You can use httpclient to communicate with the microservices. You will have to use DTO to do this. Please refer https://www.hosting.work/aspnet-core-microservices-synchronous-communication/

you are definitely in a wrong track , otherwise you will never need to call a controller method inside another controller . Instead create a class library and put your logic there like Services and call any service from any controller.

suppose you have following methods under your mymicroservices controller PostEmployee GetEmployee PutEmployee DeleteEmployee then you can call them from postman with the same url being http://localhost:portNo/mymicroservices if your method type is selected as post in postman then it will call PostEmployee method similarly if method type is selected as Get then it will call GetEmployee method. so http verb decides which method to call the url will be same withoud any method name untill you use attribute routing.
