这里我是mvc core2.0的新用户，请帮我解释为什么我的路由不能正常工作 我的路由类

此类文件我在startup.config文件中注册
public static class ApplicationRoteProfiler
{
public static void Routeing(IRouteBuilder builder)
{
builder.MapRoute("route1", "", new
{
Controllers = "Department",
Action = "Add",
});
builder.MapRoute("route2", "Department/Add", new
{
Controllers = "Department",
Action = "Index"
});
}
当我点击我的服务器为 public void Configure(IApplicationBuilder app)
{
app.UseStaticFiles();
app.UseMvc();
app.UseMvcWithDefaultRoute();
app.UseMvc(routes =>
{
ApplicationRoteProfiler.Routeing(routes);
});
}
时，它应该重定向到部门/索引但它点击部门/添加
答案 0 :(得分：2)
应该只是Controller而不是Controllers ??
builder.MapRoute("route1", "", new { controller = "department", action = "index" });
app.UseMvcWithDefaultRoute()和app.UseMvc()。你只需要选择其中的一个。我没有看到使用静态类为MVC配置路由的好处。您可以将所有路径配置放在UseMvc lamba函数中。此外，我认为您不需要专门为您的＆＃34; route1＆＃34;因为它遵循标准的MVC路由约定。
app.UseMvc(routes =>
{
// The order of these routes matters!
routes.MapRoute(
name: "route2",
template: "department/add",
defaults: new { area = "", controller = "department", action = "index" });
routes.MapRoute(
name: "default",
template: "{controller=home}/{action=index}/{id?}");
}
您还可以在return RedirectToAction("index");控制器Department方法中Add，因此每当/deparment/add路由被点击时，它会重定向到/deparment/index，假设您拥有默认的MVC路由设置，使用＆＃34;默认＆＃34;路线我穿上＃2，或使用UseMvcWithDefaultRoute()。这样您就不需要为重定向创建自定义路由。
public class DepartmentController : Controller
{
public IActionResult Index()
{
return View();
}
public IActionResult Add()
{
return RedirectToAction("index");
}
}
