Dynamic khoom nthuav tawm cov tswv cuab xws li cov khoom thiab cov txheej txheem ntawm lub sijhawm ua haujlwm, tsis yog ntawm lub sijhawm sau. Dynamicobjects kuj muab kev nkag tau yooj yim rau dynamic hom lus xws li IronPython thiab IronRuby. Koj tuaj yeem siv a dynamicobject xa mus rau a dynamic tsab ntawv uas txhais tau lub sijhawm ua haujlwm.
Yog li ntawd, dab tsi yog qhov txawv ntawm cov khoom thiab dynamic?
Feem ntau, ob qho tib si dynamic lo lus tseem ceeb thiab khoom tsis txhob ua compile-time hom checks thiab txheeb xyuas hom khoom ntawm lub sijhawm khiav nkaus xwb thiab ob qho tib si tuaj yeem khaws txhua yam ntawm qhov sib txawv. Cov ntsiab lus hauv qab no txhais Yam khoom thiab Dynamic variables hauv C#. Qhov txawv 1. Yam khoom : Lub Compiler muaj cov ntaub ntawv me me txog hom
Ib tug kuj nug, peb puas tuaj yeem tsim cov khoom dynamic hauv C# thiab DynamicObject yog dab tsi? Piv txwv li, koj tuaj yeem tsim ib qho piv txwv ntawm DynamicObject chav kawm hauv C# thiab tom qab ntawd hla nws mus rau qhov ua haujlwm IronPython. Yog xav paub ntxiv, saib Dynamic Lus Runtime Txheej txheem cej luam.
Tib neeg kuj nug, dab tsi yog hom dynamic hauv net?
Hom Dynamic raws li Method Parameter A txoj kev tuaj yeem muaj hom dynamic parameters soth nws txais tau ib yam hom ntawm parameter thaum khiav. Pointsto Nco ntsoov: Lub dynamic hom kev daws teeb meem ntawm runtimeinstead ntawm compile lub sij hawm. Lub compiler hla lub hom kuaj rau dynamic hom.
Dynamic C# yog dab tsi?
Cov dynamic lo lus tseem ceeb yog tshiab rau C# 4.0, andis siv los qhia rau lub compiler tias qhov sib txawv ntawm hom tuaj yeem hloov lossis tias nws tsis paub txog thaum lub sijhawm ua haujlwm. Xav tias nws muaj peev xwm cuam tshuam nrog Ib Yam Khoom yam tsis tas yuav pov nws. Tam sim no, tau kawg, thaum koj siv a dynamic variable, koj muab upcompiler hom checking.

Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Peb puas tuaj yeem tsim cov khoom dynamic hauv C# thiab DynamicObject yog dab tsi?
Hauv C#, koj qhia meej hom khoom alate-bound li dynamic. Koj tuaj yeem tsim koj tus kheej hom uas tau txais DynamicObjectclass. Tom qab ntawd koj tuaj yeem hla cov tswv cuab ntawm cov chav kawm DynamicObject kom muab sijhawm ua haujlwm dynamicfunctionality
Dab tsi yog sparse kem Dab tsi yog qhov zoo thiab qhov tsis zoo?
Koj poob 4 bytes tsis yog ib zaug ib kab; tab sis rau txhua lub cell hauv kab uas tsis yog null. Qhov zoo ntawm SPARSE kem yog: Qhov tsis zoo ntawm SPARSE kem yog: SPARSE kem tsis tuaj yeem siv rau ntawm cov ntawv, ntext, duab, timestamp, geometry, geography lossis cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
