WCF超时
参照网上的例子做的个异步上传，上传单个300M文件没问题，开了4个一起上传就报错了，但是上传几M那种4个一起开就不出错，不知道为什么，感觉同时传多个一到某个时间（2分钟左右）就报错，小文件是时间短没报出来，4个一起上传的时候，调
试页面会出个错误（服务器连接超时），但是不停止调试这些文件都能完整上传，只是页面早就报错了，也就是说页面报错没
影响到上传。到底是配置问题还是上传代码的问题，高手指点下，小弟新手，在线等，配置文件如下：

这里面的前面是max的数据后面都加几个0试试。 --------------------编程问答-------------------- 原来觉得是你客户端没有及时关闭导致的。
但看你配置：
<serviceThrottling maxConcurrentCalls="100" maxConcurrentInstances="100" maxConcurrentSessions="100"/>
都是100厄。。。按楼上的方法改改看把。
btw: 开了4个一起上传就报错了，但是上传几M那种4个一起开就不出错 什么意思？
4个一起上传和4个一个开什么区别？ --------------------编程问答-------------------- 属于并发吗？
--------------------编程问答--------------------
改了，没用，继续测了是上传到385M出的问题，我意思是我上传几M那种，开了4个客户端一起上传就没事，如果是1 200M的就出错了
--------------------编程问答--------------------
我想做并发，但是参考的这个例子也没觉得哪里体现了并发，我开几个客户端同时上传，服务器都开始接收，这样算实现并发不？
--------------------编程问答--------------------
现在发现不管是并发还是单个传，只要这次上传量达到385M就出错，但是我客户端和服务端的配置文件把里面的值都改最大了，还是出错服务端：

</system.serviceModel> --------------------编程问答-------------------- 我自己测试了下。上传个2G的东东没有问题。不过我是用WinformHost的。不知道是不是IIS Host的问题？
<system.web>配置节下的<httpRuntime maxRequestLength="2097151" /> 有设置吗？ --------------------编程问答-------------------- --------------------编程问答--------------------
--------------------编程问答-------------------- 如果WCF以IIS作为宿主，WCF传输数据量的能力受HttpRunttime MaxRequestLength属性的制约，HttpRunttime MaxRequestLength 设置请求的最大大小（以千字节为单位）。默认大小为 4096 KB (4 MB)，允许的最大值是2097151。 --------------------编程问答-------------------- remark,明天试一下
<endpoint address="" binding="wsHttpBinding" contract="" />
设置下最大上传大小
补充：.NET技术 , .NET Framework
