Impela, sicela ubheke isihloko esingezansi:
Emkhakheni wokuthuthukiswa kokusetshenziswa kubonwa, ikhono lokushintsha umbala wangaphambili welebula ngokushintshashintshayo livumela ukuzizwisa okuthuthukisiwe komsebenzisi futhi lingasiza ngesitayela setimu yohlelo lokusebenza. Ku-C#, lo msebenzi ungafezwa kalula nangokunemba. Kulesi sihloko, singena ekuhloleni ukuthi ungalawula kanjani umbala wangaphambili welebula, unikeze incazelo yekhodi yesinyathelo nesinyathelo, futhi uthinte imitapo yolwazi nemisebenzi ebalulekile kule nqubo.

Ukuhlukanisa Isixazululo
Isixazululo sethu siqala nge Uhlelo.Windows.Amafomu i-namespace, ehlanganisa isethi yezinhlobo zokudala i-interface yomsebenzisi eyisithombe nokuphatha ukuziphatha kwabo. Phakathi kwalezi zinhlobo kukhona Bhala class, elimele ilebula ye-Windows ejwayelekile.
Ikilasi lethu le-Form1 linesibonelo esisodwa se-Label, ilebula1. Ngaphakathi komakhi we-Form1, simisa impahla yelebula1 ethi “Sawubona, Umhlaba!” kanye nempahla yayo ye-ForeColor kuya ku-Red. Isici se-ForeColor siphathelene nombala ongaphambili wesilawuli, othi Ngelebula, uthinte umbala wombhalo.
Lesi senzakalo Selebula sibe sesingezwa kokuthi Izilawuli zefomu - iqoqo lazo zonke izilawuli eziqukethwe ngaphakathi kwefomu.
Ekugcineni, ngaphakathi kwendlela Eyinhloko, siqala i-Form1 yethu futhi siqhube isicelo.
I-System.Windows.Forms Namespace kanye Nekilasi Lelebula
Njengoba kunikezwe indima yayo ebalulekile ekuthuthukiseni izinhlelo zokusebenza ezisekelwe ku-Windows, ukuqonda i- Uhlelo.Windows.Amafomu i-namespace ibalulekile kunoma yimuphi umhleli we-C#. Ihlinzeka ngezilawuli ezihlukahlukene njengezinkinobho, amabhokisi ombhalo, namalebula phakathi kokunye.
The Bhala iklasi, ingxenye yalesi sikhala samagama, iyithuluzi elibalulekile lokubonisa umbhalo kuhlelo lokusebenza. Ngezakhiwo ezihlukahlukene ezifana ne-ForeColor, i-BackColor, ifonti, umbhalo, nokuningi, leli klasi lihlinzeka ngesethi ephelele yezinketho zokukhohlisa ukubukeka nokuziphatha kwamalebula.
Kithina, sisebenzise amandla esakhiwo se-ForeColor ukuze siguqule umbala wombhalo Welebula yethu.
Lawula Amaqoqo kanye Nokwenziwa Kohlelo Lokusebenza
Ngokuya kokusetshenziswa kubonwa, i-ControlCollection idlala indima ebalulekile ekulawuleni izilawuli ezihlukahlukene, njengelebula yethu, ngaphakathi kwefomu. Ngokwengeza Ilebula yethu, ilebula1, Ezilawulweni zefomu lethu, silibeka ngempumelelo kuhlelo lwethu lokusebenza ukuze liboniswe.
I-Application.Run method emsebenzini wethu Oyinhloko injini enikeza ifomu lethu amandla, ithatha isibonelo sethu se-Form1 futhi iyisebenzise njengohlelo lokusebenza. Lokhu Isicelo.Run kuyisinyathelo sokugcina sokwenza Ifomu lethu, kanye nelebula yalo enemibala, liphile.
Sithemba ukuthi lesi sihloko sikunikeze ukuqonda okuqinile kokuthi ungashintsha kanjani umbala wangaphambili welebula ku-C# kanye nendima ebalulekile I-System.Windows.Forms namespace, nesigaba sayo Selebula, zidlala emsebenzini onjalo. Jabulela ukubhala ngekhodi!
