了，但是每个人的配置问题都不一样。我有提供图像并接收上传图像请求的 WCF 服务器。上传图片时，当大小超过 65k 时出现错误 400。

我在 WCF 上打开了跟踪，我得到了确切的错误

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

我知道我需要增加这个参数，但我只能在我的 web.config 文件中找到它应该在哪里。这是我在 web.config 中的内容：

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>

        <binding name="BasicHttpBinding_ITransferService" closeTimeout="04:01:00"

这里的任何人都可以帮助我解决这个问题吗？;) 尝试了 4 个小时，在 stackoverflow 上找到了不同的方法，但没有任何帮助 - 不幸的是。

更新：

该请求是从客户端到服务器的文件上传。启用诊断时，错误出现在服务器日志文件中。

代替：

  <system.web>
    <httpRuntime maxRequestLength="2147483647" />
  </system.web>

和

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
    <httpRuntime maxRequestLength="2147483647" />
  </system.web>

允许整体 httpRuntime -> maxRequestLenght 增加；）

祝大家周末愉快

这确实会特别影响 maxReceivedMessageSize 配置，但它可能是客户端或服务器。因为客户端正在接收回复，但服务器正在接收请求。所以这取决于哪个太大。例如，如果客户端发送大负载，但服务器发送回 void 或 bool 或其他小东西，则必须更改服务器的配置，反之亦然。

这可能是客户端的问题。你有没有改变maxReceivedMessageSize，在你maxBufferPoolSize的maxBufferSize客户端？
