Assembly:  System.Management (in System.Management.dll)
Syntax
Visual Basic
Public Class ManagementPath _
	Implements ICloneable
C#

The ManagementPath type exposes the following members.

Constructors
  Name Description
Public method ManagementPath() Initializes a new instance of the ManagementPath class that is empty. This is the default constructor.
Public method ManagementPath(String) Initializes a new instance of the ManagementPath class for the given path.
Top
Properties
  Name Description
Public property ClassName Gets or sets the class portion of the path.
Public property Static member DefaultPath Gets or sets the default scope path used when no scope is specified. The default scope is \\.\root\cimv2, and can be changed by setting this property.
Public property IsClass Gets or sets a value indicating whether this is a class path.
Public property IsInstance Gets or sets a value indicating whether this is an instance path.
Public property IsSingleton Gets or sets a value indicating whether this is a singleton instance path.
Public property NamespacePath Gets or sets the namespace part of the path. Note that this does not include the server name, which can be retrieved separately.
Public property Path Gets or sets the string representation of the full path in the object.
Public property RelativePath Gets or sets the relative path: class name and keys only.
Public property Server Gets or sets the server part of the path.

Methods
  Name Description
Public method Clone Returns a copy of the ManagementPath.
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method SetAsClass Sets the path as a new class path. This means that the path must have a class name but not key values.
Public method SetAsSingleton Sets the path as a new singleton object path. This means that it is a path to an instance but there are no key values.
Public method ToString Returns the full object path as the string representation. (Overrides Object.ToString().)

Explicit Interface Implementations
  Name Description
Explicit interface implemetation Private method ICloneable.Clone Creates a new object that is a copy of the current instance.

Examples

The following example demonstrates how the ManagementPath class parses a path to a WMI object. The path that is parsed in the example is a path to an instance of a class.

Visual Basic

Imports System
Imports System.Management


Public Class Sample
    Public Overloads Shared Function _
        Main(ByVal args() As String) As Integer

        ' Get the WMI class path
        Dim p As ManagementPath = _
            New ManagementPath( _
            "\\ComputerName\root" & _
            "\cimv2:Win32_LogicalDisk.DeviceID=""C:""")

        Console.WriteLine("IsClass: " & _
            p.IsClass)
        ' Should be False (because it is an instance)

        Console.WriteLine("IsInstance: " & _
            p.IsInstance)
        ' Should be True

        Console.WriteLine("ClassName: " & _
            p.ClassName)
        ' Should be "Win32_LogicalDisk"

        Console.WriteLine("NamespacePath: " & _
            p.NamespacePath)
        ' Should be "ComputerName\cimv2"

        Console.WriteLine("Server: " & _
            p.Server)
        ' Should be "ComputerName"

        Console.WriteLine("Path: " & _
            p.Path)
        ' Should be "ComputerName\root\cimv2:
        ' Win32_LogicalDisk.DeviceId="C:""

        Console.WriteLine("RelativePath: " & _
            p.RelativePath)
        ' Should be "Win32_LogicalDisk.DeviceID="C:""

    End Function
End Class
C#

using System;
using System.Management;

public class Sample 
{    
    public static void Main() 
    {

        // Get the WMI class path
        ManagementPath p = 
            new ManagementPath(
            "\\\\ComputerName\\root" +
            "\\cimv2:Win32_LogicalDisk.DeviceID=\"C:\"");

        Console.WriteLine("IsClass: " +
            p.IsClass);
        // Should be False (because it is an instance)

        Console.WriteLine("IsInstance: " +
            p.IsInstance);
        // Should be True

        Console.WriteLine("ClassName: " +
            p.ClassName);
        // Should be "Win32_LogicalDisk"

        Console.WriteLine("NamespacePath: " +
            p.NamespacePath);
        // Should be "ComputerName\cimv2"

        Console.WriteLine("Server: " + 
            p.Server);
        // Should be "ComputerName"

        Console.WriteLine("Path: " +
            p.Path);
        // Should be "ComputerName\root\cimv2:
        // Win32_LogicalDisk.DeviceId="C:""

        Console.WriteLine("RelativePath: " +
            p.RelativePath);
        // Should be "Win32_LogicalDisk.DeviceID="C:""

    }
}
