c# - How to get rid of properties not belonging to the class? -


this question has answer here:

say have these 2 classes

class car {   public string carname {get;set;} }  class employeecar:car {   public string employeename {get;set;} }

when call api

[httpget] public car getcar(employee employee) {   return getemployeecar(employee); }

assuming

private employeecar getempoyeecar(employee employee) {      return new employeecar { carname: "car 1", employeename: "employee 1" }; }

i getting this

{ carname: "car 1", employeename: "employee 1" }

note employeename not belong car.

how can api return properties of car? (which return type of api) ie.

{ carname: 'car 1' }

solution

this longer hoped (not sure if there shorter version) hope can someone

public car getcar(employee employee) {     car cardirty = getemployeecar(employee); // { carname: "car 1", employeename: "employee 1" }      car carclean = sweepforeignproperties(cardirty); // keep properties of car      return carclean; // { carname: "car 1" } }  /// <summary>only keep t's own properties, getting rid of unknown/foreign properties may have come child class</summary> public static t sweepforeignproperties<t>(t dirty) t: new() {     t clean = new t();     foreach (var prop in clean.gettype().getproperties())     {         if (prop.canwrite)             prop.setvalue(clean, dirty.gettype().getproperty(prop.name).getvalue(dirty), null);     }     return clean; }

if using newtonsoft json, can add jsonignore attribute causes marked property being serialized/deserialized

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
