I can say I know C#.net now because System.Collections.Generic is a namespace in the .NET Framework, including in C# and Unity. foreach loop is used to iterate over a collection, such as an array, list, dictionary, or any other enumerable type var keyword is used to implicitly declare a variable without specifying its type. The compiler automatically determines the type of the variable based on the right-hand side of the assignment or the context (like a loop or a method return value) Dictionary foreach (var pair in myDictionary) { } var pair: var is an implicit type. The C# compiler automatically determines the type of pair based on the collection you're iterating over. So, pair is a KeyValuePair So pair is actually a variable of type KeyValuePair pair.Key gives you the key pair.Value gives you the corresponding value dictionary hashes the keys internally.  Can You Access Items by Index? No - you can't access a dictionary's values by a numeric index like quotes[0] or quotes[1]. It's key-based only. A Dictionary in C# is built on a hash table dictionary["myKey"] is very fast because it doesn't search through the collection; it just jumps to where it expects the data to be based on the hash NET Core and Later Versions: Small Twist Maintains index order  No (but insertion order is preserved in newer .NET versions) That change was mainly for developer convenience, not to make Dictionary work like a List. In .NET Core 3.0+ and .NET 5+, Microsoft did start making insertion order predictable for Dictionary When you create a Dictionary (or most other objects in C#), the data is stored in your program's memory - specifically on the heap. Here's how it works: 1) Heap vs. Stack in C# Stack: Used for storing simple values and method call info (like int, float, local variables). Heap: Used for storing objects, including complex types like Dictionary, List, and user-defined classes. It allows Unity to run C# code on many platforms: Windows, macOS, Android, iOS, WebGL, etc. Internally, Unity uses Mono to run it - but you're working with the .NET class library Unity uses Mono as the runtime and relies on .NET libraries/APIs for scripting. You're writing standard C# with access to most of the .NET Base Class Library. You can apply your Unity C# skills to .NET-based applications (e.g., desktop apps, web apps, etc.) because they share the same .NET core libraries. Initially it said C# did not have a Dictionary but that may be because it thought I was talking about Python from the beginning of our conversation. It also recommended a list of Dictionaries but I may not have worded what coding goal I was trying to achieve to it. I've learned that asking direct questions with no extra information can sometimes provide a more accurate answer. But sometimes doing the opposite giving it a lot of information can allow it to tell me something new that I may have missed or not thought to ask about which can lead to adding a new feature to the program that makes it more interesting and useful. |
