Question

How to programmatically set (using GET SET property) "httpRuntime maxRequestLength" in ASP.NET with C# as code behind

is there any way to set values in web.config through C# ?

Answer 1

You can set the web.config's maxRequestLength property in code like this:

Configuration webConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration( "~" );
var section = (System.Web.Configuration.SystemWebSectionGroup)webConfig.GetSectionGroup("system.web");
section.HttpRuntime.MaxRequestLength = 10 * 1024; // 10 MB
webConfig.Save();

We do this exact thing in our Rock RMS content management system.
