PHP has functionality to show you the current running configuration of your application and the system it is running on by just calling phpinfo(). It is simple to do this. Just create a file in your site with the following code:
<?php phpinfo(); ?>
Unfortunately, ASP.NET MVC does not provide this functionality. So what I am going to do is show you how you can do this from within ASP.NET MVC.
Note: I found this project and ported the code to work with ASP.NET MVC. If you want to contribute, I put my version up on Github here. This project could use improvements!
The SysInfo Class
Create a new class file called SysInfo.cs in your Models folder and add the following code (notice all the new ‘using’ statements:
using System;
using System.Collections;
using System.Data;
using System.IO;
using System.Reflection;
using System.Runtime.InteropServices;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
namespace Sysinfo_MVC_AspNet.Models
{
public class SysInfo
{
private HttpContext _context;
public SysInfo(HttpContext context)
{
_context = context;
}
public string GetData()
{
string Content = "";
Content += LoadInformation(GetSystemInfo());
Content += LoadInformation(GetSystemProcessorInfo());
Content += LoadInformation(GetSystemMemoryInfo());

Display the System Info
Now that we have the core SysInfo class, we need to display it. Create a new Model called SysInfoViewModel and add the following:
public class SysInfoViewModel
{
public string BodyContent { get; set; }
public SysInfoViewModel(string content)
{
this.BodyContent = content;
}
}
Locate your HomeController and add a new action. I called mine GetSysInfo(). Here is the code:
public ActionResult GetSysInfo()
{
//Make sure <trust level="Full" /> is in <system.Web>
SysInfo info = new SysInfo(System.Web.HttpContext.Current);
SysInfoViewModel model = new SysInfoViewModel(info.GetData());
return View(model);
}
Now using GetSysInfo(), create a new view and add the following:
@model Sysinfo_MVC_AspNet.Models.SysInfoViewModel
@{
ViewBag.Title = "System Information";
}
<style type="text/css">
/*a:link {

Shared Hosting Trust Permissions
So this is a great tool if you need some information while developing on your local computer but what if you need to deploy this to a shared hosting server? There is no easy answer to solve the trust permissions that your hosting provider may put in place. What I have found to work where I have deployed my code is to add the following configuration setting in the web.config.
<trust level="Full"/>
Conclusion
You need to be aware that this code provides a lot of information about your application and server to hackers. You should probably secure access to the GetSysInfo() in your controller and not make it publicly available.
Happy coding!
