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="1073741824" executionTimeout="3600" />
</system.web>

<system.webServer>
<security>
<requestFiltering>
<!--修改服务器允许最大长度-->
<requestLimits maxAllowedContentLength="1073741824"/> 
</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
