C# get csv variables to JSON String -


i wrote code read out data csv file , save important values each line string convert json. though still new c# , didn't use json related don't know how best way.

here code have far:

using system; using system.io; using system.collections.generic;  namespace csv_importer {     class program     {         static void main(string[] args)         {             // read file , display line line.               string medicaldata;             filestream medicalfile = new filestream(@"c:\csv health-care cs\csvexport_01_03_2017.csv", filemode.open);             streamreader medicalfilereader = new streamreader(medicalfile);              list<participant>list = new list<participant>();              medicaldata = medicalfilereader.readline();              while ((medicaldata = medicalfilereader.readline()) != null)             {                 //medicaldata = medicalfilereader.readline();                 //console.writeline(medicaldata);                  string[] medicaldataarray = medicaldata.split(';');                  participant participanttemp = new participant();                 participanttemp.dateofbirth = medicaldataarray[0];                 participanttemp.gender = medicaldataarray[1];                 participanttemp.bmivalue = convert.todouble(medicaldataarray[9]);                 participanttemp.relativefatmass = convert.todouble(medicaldataarray[12]);                 participanttemp.absolutefatmass = convert.todouble(medicaldataarray[13]);                 participanttemp.fatfreemassvalue = convert.todouble(medicaldataarray[14]);                 participanttemp.skeletalmusclemassvalue = convert.todouble(medicaldataarray[15]);

                participanttemp.restingenergyexpenditurevalue = convert.todouble(medicaldataarray[302]);                 participanttemp.ffmivalue = convert.todouble(medicaldataarray[307]);                 participanttemp.fmivalue = convert.todouble(medicaldataarray[308]);

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 ...
