c# - Aggregate/Sum Uppercase Case Sensitive Issue -


i have following code use aggregate , sums. problem have source data populates account# column upper , lower case.

i need aggregate/sum regardless of case.

i have tried case insensitive dont seem have got work.

i thinking maybe need clone account# column , make uppercase use clone, unsure how make column uppercase.

please tell me how make code aggregate/sum regardless of case.

thanks

var accountgroups = completedt_svc_ro_dr.asenumerable()     .groupby(x => new {          accno = x.field<string>("account#"),          description = x.field<string>("d e s c r p t o n . . . . . . . . . . . . x")                       .tostring()      })     .select(grp => new {          account = grp.key.accno,          descrpt = grp.key.description,          count = grp.sum(row => row.field<int>("cur-balance...."))      });  var completedt_svc_ro_dr_cr = new datatable(); completedt_svc_ro_dr_cr.columns.add("d e s c r p t o n . . . . . . . . . . . ."); completedt_svc_ro_dr_cr.columns.add("account#"); completedt_svc_ro_dr_cr.columns.add("cur-balance...."); foreach (var grp in accountgroups)     completedt_svc_ro_dr_cr.rows.add(grp.descrpt, grp.account, grp.count);

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 ...
