# Kalit so'zlar

Kalit so'zlar kompilyator uchun maxsus ma'nolarga ega bo'lgan oldindan belgilangan, zaxiralangan identifikatorlardir. Ular @ prefiksisiz dasturlarda identifikator sifatida ishlatilishi mumkin emas. Masalan, @if haqiqiy identifikator hisoblanadi, lekin if emas chunki bu kalit so'z bo'ladi. Ushbu maqoladagi birinchi jadvalda C# dasturining biron bir qismida identifikator sifatida ishlatib bo'lmaydigan kalit so'zlar keltirilgan. Ushbu maqoladagi ikkinchi jadvalda kontekstli C# kalit so'zlari keltirilgan. Kontekstli kalit so'zlar faqat ma'lum bir dastur kontekstida ishlatish mumkin va bu kontekstdan tashqarida identifikator sifatida foydalanish mumkin. Odatda, oldingi versiyalarda yaratilgan dasturlarni buzmaslik uchun yangi kalit so'zlar kontekstli kalit so'zlar sifatida C# tiliga qo'shiladi.

*Kontekstli kalit so'zlar***:**

 Kontekst kalit so'zi kodning o'ziga xos ma'nosini ta'minlash uchun ishlatiladi, ammo bu C# -da saqlangan so'z emas. partial va where kabi ba'zi bir kontekstli kalit so'zlar ikki yoki undan ortiq kontekstda maxsus ma'nolarga ega.
