使用指定的选项初始化指定范围中指定 WMI 类的类的新实例 ManagementClass 。该类表示 WMI 中的 Common Information Model （CIM）管理类，例如 Win32_LogicalDisk，它可以表示磁盘驱动器， Win32_Process，后者表示进程（如 Notepad.exe）。

public:
 ManagementClass(System::Management::ManagementScope ^ scope, System::Management::ManagementPath ^ path, System::Management::ObjectGetOptions ^ options);

public ManagementClass(System.Management.ManagementScope scope, System.Management.ManagementPath path, System.Management.ObjectGetOptions options);

new System.Management.ManagementClass : System.Management.ManagementScope * System.Management.ManagementPath * System.Management.ObjectGetOptions -> System.Management.ManagementClass

Public Sub New (scope As ManagementScope, path As ManagementPath, options As ObjectGetOptions)

参数

scope: ManagementScope

一个 ManagementScope ，指定 WMI 类所在的范围（服务器和命名空间）。

path: ManagementPath

一个 ManagementPath 表示指定作用域中 WMI 类的路径。该类表示 WMI 中的 CIM 管理类。 CIM 类表示管理信息，包括硬件、软件、进程等。有关 Windows 中可用的 CIM 类的详细信息，请参阅 CIM 类。

options: ObjectGetOptions

一个 ObjectGetOptions 指定检索 WMI 类时要使用的选项。

示例

以下示例是如何使用构造函数初始化 ManagementClass 变量 ManagementClass 的示例。该示例列出了所创建类的方法、属性和限定符（包括修改后的限定符）。您必须更改代码中的作用域（命名空间），才能在计算机上正确运行。

using System;
using System.Management;

public class Sample
{
    public static void Main()
    {

        // Get the WMI class
        ManagementScope s =

        ManagementPath p = new ManagementPath("Win32_Environment");
        ObjectGetOptions o = new ObjectGetOptions(
            null, System.TimeSpan.MaxValue, true);
        ManagementClass c = new ManagementClass(s, p, o);

        // Get the methods in the class
        MethodDataCollection methods =
            c.Methods;

        // display the methods
        Console.WriteLine("Method Names: ");
        foreach (MethodData method in methods)
        {
            Console.WriteLine(method.Name);
        }
        Console.WriteLine();

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

        // display the properties
        Console.WriteLine("Property Names: ");
        foreach (PropertyData property in properties)
        {
            Console.WriteLine(property.Name);
        }
        Console.WriteLine();

        // Get the Qualifiers in the class
        QualifierDataCollection qualifiers =
            c.Qualifiers;

        // display the qualifiers
        Console.WriteLine("Qualifier Names: ");
        foreach (QualifierData qualifier in qualifiers)
        {
            Console.WriteLine(qualifier.Name);
        }
    }
}
