The following code example demonstrates the VersionString property.

// This example demonstrates the VersionString property.
using namespace System;
int main()
{
   OperatingSystem^ os = Environment::OSVersion;
   
   // Display the value of OperatingSystem.VersionString. By default, this is
   // the same value as OperatingSystem.ToString.
   Console::WriteLine( L"This operating system is {0}", os->VersionString );
   return 0;
}

/*
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.
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 demonstrates the VersionString property.
open System

let os = Environment.OSVersion
// Display the value of OperatingSystem.VersionString. By default, this is
// the same value as OperatingSystem.ToString.
printfn $"This operating system is {os.VersionString}"
// This example produces the following results:
//    This operating system is Microsoft Windows NT 5.1.2600.0 Service Pack 1

Class Sample
   Public Shared Sub Main()
      Dim os As OperatingSystem = 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)

   End Sub
End Class

Remarks

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.

For a list of Windows operating system versions and their corresponding version numbers, see Operating System Version.
