示例

下面的代码示例演示 了 ServicePack 属性。

// This example demonstrates the OperatingSystem.ServicePack property.
using namespace System;
int 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"

*/

// This example demonstrates the OperatingSystem.ServicePack property.
using System;

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"

*/

// This example demonstrates the OperatingSystem.ServicePack property.
open System

let os = Environment.OSVersion
let sp = os.ServicePack
printfn $"Service pack version = \"{sp}\""
// This example produces the following results:
//     Service pack version = "Service Pack 1"

' This example demonstrates the OperatingSystem.ServicePack property.
Class Sample
   Public Shared Sub Main()
      Dim os As OperatingSystem = Environment.OSVersion
      Console.WriteLine("Service pack version = ""{0}""", os.ServicePack)
   End Sub
End Class
'
'This example produces the following results:
'
'Service pack version = "Service Pack 1"
'

注解

Service Pack 用于分发安装它的操作系统的软件更新。 但是，并非每个操作系统都使用 Service Pack。

Service Pack 版本（如果可用）已正确设置显示格式。
