Custom Error Handler Asp.net Mvc
Contents |
you're not alone. It's surprisingly difficult to do this correctly, not helped by the fact that some errors are handled by ASP.NET and others mvc custom error handling by IIS. Ideally (and I expect such is the case with some custom error handling in mvc 4 other frameworks/servers) we would just configure our custom error pages in one place and it would just work, no mvc 5 error handling matter how/where the error was raised. Something like:
Asp.net Mvc Custom Error Page
is very simple, but you can see some really nice examples here.
404 Page Not Found
I created a new ASP.NET MVC 5 application using the standard template in Visual Studio. If I run the site and try to navigate to a resource that does not exist e.g. /foo/bar, I'll get the standard ASP.NET 404 page with the following information: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /foo/bar Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.33440 Not exactly friendly, is it? In this case the error was raised by ASP.NET MVC because it could not find a matching controller and/or action that matched the specified URL. In order to set up a custom 404 error page add the following to web.config insideLatest Articles Latest Tips/Tricks Top Articles Beginner Articles Technical Blogs Posting/Update Guidelines Article Help Forum Article Competition Submit

You can add a simple exception page, meant only for use during development, very easily. All that's required is to add a dependency on Microsoft.AspNetCore.Diagnostics to the project and then add one line to Configure() in Startup.cs: public void Configure(IApplicationBuilder app, IHostingEnvironment env) { app.UseIISPlatformHandler(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } The above code includes a check to ensure the environment is development before adding the call to UseDeveloperExceptionPage. This is a good practice, since you typically do not want to share detailed exception information about your application publicly while it is in production. Learn more about configuring environments. The sample application includes a simple mechanism for creating an exception: public static void HomePage(IApplicationBuilder app) { app.Run(async (context) => { if (context.Request.Query.ContainsKey("throw")) { throw new Exception("Exception triggered!"); } var builder = new StringBuilder(); builder.AppendLine("
Hello World!"); builder.AppendLine("- "); builder.AppendLine("
