check file size before upload

[puja]

hi all,

In asp.net 2.0 there is a limit on file size upload of 4MB. I know this
limit can be increased in web.config file.
Is there any way to check the file size before upload ?
if user is trying to upload file size more than 4MB then just display a
message that file size is too big and can't be uploaded.

thanks

You can find HttpPostedFile object in FileUpload control.

Such as,
HttpPostedFile MyFile;
int FileLen;
System.IO.Stream MyStream;

MyFileCollection = Request.Files;
MyFile = MyFileCollection[0];

FileLen = MyFile.ContentLength;

Now, you can check file length and display some messages to alert user.

Can youplease explain where you have included this code? 'Cos fo all
postback event, the file starts upload before checking the size.

I use ASP.Net version 1.1 and is there any way to check the file size
before uploading (though Javascript)?

Thanks
