Way to short

[LJ9999]

What I need to know is how to read rocket science like this: Where<TSource>(IEnumerable<TSource>, Func<TSource, Int32, Boolean>)

There is nowhere on the web that explains these fundamentals and yet most of C# is defined this way.

Hi @LJ9999 You will need to read the sections below "Generics", https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/generics/. I don't think that there is anything about this under "classes-and-structs"

The way to read Where<TSource>(IEnumerable<TSource>, Func<TSource, Int32, Boolean>) is that the method called Where is generalised to an arbitrary type, called TSource. The method takes an IEnumerable of this type and a function from this type and an integer to a boolean value.

So if TSource is a string, then the signature would be Where<string>(IEnumerable<string>, Func<string, Int32, Boolean>)

Thanks for bringing this to our attention @LJ9999. I see that @mikkelbu has provided some good information about this topic. Does that help with your question? What else are you looking for?
