示例

以下示例使用 类PropertyData列出有关 Win32_OperatingSystem 类的信息。 有关 Win32_OperatingSystem的详细信息，请参阅 Windows Management Instrumentation 文档。

using System;
using System.Management;

public class Sample
{
    public static void Main()
    {

        // Get the WMI class
        ManagementClass osClass =
            new ManagementClass("Win32_OperatingSystem");

        osClass.Options.UseAmendedQualifiers = true;

        // Get the Properties in the class
        PropertyDataCollection properties =
            osClass.Properties;

        // display the Property names
        Console.WriteLine("Property Name: ");
        foreach (PropertyData property in properties)
        {
            Console.WriteLine(
                "---------------------------------------");
            Console.WriteLine(property.Name);
            Console.WriteLine("Description: " +
                property.Qualifiers["Description"].Value);
            Console.WriteLine();

            Console.WriteLine("Type: ");
