Problem
How can I define a route in a way closer to a resource (Controller or Action.
Solution
You can use Attribute routing to directly declare a route at the resource level. You only need to simply use RouteAttribute on the Action, and then pass a relevant routing template.
First, the basic idea of inserting sortStarting from the initial ordered subset, the new data elements are constantly inserted into the appropriate position of the ordered sub-set, so that the number of data elements in the child collection is increasing, and when the sub-collection equals the collection, the insertion sort algorithm ends. The commonly used insertion sorting algorithm has two kinds of direct insertion sort and hill sort. Second,
The previous article summarizes the bubble sort and quick sort of the interchange sort. This article summarizes the selection of sorting, the choice of sorting is divided into direct selection of sorting and heap sorting, mainly from the following points to summarize.1. Direct selection sequencing and algorithm implementation2. Heap sequencing and algorithm implementation1.
The basic idea of direct insertion sort (insertion sort) is to insert a record to be sorted each time by its keyword size into the appropriate position in the previously sorted subsequence until all records are inserted.
Set array to a[0...n-1].
1. At the initial time, the a[0] is a 1 ordered region and the disordered region is a[1..n-1]. Make I=1
2. A[i] is merged into the current ordered area A[0...i-1] t
Introduction:
Insert sorting is the simplest and easier-to-understand sorting algorithm. This article describes in detail the direct insertion sorting, provides implementation, briefly introduces the semi-insertion sorting, and provides two types of insert sorting: 2-path insertion sorting and table insertion sorting, but does not provide specific implementation.

ProblemHow can you define a route in a way that is closer to the resource (controller,action).Solution SolutionsYou can use attribute routing to declare routes directly at the resource level. Simply use the attribute route Routeattribute on the Action, and then pass a related route template to it. Attribute routing is essentially the same as a centralized route in the meaning of a route template, and all route parameters should use curly braces and match the Action used.
