错误原因：这个错误的引起是因为应用程序最大请求字节长度超过了默认请求字节长度

解决方案：可以在Web.Config添加如下配置：

<system.web>下面加上下面一句.搞定.
  <httpRuntime executionTimeout="300" maxRequestLength="51200"/>

 

或加如下一段也可解决.

  <httpRuntime
   executionTimeout="1200"
   maxRequestLength="102400"
   useFullyQualifiedRedirectUrl="false"
   minFreeThreads="8"
   minLocalRequestFreeThreads="4"
   appRequestQueueLimit="100"
