OperatingSystem.ServicePack Property

Gets the service pack version represented by this OperatingSystem object.

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

public string ServicePack { get; }

Property Value

Type: System.String
The service pack version, if service packs are supported and at least one is installed; otherwise, an empty string ("").

A service pack is used to distribute software updates for the operating system on which it is installed. However, not every operating system uses service packs.

The service pack version, if available, is already correctly formatted for display.

The following code example demonstrates the ServicePack property.

// This example demonstrates the OperatingSystem.ServicePack property.

class Sample 
    public static void Main() 
    OperatingSystem os = Environment.OSVersion;
    String sp = os.ServicePack;
    Console.WriteLine("Service pack version = \"{0}\"", sp);
This example produces the following results:

Service pack version = "Service Pack 1"
