GetHashCode feem ntau tshwm sim rau ib lub hom phiaj: los ua haujlwm hash thaum cov khoom siv los ua tus yuam sij hauv lub rooj hash. … Lub rooj hash yog cov qauv ntaub ntawv uas koom nrog tus nqi nrog tus yuam sij.
Lub hom phiaj ntawm GetHashCode yog dab tsi?
Tus GetHashCode txoj kev muab qhov no hash code rau algorithms uas xav tau kev kuaj xyuas sai ntawm cov khoom sib npaug Rau cov ntaub ntawv hais txog yuav ua li cas cov lej hash siv hauv cov rooj hash thiab rau qee qhov ntxiv hash code algorithms, saib Hash Function nkag hauv Wikipedia. Ob yam khoom uas sib npaug rov qab hash codes uas sib npaug.
Kuv puas yuav tsum tau siv GetHashCode?
Nws yog ib qho tseem ceeb rau ua ob qhov sib npaug thiab gethashcode, vim kev sib tsoo, tshwj xeeb yog thaum siv phau ntawv txhais lus. yog tias ob qho khoom rov qab tib tus hashcode, lawv tau muab tso rau hauv phau ntawv txhais lus nrog chaining. Thaum nkag mus rau cov khoom sib npaug yog siv.
Thaum twg peb yuav tsum hla GetHashCode?
Yog tias koj tab tom siv hom kev siv, koj yuav tsum txiav txim siab hla txoj kev sib npaug yog tias koj hom zoo li lub hauv paus hom, xws li Point, String, BigNumber, thiab lwm yam. Override tus GetHashCode txoj kev tso cai ib hom ua haujlwm kom raug hauv lub rooj hash Nyeem ntxiv cov lus qhia ntawm cov neeg ua haujlwm sib luag.
Tus hash hauv code yog dab tsi?
Hashing yog tsuas yog dhau qee cov ntaub ntawv los ntawm cov qauv uas ua rau qhov tshwm sim, hu ua hash. Qhov hash feem ntau yog ib txoj hlua ntawm cov cim thiab cov hashes tsim los ntawm cov qauv yog ib txwm ntev, tsis hais cov ntaub ntawv ntau npaum li cas koj pub rau hauv nws. Piv txwv li, tus qauv MD5 ib txwm tsim 32 cim-ntev hashes.
