C# fileUpload视频上传

要实现大文件上传必须配置webConfig例如：

<system.web>

<compilation debug="true" targetFramework="4.5" />

<!--<httpRuntime targetFramework="4.5" />-->

<httpRuntime targetFramework="4.5" maxRequestLength="" executionTimeout="" />

</system.web>

<system.webServer>

<security>

<requestFiltering>

<!--修改服务器允许最大长度-->

<requestLimits maxAllowedContentLength=""/>

</requestFiltering>

</security>

</system.webServer>

index页面

运用jQuery-file-Upload需要引用以下js

jquery.ui.widget.js
jquery.iframe-transport.js
jquery.fileupload.js
