ASP.Net Core MVC Routing Issue

Question

I am working on a project (Developed by using .Net Core), I have set some routes and one of them is not working e.g.

1) routes.MapRoute("HRDetail", "H-R/{TName}/{MId}", new { controller = "ABC", action = "XYZ1" });
2) routes.MapRoute("CL", "{SName}/{CName}/{CId}", new { controller = "ABC", action = "XYZ2" });

I have written the code in the same sequence in Startup class, and my action methods are as follows.

public async Task<IActionResult> XYZ2(string SName, string CName, Int16 CId)
{//for route#2}
public async Task<IActionResult> XYZ1( string TName, Int64 MId)
{//for route#1}

Now I want to hit on XYZ1 by using route#1 and the link (to hit on XYZ1 is being created dynamically) is like this http://localhost:4321/H-R/UK/1234. But the problem is that when i click on this link, it always take me to XYZ2 method.
I didn't set any route on controller or action method level.
Is there any solution plz?

Answer 1

It seems, The route are getting confused. There are two ways you can fix this. 1) in your first route specify the regular expression which will say that first parameter will be a fixed string as H-R 2) in you second route specify the regular expression which will say that first parameter will never be H-R

1st

routes.MapRoute("HRDetail", "{ActionName}/{TName}/{MId}", new { controller = "ABC", action = "XYZ1" }, new{ActionName = "$your regularexpression to include only H-R$"});

OR

routes.MapRoute("CL", "{SName}/{CName}/{CId}", new { controller = "ABC", action = "XYZ2" }, new {SName = "$your regularexpression to exclude H-R$" });

PS: you need to put some efforts for regular expression
