can use mvc routing limit page number? want someting this:

routes.maproute(   name: "limitpaging",   url: "*/page-{pagenumber}",   defaults: new { controller = "error", action = "p404", },              new { pagenumber = @"\d+" },              new { pagenumber > 200 } );

thanks

your create custom route constraint (a class implements irouteconstraint)

public class lessthanpage : irouteconstraint {   private int _maxpage;    public lessthanpage(int maxpage)   {     _maxpage = maxpage;   }    public bool match(httpcontextbase httpcontext, route route, string parametername, routevaluedictionary values, routedirection routedirection)   {     return convert.toint32(values[parametername].tostring()) <= _maxpage;   } }  routes.maproute(   name: "limitpaging",   url: "*/page-{pagenumber}",   defaults: new { controller = "error", action = "p404", },    constraints: new { pagenumber > new lessthanpage(200) } );

you use method validate parameter number , therefore delete regular expression constraint
