------解决方案--------------------
是不是系统限制上传4M文件的选项没打开啊
------解决方案--------------------
有可能


<configuration>
<system.web>
<httpRuntime maxRequestLength="32768" />
</system.web>
</configuration>

maxRequestLength: Optional Int32 attribute.
Specifies the limit for the input stream buffering threshold, in KB. This limit can be used to prevent denial of service attacks that are caused, for example, by users posting large files to the server.
The default is 4096 (4 MB).
