C#-এ HybridDictionary ক্লাস

HybridDictionary ক্লাস IDictionary ইমপ্লিমেন্ট করে। এটি ছোট কালেকশনে ListDictionary (লিঙ্কড লিস্ট) ব্যবহার করে এবং আকার বড় হলে স্বয়ংক্রিয়ভাবে Hashtable-এ স্বিচ করে। এটি পারফরম্যান্স অপ্টিমাইজেশনের জন্য ডিজাইন করা।

    }

গুরুত্বপূর্ণ টিপস

• ১০-১৫ এলিমেন্টের নিচে ListDictionary, তার উপরে Hashtable ব্যবহার করে।
• Equals রেফারেন্স সমতা চেক করে, কন্টেন্ট নয়।
• সিঙ্ক্রোনাইজেশন জন্য lock(dict.SyncRoot) ব্যবহার করুন।
