Use the T4 template to generate the constructors and parameters of the ASP. NET Core controller, t4corePreface
In ASP.. NET Core introduces DI, and through the constructor injection parameters, the Controller will inject a large number of configuration parameters using DI.

In this administration system, many T4 templates are used to generate code. So what is the T4 template, and why use the T4 template? Here's a quick look at how it works.When you create a T4 template, the following code snippet appears by default:The above code is the instruction block in the
T4: Reverse Order
A [I] is the prefix and
Derivation (A [J]-A [I])/(J-I)> = m
A [J]-A [I]> = m (J-I)
A [J]-M * j> = A [I]-M * I
Set B [] = A []-M *();
B [J]> = B [I]
That is, reverse order;
There are two methods for reverse order query:
Merge and sort;
Tree array;
The following two methods are available:
1. Previously, only single-point modification and interval summation were used for tree arrays.
