Asp.net中，上传文件的默认大小是4096 KB，也就是4M，不过你可以在Web.config中更改这个数据
<httpRuntime maxRequestLength="10240"
useFullyQualifiedRedirectUrl="true"
executionTimeout="100"/>
那么此时就是10M的文件，当然你也可以把它修改的更大，但是不管改成多大都会有个极限，如果用户上传的文件比这个值大，就会出现程序Catch不到的异常，因为这个是在运行时才能够监测，如下的错误：
|
Action canceled |

Internet Explorer was unable to link to the Web page you requested. The page might be temporarily unavailable. |

Please try the following:
- Click the Refresh button, or try again later.
- If you have visited this page previously and you want to view what has been stored on your computer, click File, and then click Work Offline.
- For information about offline browsing with Internet Explorer, click the Help menu, and then click Contents and Index.

虽然你在代码中控制了大小，不过程序在运行到这里之前已经崩溃了
// Attachment size is too larger
if(PersonPhoto.PostedFile.ContentLength > 10240)
{
this.lblError.Text = "The file you selected is larger than 10MB";
this.lblError.Visible = true;
return;
}
大家有什么办法嘛？
