👨🏿‍🌾 🤟🏻 👩🏼‍🤝‍👨🏽 उन लोगों के लिए रनटाइम .Net कोड पीढ़ी जिनके पास समय नहीं है 📘 👃🏿 🕶️

इन्फ्रास्ट्रक्चर। नेट में बिल्ट-इन कोड जेनरेशन (ऑन-द-फ्लाई कोड जेनरेशन) होता है। यह .Net कार्यक्रम को इसके निष्पादन के समय स्वतंत्र रूप से (प्रोग्रामर की भागीदारी के बिना) किसी भी प्रोग्रामिंग भाषा में लिखे गए पाठ को संकलित करने और परिणामी कोड को निष्पादित करने की अनुमति देता है। यह अपेक्षा करना तर्कसंगत होगा कि मानक .Net पुस्तकालय में इन कार्यों के कार्यान्वयन के लिए संबंधित वर्ग की सबसे सरल विधि प्रदान की जाती है। लेकिन दुर्भाग्य से ऐसा नहीं है। Microsoft, .नेट वातावरण में कोड जनरेशन टूल्स को एम्बेड करने के लिए एक लंबा रास्ता तय कर रहा है, जिसने प्रोग्रामर की सरलतम जरूरतों की दिशा में बहुत अंतिम कदम नहीं उठाया है। तो, आपको यह कदम खुद उठाना होगा।

Microsoft द्वारा वर्णित समस्या को हल करने का सबसे सरल उपकरण CSharpCodeProvider वर्ग है, जो मानक .Net लाइब्रेरी का हिस्सा है। इस वर्ग का उपयोग करना बहुत मुश्किल काम नहीं है, लेकिन फिर भी यह एक उपकरण के लिए उपयोगी होगा जो ऑन-द-फ्लाई जनरेट कोड के उपयोग को एक तुच्छ कार्य में बदल देता है।

परिणाम कक्षाओं का एक छोटा सा सेट है, जिसका केंद्र Tech.DynamicCoding.CodeGenerator । हम एक साधारण उपयोग के मामले के साथ अपना विवरण शुरू करते हैं। (पुस्तकालय के ग्रंथ और उदाहरण संग्रह में हैं )।

सरल कोड पीढ़ी

मान लें कि आपको पाठ रूप में दिए गए संख्यात्मक अभिव्यक्ति के मूल्य की गणना करने की आवश्यकता है। उदाहरण के लिए, यहां "12345678 * 9 + 9" है। इस मामले में, आपको बस निम्नलिखित लिखने की आवश्यकता है:

 var result = CodeGenerator.ExecuteCode<int>("return 12345678 * 9 + 9;");

सबसे पहले, आप एक C # कोड का एक टुकड़ा बनाते हैं और इसे
