Heap sorting is a sort method that has the common advantage of combining sort and insert sort. Its time complexity is O (NLGN), which is also an in-place sorting algorithm: At any time, only a constant number of elements in an array are stored

Another concept originated from functional programming languages is added to the C # and VB camps, which are known as pattern matching. At first glance, pattern matching works like a switch/SELECT statement block, but it has many powerful functions.

There are many methods for this. 1. Use pinvok to call the pathrelativepathto of Windows API 2. Process strings by yourself 3. Use URI If you don't want to talk about the first two types, you may feel a little troublesome. If you want to know more
