Are you yet another .NET programmer who's afraid of the Aggregate LINQ operator? You shouldn't be.
Aggregate applies to any collection or sequence.
Its principal form takes the first element of the sequence as the running result, and then applies a function to the current result and each upcoming element to obtain new current result.
Its return type is the same as that of the sequence, and it will fail if the sequence is empty.
A more powerful form takes the initial result. It applies a function to the current result and each element in the sequence.
The return type is the type of the seed, and this overload will not fail if the sequence is empty.

👨 About Me 👨
Hi, I’m Zoran, I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️
