Impela, nansi indatshana yefomu ende mayelana nokuthola indlela esebenzisekayo ku-C#.
Ukuthola indlela esebenzisekayo kuhlelo lokusebenza lwe-C# kuwumsebenzi ovamile wokuhlela ongase uvele njalo ngemva kwesikhathi ohambweni lomuntu lokubhala amakhodi. Kungumsebenzi olula futhi nokho ubalulekile futhi uwusizo kakhulu ngezinjongo ezihlukahlukene. Isibonelo, ingasetshenziswa ukufinyelela amafayela ephrojekthi ahlukahlukene lapho indawo yephrojekthi ingaziwa. Lesi sihloko sizohlukanisa ikhodi oyidingayo ukuze uthole indlela esebenzisekayo, uyichaze kancane kancane, futhi ekugcineni uhlole imibono ehlobene.
Kumongo wohlelo lwe-C#, lo msebenzi ungafezwa ngomugqa owodwa nje wekhodi. Ngakho-ke ake siqonde ngqo kwisixazululo:
System.AppDomain.CurrentDomain.BaseDirectory
Umugqa wekhodi ongenhla umane ubuyisela indlela yefayela elisebenzisekayo (.exe) lohlelo lokusebenza olusebenzayo njengamanje, ngendlela yochungechunge.
The I-AppDomain.CurrentDomain.BaseDirectory impahla ithola uhla lwemibhalo oluyisisekelo olusetshenziswa isixazululi somhlangano ukuze siphenyele imihlangano.
Ukuqonda Ikhodi: Incazelo Yesinyathelo Nesinyathelo
Ku-C #, i I-AppDomain ikilasi liyingxenye ebalulekile ye-.NET framework's System indawo yamagama. Uhlelo lokusebenza ngalunye lwe-NET lunesibonelo okungenani esisodwa I-AppDomain. Lesi sibonelo sidalwa lapho uhlelo luqala. Lonke uhlelo olusha lunalo I-AppDomain lokho kuligcina lihlukile kwezinye izinhlelo zokusebenza, okuwusizo ekuthuthukiseni ukuvikeleka nokuqina kohlelo lokusebenza.
I-CurrentDomain, ngakolunye uhlangothi, iyimpahla ye- I-AppDomain ikilasi. Ibuyisela into ekhomba isizinda sohlelo lokusebenza lwamanje kuchungechunge olusebenzayo.
Okokugcina, i I-BaseDirectory impahla yababuyisiwe I-AppDomain into ibuyisela indlela yohla lwemibhalo lapho ifayela elisebenzisekayo lohlelo lokusebenza likhona.
Ngakho, ukuhlanganisa konke:
- I-AppDomain.CurrentDomain usitholela isizinda sohlelo lokusebenza lwamanje.
- I-BaseDirectory isinika inkomba eyisisekelo yesizinda sohlelo lokusebenza samanje.
Ngamafuphi, ikhodi yomugqa owodwa eshiwo ngenhla isinikeza indlela yohla lwemibhalo lapho kukhona khona umhlangano osebenzisekayo wohlelo lokusebenza olusebenzayo njengamanje.
I-System Namespace kanye ne-AppDomain Class
The System i-namespace ingenye yezikhala zamagama ezisetshenziswa kakhulu ku-C#. Kuhlanganisa amakilasi ayisisekelo namakilasi ayisisekelo achaza amanani asetshenziswa kakhulu nezinhlobo zedatha eyireferensi, imicimbi nezibambi zemicimbi, izixhumanisi, izibaluli, kanye nokucubungula okuhlukile.
I-AppDomain ikilasi elakha ingxenye ebalulekile ye- System namespace, futhi isebenza ngezinhloso ezahlukahlukene:
- Ihlinzeka ngendawo yesikhathi sokusebenza ene-sandboxed engalawulwa futhi ilayishwe ngesethi ethile yemihlangano.
- Ingalungiselelwa, okuvumela ukulungiselelwa okufana nenqubomgomo yokuvikeleka ukuthi isethwe.
- Ingathululwa, okuyenza isebenziseke uma kuziwa ekuphathweni kwezinsiza.
Ngakho-ke, isakhiwo se-AppDomain.CurrentDomain.BaseDirectory, sihlinzeka ngendlela eguquguqukayo yokufinyelela uhla lwemibhalo lwefayela elisebenzisekayo lohlelo lokusebenza olusebenzayo njengamanje, okulenza libe ithuluzi elibalulekile kukhithi yamathuluzi yomhleli we-C#.
Kusukela lapha, imiqondo ethuthuke kakhulu ingacutshungulwa njengokusetshenziswa kwe-AppDomain ye-Runtime Executable's isolation, Reflection, Configuring AppDomain, nokuningi, konke okudinga ukuqonda okuhle kwesihloko samanje. Lokhu kuwubufakazi bendlela ukwakhiwa okuyisisekelo ohlelweni ngokuvamile kusebenza njengesango lezingxenye eziyinkimbinkimbi nezithakazelisa kakhulu zenkundla.
Ukusebenzisa indlela esebenzisekayo kukhodi yakho
Uma usunendlela, ukwenza imisebenzi efana nokufinyelela amafayela, ukukhiqiza izingodo, njll. kuba lula. Nasi isibonelo sekhodi sokuthi ungasebenzisa kanjani i-BaseDirectory ukuze ufinyelele ifayela:
string filePath = System.AppDomain.CurrentDomain.BaseDirectory + @“DataDetails.txt”;
usebenzisa (i-StreamReader sr = i-StreamReader entsha(filePath))
{
// Ikhodi yakho lapha
}
Kule khodi, simane sihlanganisa indlela yohla lwemibhalo eyisisekelo nendlela ehlobene ye-'Details.txt' kuhla lwemibhalo 'lwedatha' nokuyifunda. Le khodi izosebenza ngempumelelo kungakhathaliseki indawo yamanje yephrojekthi yakho, ngaleyo ndlela yengeze ekuguquguqukeni kwekhodi yakho.
Njengoba uqhubeka nokusebenza kumaphrojekthi amaningi futhi uthola ulwazi oluthe xaxa nge-C# kanye nohlaka lwe-.NET, uzohlangabezana nezinsiza eziningi ezinjalo ezilindele ukuxhashazwa. Futhi qiniseka, lapho ufunda okwengeziwe, uma unamathuluzi engeziwe onawo, kuzoba mkhulu umyalo wakho phezu kwekhodi yakho. Jabulela ukubhala ngekhodi!
