Error handing in asp.net c#

i have a big project in asp.net & c# (not MVC). in whole project i forget to handle throw in each and every try catch block. now the problem is : if any error occur then page shows that error. what i want to do is if any Error occurs and goes to throw i want the page to be redirected to the specific page [user friendly message on that page.].

how can i do this? can i write anything that redirect the error page to other url? is there any way to handle it in IIS?

You can set some properties in the Web.config file to handle uncaught errors

<customErrors mode="RemoteOnly" redirectMode="ResponseRewrite" defaultRedirect="/errors/error">
    <error statusCode="404" redirect="/errors/error404" />
    <error statusCode="500" redirect="/errors/error500" />
</customErrors>

The above setup loads the /errors/error page, but you can set a different page for a different error.

Further more, if you want to handle all uncaught errors, e.g. for logging purposes, you can put this code in your Global.asax file. 

public void Application_Error(object sender, EventArgs e)
{
    Exception ex = Server.GetLastError();
    // Do something with ex
}
