UploadFile file = AspnetUpload.GetUploadFile("file1"); 这句话。。断点运行的时候。。文件上传获取不到值。。file始终是null

[周公]

问题出在哪里？
错误原因或者异常描述说一下嘛。

[lwh314375546]

An exception of type 'System.NullReferenceException' occurred in AiLiKe_App.DLL but was not handled in user code

Additional information: Object reference not set to an instance of an object.

报的是这个错。。断点的时候
UploadFile file = AspnetUpload.GetUploadFile("file1"); 这句话。。断点运行的时候。。文件上传获取不到值。。file始终是null
