示例

下面的示例将枚举Win32_LogicalDisk类的所有实例, 并显示每个实例的DeviceID值。The following example enumerates through all of the instances of the Win32_LogicalDisk class, and displays the DeviceID value for each instance.

using System; 
using System.Management;
 
// This example demonstrates how to
// enumerate all logical disks 
// using the ManagementObjectEnumerator object.
class Sample_ManagementObjectEnumerator 
{
    public static int Main(string[] args) 
    { 
        ManagementClass diskClass = 
            new ManagementClass("Win32_LogicalDisk");
        ManagementObjectCollection disks = 
            diskClass.GetInstances();
        ManagementObjectCollection.ManagementObjectEnumerator
            disksEnumerator =
            disks.GetEnumerator();
        while(disksEnumerator.MoveNext()) 
        { 
            ManagementObject disk = 
                (ManagementObject)disksEnumerator.Current;
            Console.WriteLine(
                "Disk found: " + disk["deviceid"]);
        }
        return 0;
    }
}

Imports System.Management

' This sample demonstrates how to
' enumerate all logical disks
' using ManagementObjectEnumerator object.
Class Sample_ManagementObjectEnumerator
    Public Overloads Shared Function _
        Main(ByVal args() As String) As Integer
        Dim diskClass As New _
            ManagementClass("Win32_LogicalDisk")
        Dim disks As ManagementObjectCollection = _
            diskClass.GetInstances()
        Dim disksEnumerator As _
        ManagementObjectCollection. _
            ManagementObjectEnumerator = _
            disks.GetEnumerator()
        While disksEnumerator.MoveNext()
            Dim disk As ManagementObject = _
            CType(disksEnumerator.Current, _
                ManagementObject)
            Console.WriteLine("Disk found: " & disk("deviceid"))
        End While
        Return 0
    End Function
End Class

属性

Current

获取该枚举数指向的当前 ManagementBaseObject。Gets the current ManagementBaseObject that this enumerator points to.

方法

Dispose()

释放与该对象关联的资源。Releases resources associated with this object. 调用该方法后，尝试使用该对象将导致引发 ObjectDisposedException 异常。After this method has been called, an attempt to use this object will result in an ObjectDisposedException exception being thrown.
Equals(Object)

确定指定的对象是否等于当前对象。Determines whether the specified object is equal to the current object.

(继承自 Object)
Finalize()

处置对象所保留的资源。Disposes of resources the object is holding. 这是该对象的析构函数。This is the destructor for the object. 使用析构函数语法表示终结器。Finalizers are expressed using destructor syntax.
GetHashCode()

用作默认哈希函数。Serves as the default hash function.

(继承自 Object)
GetType()

获取当前实例的 Type。Gets the Type of the current instance.

(继承自 Object)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
MoveNext()

指示枚举数是否已移到了枚举中的下一个对象。Indicates whether the enumerator has moved to the next object in the enumeration.
Reset()

将枚举数重置到集合的开头。Resets the enumerator to the beginning of the collection.
ToString()

返回一个表示当前对象的 string。Returns a string that represents the current object.

(继承自 Object)

显式界面实现

IEnumerator.Current

获取集合中的当前对象。Gets the current object in the collection.
