I am working on the demo project for File Upload mechanism in ASP.Net c#.

I tested that demo on my local machine and it is working fine for file with 520 kb file size. But when I try to upload file with 19.20 mb file size, it gives an following error:

Server Error in '/' Application.

Maximum request length exceeded.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Web.HttpException: Maximum request length exceeded.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.1038.0

What I have tried:

I tried to add some line of code in web.config as suggested in some question related to this, which is as follows:

      <requestLimits maxAllowedContentLength="1073741824" />

Add following lines of code in your web.config.

  <httpRuntime maxRequestLength="1073741824" targetFramework="4.5" />

if you are running on IIS 7 or later add following lines.

      <requestLimits maxAllowedContentLength="1073741824" />
Follow instructions given here.
