If you struggled with INotifyPropertyChanged implementation in C#, you may like my new C# Code Generator (C# 9.0) generating the property implementation in a partial class (see docs). This new strategy for generating code is important because it generates the code in real-time in Visual Studio but also when compiling from the CLI. Also, they do not require no runtime dependency, as everything is just done at build time. https://www.nuget.org/packages/SpeedyGenerators/ Sources and docs here: https://github.com/raffaeler/SpeedyGenerators HTH
Simple Guide On Effective Use Of Parallel Programming For C# In A Managed Code Environment:
Parallel programming in C# uses a variation of Managed Threading, that relies on PLINQ, Expression Trees, The Barrier Class, Thread Class, BackgroundWorker Class, SpinWait Struct, SpinLock Struct, and Thread-Tracking Mode for SpinLock. The reason is that it's faster to use the environment to determine how many cores / threads are available, as to not starve the device of resources, which at that point, you have to use the BackgroundWorker Class to manage each task you've created. Often in this scenario, you can end up with a deadlock condition, because you have more than one task trying to access a shared resource. It's much easier and faster to split up each task, ONLY using byte arrays, assigning each task individual byte arrays to sort / parse, encrypted or not, with the Stream class, or a sub variation of that Class, and then when each task finishes, they all finish at different times, but the shared resource is divided up into portions, so that they will only be able to fill one area of that array. The reason why Barrier is used in this situation, is it forces each one to wait until all the tasks are finished, or until they all ARRIVE at the same place, which solves one timing issue, yet it might create another where there's a bit of a timing mismatch if your estimates are wrong, you overshoot or undershoot I mean. At the very end, you can use a separate process to just COPY from each individual array, without a deadlock scenario occurring. The only issue, is you have to estimate how many threads are available ahead of time, and you can't use every single thread, yet you're going to have to divide a single resource between all those threads. Beforehand, you have to verify if it's a waste of time to use more than one thread. The reason why I say this, is that a lot of people use reference types, not knowing they are immutable, and they take a huge / massive performance hit because of this. Often you have to convert strings into byte arrays, or use a pre-initialized character array at the start of the program, which contains the Unicode values that you want to recast individually as strings, and then use a byte array as an INDEX or a placeholder, of a Unicode character array. If you’re not encrypting the byte arrays, or using them for text parsing, which byte arrays tend to be best in high throughput scenarios, than integer arrays will suffice. The index can be scrambled based on how you want to represent that one string, though it's smarter to only cast a new reference type when you want to display text on the screen. If you spend too much time manually parsing using built-in libraries, it's REALLY SLOW. A byte array is better to use than an integer array in this sort of situation. You might have to create separate indexes with a byte array representing a set of binary flags, to determine whether each one is a letter, number, symbol, etc, or how you want to classify each one based on the code chart that you're using. You would be better off in that situation to just use right shift / left shift / XOR, etc, to set the flags. Then you have something which is also very fast, and almost equivalent to a Barrel Shifter, given C# does not allow you to use pointers, as it's managed code / a managed environment. All the Boolean Logical Operators with Compound Assignment rely on pre-initialized Cast Expressions of Integer Literals, Bitwise and Shift Operators, combined with Lambda Expressions, and Operator Overloading. The purpose of the Shift Operators is to mask / pad the bits of one byte value with zeroes, so that your Cast Expression Of An Integer Literal, which serves at the mask, always gives you a fixed / deterministic result, when used in conjunction with Boolean Logical Operators, especially if the value is smaller than 8-bits / a single byte, or you're dealing with a larger array has to represent a flag "register" with a size of ( 2 ^ 8 ) 256 bits, which is basically a Double-Word: "Microsoft Learn -
