发送大量数据，WCF服务

问题描述：

我想自定义数据从客户端应用程序发送到WCF网站。当我尝试发送大量数据时，它不起作用。

失败的指令是：

roleCliente.SaveStructure(role, ref s);

“角色” 包含自定义对象的列表;该指令在列表足够短时正确工作。

服务器端的web.config是：

<configuration> 

    <system.web> 
    <compilation debug="true" targetFramework="4.0"/> 
    <httpRuntime maxQueryStringLength="2097151"/>

_ “它不工作” _是不是一个错误。什么是确切的例外信息，你尝试过什么？ – CodeCaster

我很好奇，当你的意思很大，那有多大？ –

我解决了在“basicHttpBinding”下添加一个未命名的绑定。有人解释我为什么吗？ – user1047400

答

如果你想发送在WCF中，你可能会使用大量的数据流式模式。

http://msdn.microsoft.com/en-us/library/ms731913.aspx

http://msdn.microsoft.com/en-us/library/ms733742.aspx

或者你可以使用的解决方法，并通过实现服务的几种方法传输数据以块的形式，像

StartUpload() 

SendChunk(byte[] chunk) 

EndUpload()

答

还有就是，如果你决定真的两个选项将消息大块分组，以便简单地增加最大配额或超时值。

选项1：大块它自己

选项2：通道分块 http://msdn.microsoft.com/en-us/library/aa717050(v=vs.110).aspx
