Uploading file size over 4 MB in .NET

Question

I am having trouble uploading a file size over 4 MB. I've tried adding

<httpRuntime maxRequestLength="102400" executionTimeout="99999" />

to my Web.Config like many posts have suggested, but it just isn't working. Files under 4 MB work just fine, so I'm nearly certain I'm running into the 4 MB limit. Are there any settings in IIS that I might need to change?

We're going to need more information than "having trouble" and "just isn't working". Is this ASP.NET? IIS? — Dour High Arch, Aug 22 '11 at 22:32
If you using IIS7, you might also need to check the "maxAllowedContentLength". I think the default is 28MB, but it's possible this might have been changed... — Zachary, Aug 22 '11 at 22:40
So I found that I had 2 web.config files in my project, and I was writing to the wrong one. — Matt Schaeffer, Aug 23 '11 at 01:46

You need to update the value of maxrequestlength in the web.config:

Maximum value of maxRequestLength?

Oh, sorry about that then. So the question reads incorrectly then? – Philipp Schmid Aug 23 '11 at 17:03
It reads differently than it did when I answered it...but no big deal. I think he was just incorporated what he'd already tried when he updated it. – Chris B. Behrens Aug 23 '11 at 20:04

You can use that code into your web.config file.

<system.web>
<httpRuntime executionTimeout="3600" maxRequestLength="102400000000" 
 appRequestQueueLimit="100000" requestValidationMode="4.0"
 requestLengthDiskThreshold="10024000000000"/>
</system.web>

I think it will work
