Maximum file upload question

In ASP.Net (VS 2005), is there a way to limit the user to upload a
file up to certain size (say, I would like to limit the user to upload
at the maximum 1 meg of file) ?
Thank you

Since there is no way for you to tell from the server-side how big the user's
file is, you simply check the UploadedFile object's size at the server and
reject it with the appropriate message to the user.

I suppose Peter was talking about HttpPostedFile.ContentLength property :)

re:

Iy's very simple...

In web.config :

<httpRuntime maxRequestLength="1024"/>

There isn't any way to do that, but you can limit the maximum size for any uploaded file.
See my just-sent-in tip.

It should be noted that this entry will limit the size of all HTTP requests
for all pages controlled by that web.config. You can, however, put the
"upload file" page in its own sub-folder and put a web.config in that folder
with the appropriate settings. For example, you might also want to adjust
the timeout value to allow for slow uploads, etc.

I guess my point is, the upload settings for files is probably different
than for "regular" requests, so consider putting pages that upload files
into their own sub-folder with their own web.config.

Hmmm... a bit nitpicky, but true.

I say nitpicky because I've been trying to figure out what an http request larger than
1MB looks like, other than an uploaded file...and can't come up with a valid example.

However, for comprehensiveness sake, ( just in case a request is made which isn't
an uploaded file but is larger than 1MB ) the following web.config entry would cover all bases :

<configuration>
<location path="UploadPage.aspx">
<httpRuntime maxRequestLength="1024"/>
</location>
</configuration>

Notice that the entry can be located in the root web.config.
A separate web.config is not needed.

If the upload aspx is in a different directory, including the path will do fine :

<location path="/directory/UploadPage.aspx">
