ASP.NET Core MVC通过IViewLocationExpander扩展视图搜索路径的实现_实用技巧_

 public class MyViewLocationExpander : IViewLocationExpander { public IEnumerable ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable viewLocations) { if (context.ControllerName != null && context.ControllerName.StartsWith("App")) { viewLocations = viewLocations.Concat( new[] { $"/Areas/sysManage/Views/App/{context.ControllerName}/{context.ViewName}{RazorViewEngine.ViewExtension}" }); return viewLocations; } if (context.AreaName != "sysManage") return viewLocations; viewLocations = viewLocations.Concat( new[] { $"/Areas/sysManage/Views/System/{context.ControllerName}/{context.ViewName}{RazorViewEngine.ViewExtension}" }); return viewLocations; } public void PopulateValues(ViewLocationExpanderContext context) { } }

 public void ConfigureServices(IServiceCollection services) { services.Configure(o => { o.ViewLocationExpanders.Add(new MyViewLocationExpander()); }); services.AddMvc(); } 

 app.UseEndpoints(endpoints => { endpoints.MapRazorPages(); endpoints.MapAreaControllerRoute( name: "sysManage", "sysManage", pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}"); });
