OperatingSystem.VersionString Property

Note: This property is new in the .NET Framework version 2.0.

Gets the concatenated string representation of the platform identifier, version, and service pack that are currently installed on the operating system.

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

public string VersionString { get; }
/** @property */
public String get_VersionString ()

public function get VersionString () : String

Property Value

The string representation of the values returned by the Platform, Version, and ServicePack properties.

By default, the value returned by VersionString is the same as the value returned by the ToString method. However, an implementation of the .NET Framework for a different platform might return a more appropriate string for that platform.

The following code example demonstrates the VersionString property.

// This example demonstrates the VersionString property.
using System;

class Sample 
{
    public static void Main() 
    {
    OperatingSystem os = Environment.OSVersion;
// Display the value of OperatingSystem.VersionString. By default, this is
// the same value as OperatingSystem.ToString.
    Console.WriteLine("This operating system is {0}", os.VersionString);
    }
}
/*
This example produces the following results:

This operating system is Microsoft Windows NT 5.1.2600.0 Service Pack 1
*/

// This example demonstrates the VersionString property.
import System.*;

class Sample
{
    public static void main(String[] args)
    {
        OperatingSystem os = Environment.get_OSVersion();
        // Display the value of OperatingSystem.VersionString. By default, 
        // this is the same value as OperatingSystem.ToString.
        Console.WriteLine("This operating system is {0}", 
            os.get_VersionString());
    } //main
} //Sample
