1. if your file is modestly large, modify your web.config<httpRuntime executionTimeout="54000" maxRequestLength="512000" /> 2. 参考http://blog.joycode.com/saucer/archive/2004/03/16/16225.aspx
also seeLarge File Uploading in ASP.NET http://weblogs.asp.net/mhawley/archive/2004/05/11/129824.aspxIn your web.config, add a line under your system.web <httpRuntime executionTimeout="54000" maxRequestLength="512000" /> In your machine.config, modify responseDeadlockInterval to equal the same amount of time for executionTimeout.

《httpRuntime maxRequestLength》设置最大上载限制
上传大小和控件没关系。是web.config里的设置有关系<httpRuntime executionTimeout="54000" maxRequestLength="512000" /> maxRequestLength 可以设置。

老大不会吧，电影也要用这个上传，那你就的保证1、设置<httpRuntime executionTimeout="超时" maxRequestLength="上限K" />
2、设置session的timeout时间足够长；建议传大文件还是用ftp方式比较好
