Question

您好，

我正在尝试从客户端应用程序向WCF网站发送自定义数据。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);

“role”包含自定义对象列表;当列表足够短时，指令正常工作。

服务器端web.config是：

<configuration>

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

Answer 1

如果你想在WCF中发送大量数据，你可能会使用流模式。

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

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

或者您可以通过实现多种服务方法（例如

）来使用变通方法并以块的形式传输数据

StartUpload()

SendChunk(byte[] chunk)

EndUpload()

Answer 2

如果您决定将消息分块，只是增加最大配额或超时，那么确实有两种选择。

选项1：自己分块

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

将大数据发送到WCF服务
