Uploading Large File to IIS/ ASP.NET

When we upload a large file in asp.net using file upload control we got a error.so how to over come this ? The Default size of Asp.Net is 4MB.

 

Code 

 

In Web.Config put this code.

<system.web>
   <httpRuntime maxRequestLength="1048576" executionTimeout="600" />
</system.web>
<system.webServer>
   <security>
      <requestFiltering><requestLimits maxAllowedContentLength="3000000000" /></requestFiltering>
   </security>
</system.webServer>

The below code maxRequestLength measured in kilobytes.Here is an example with a 1GB request length and a 10 minute request timeout:

<httpRuntime maxRequestLength="1048576" executionTimeout="600" />

 The below code maxAllowedContentLength measured in bytes. 

<requestLimits maxAllowedContentLength="3000000000" />
