Hi Sarathlal,

I followed your multipart code for uploading larger files. Its working for me in localhost, but in IIS, i could not upload more than 29 MB file.

I googled and followed all the suggesstions such as:

increased maxAllowedContentLength in RequestFiltering

Added the below line in web.config

But still, I could not upload file which is greater than 30 MB.

Kindly suggest anything...

Hi,

Increase the " httpRuntime executionTimeout="9999" " then try it and after you are facing the same issue then share the error screen shot.

Hi,

When we upload a large file in asp.net using file upload control we got an error because the default size of Asp.Net is 4MB.

The below code maxRequestLength measured in kilobytes.Here is an example with a 1GB request length and a 10 minute request timeout:
<system.web>
<httpRuntime maxRequestLength="1048576" executionTimeout="3600" />
system.web>
<system.webServer>
<security>
<requestFiltering><requestLimits maxAllowedContentLength="3000000000" />requestFiltering>
security>
system.webServer>
