如何从对象中的项目中获取值？

Question

我有以下代码和查询以从 Wlan 连接获取 Sent/Received 字节。我想获取每个属性项的值，但在尝试这样时我得到 Generic failure：

a = WMIvalues.Item(1).Properties_.Item(1).Value

正确的做法是什么？

 Sub Test()
    Dim WMIvalues As Object
    Dim sWQL      As String


    sWQL = "Select BytesReceivedPersec,BytesSentPersec,BytesTotalPersec  from  Win32_PerfRawData_Tcpip_NetworkInterface"

    Set WMIvalues = GetObject("winmgmts:root/CIMV2").ExecQuery(sWQL)

    a = WMIvalues.Item(1).Properties_.Item(1).Value

End Sub

Answer 1

这对我有用：

Dim WMIvalues As Object
Dim sWQL      As String
Dim o As Object, i As Long

sWQL = "Select BytesReceivedPersec,BytesSentPersec,BytesTotalPersec  from  " _
        "Win32_PerfRawData_Tcpip_NetworkInterface"

Set WMIvalues = GetObject("winmgmts:root/CIMV2").ExecQuery(sWQL)

i = 0
For Each o In WMIvalues
    i = i + 1 'increment item counter variable
    Debug.Print o.BytesReceivedPersec, o.BytesSentPersec, o.BytesSentPersec, o.BytesTotalPersec

    'logic here based on i and the o properties...
Next o
