Environment.UserInteractive Property

Gets a value indicating whether the current process is running in user interactive mode.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static bool UserInteractive { get; }

Property Value

Type: System.Boolean
true if the current process is running in user interactive mode; otherwise, false.

The UserInteractive property reports false for a Windows process or a service like IIS that runs without a user interface. If this property is false, do not display modal dialogs or message boxes because there is no graphical user interface for the user to interact with.

The following example displays whether the current process is running in user interactive mode.

// Sample for the Environment.UserInteractive property
using System;

class Sample 
    public static void Main() 
    Console.WriteLine("UserInteractive: {0}", Environment.UserInteractive);
This example produces the following results:

UserInteractive: True
