How to increase file uploading limit in asp.net?

Introduction:

In asp.net by default file upload limit is 4mb. But we can increase the uploading size limit. This can be possible changing setting in webconfig file.

We can restrict size of uploading file limit in webconfig file. Suppose we want to upload file of less than or equal to 20 mb, then we will set:

maxRequestLength="20480"

in httpruntimetag in web config file.

Following Code we will use to incease or restrict file size in Asp.Net applications:

<system.web>         <!-- This will handle requests up to 1024MB (1GB) -->         <httpRuntime maxRequestLength="1048576" timeout="3600" />     </system.web>

In above example we can handle upto 1 gb file uploading size.
