当我搜索1天数据时,我正在使用Wcf我得到了结果,但如果我搜索30天数据,我会收到以下错误.

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.

我的Service.config文件具有以下代码.

解决方法

也许问题与消息的总大小无关,而与消息元素的大小无关.

看看这个问题：
WCF maxReceivedMessagesize and readerquotas

如果这是问题,请添加以下配置：

<binding name="BasicHttpBinding_ToursGdsService" >
      <textMessageEncoding messageVersion="Soap12" />
      <httpTransport  maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647"  maxBufferSize="2147483647"/>
       <readerQuotas
          maxDepth="2147483647"
          maxStringContentLength="2147483647"
          maxArrayLength="2147483647"
          maxBytesPerRead="2147483647"
          maxNameTableCharCount="2147483647" />
    </binding>

此外,您可以尝试在绑定而不是httpTransport上添加属性maxReceivedMessageSize,maxBufferPoolSize和maxBufferSize.
