Taw qhia. Cov Repository qauv yog txhais los ntawm Cov qauv ntawm Enterprise Application Architecture as: Mediates nruab nrab ntawm cov sau npe thiab cov ntaub ntawv qhia cov txheej txheem siv kev sib sau zoo li kev nkag mus rau cov khoom sau npe. Chaw khaws cia muab ib lub cim xeeb zoo li sau interface rau kev nkag mus rau cov khoom sau.
generic repository yog dab tsi? Cov generic repository tsuas yog ib tug tub nkeeg anti-pattern. A generic repository feem ntau yog siv nrog lub hauv paus ntsiab lus kom ceev cov txheej txheem ntawm kev tsim cov ntaub ntawv txheej.

Ntawm no, puas xav tau tus qauv chaw khaws ntaub ntawv nrog Entity Framework?
Qhov zoo tshaj plaws yog vim li cas tsis siv lub cov qauv khaws cia nrog Lub Koom Haum Ua Haujlwm ? Lub Koom Haum Ua Haujlwm xa siv a qhov chaw khaws cia qauv . DbContext yog koj UoW (Unit of Work) thiab txhua DbSet yog qhov chaw cia khoom . Kev siv lwm txheej saum toj no tsis yog tsuas yog rov ua dua, tab sis ua rau kev saib xyuas nyuaj.
Yuav ua li cas siv generic repository qauv hauv MVC?
Cov kauj ruam los siv cov chaw cia khoom dav dav hauv ASP. NET MVC
- Kauj ruam 1 - Ntxiv MVC template tshiab.
- Kauj Ruam 2 - Ntxiv Cov Txheej Txheem Txheej Txheem.
- Peb tab tom yuav xaiv cov lej ua ntej rau kev tsim cov ntaub ntawv thiab cov rooj sib tham.
- Kauj ruam 4 - Tsim studentConext.
- Kauj ruam 5 - Ntxiv database set Initializer.
- Kauj Ruam 6 - Tam sim no ua haujlwm nrog Generic Repository.
