angularjs - How to change order of the menu items of the modules into mean.io? -

-
i had added each module of application menu of mean.io, of app.js file this: theme.menus.add({ title: 'theme example page', link: 'theme example page', roles: ['authenticated'], menu: 'main' }); all modules shown in menu, order wrong, how can change order? you need specify order of menu adding. for example: function menuconfig(menus) { menus.addmenuitem('topbar', { title: 'cuentas', state: 'accounts', type: 'dropdown', roles: ['*'], position: 1 }); } you need use attribute >> position. position (optional; default: 0) - specify order of appearance.

c# - WebApi - Convert null string into null value -

-
what best way convert 'null' string (passed url) null value in webapi using attribute routing? url sample: localhost:29365/api/mycontroller/test/first/null/third api controller method sample: [httpget] [route("~/api/mycontroller/test/{first}/{second}/{third}")] public void test(string first, string second, string third) { ... } well option comparing if string value null. seems terrible. why not try passing parameters instead. [httpget] [route("~/api/mycontroller/test")] public void test(string first = null, string second = null, string third = null) { ... } url sample localhost:29365/api/mycontroller/test?first=myfirstvalue&third=mythirdvalue by not supplying second value null default.
