How to access httpRuntime section of web.config fr

Question

actually i need the maxRequestLength value of the httpRuntime section in web.config to check if a postedfile's size is greater. What's the best way to read it?

Thank you in advance.

Answer 1

You can try something like

HttpRuntimeSection section = ConfigurationManager.GetSection("system.web/httpRuntime") as HttpRuntimeSection;

you can then get section.MaxRequestLength

Answer 2

On load of your page set the max file size to a client side variable and check it on a client event because if you request the server to check it obviously it will error out before it gets to your validation.
