请求实体WCF过大问题

Question

我有一个简单的WCF，它有两个方法，第一个是：GetDetails，这个方法，在字节数组中给我返回一些信息和一些图像（所有这些都在XML文档中），但我遇到了一个问题：

当我尝试调用这个方法时：

using (testWCF wcfClient = new testWCF()) { //new testWCF() has no parameter costructors, so i can't use bindings or different endpoint...Why?...anyway
                string ff = wcfClient.GetDetails ("Test");
            }

调试器抛出一个新的异常：（413）请求实体太大

这很奇怪，因为在web.config中，配置似乎很好：

<?xml version="1.0"?>
<configuration>
  <appSettings/>
  <system.web>
    <compilation targetFramework="4.0"/>
    <membership defaultProvider="ClientAuthenticationMembershipProvider">

求你了，帮帮我，我在这上面挣扎。

谢谢。

更改您的配置如下：

1. 您必须增加UploadReadAheadSize。（默认大小48kb）

2. 将最大接收消息大小增加到以下

   <basicHttpBinding>
     <binding maxReceivedMessageSize="10485760">
     </binding>
   </basicHttpBinding>
