求助一段 操作WMI代码

//这段网上复制来的 看起来有点像 估计改下可以实现我要的功能 不太看得懂 求助 希望帮改改下
//这个是一段 利用WMI获取当前Windows下进程的演示代码
//【如果可以 可以给个红包意思意思辛苦费嘻嘻！】
package main

import (
        "github.com/mattn/go-ole"
        "github.com/mattn/go-ole/oleutil"
)

func main() {
    // init COM, oh yeah
    ole.CoInitialize(0)
    defer ole.CoUninitialize()

    unknown, _ := oleutil.CreateObject("WbemScripting.SWbemLocator")
    defer unknown.Release()

    wmi, _ := unknown.QueryInterface(ole.IID_IDispatch)
    defer wmi.Release()

    // service is a SWbemServices
    serviceRaw, _ := oleutil.CallMethod(wmi, "ConnectServer")
    service := serviceRaw.ToIDispatch()
    defer service.Release()

    // result is a SWBemObjectSet
    resultRaw, _ := oleutil.CallMethod(service, "ExecQuery", "SELECT * FROM Win32_Process")
    result := resultRaw.ToIDispatch()
    defer result.Release()

    countVar, _ := oleutil.GetProperty(result, "Count")
    count := int(countVar.Val)

    for i :=0; i < count; i++ {
        // item is a SWbemObject, but really a Win32_Process
        itemRaw, _ := oleutil.CallMethod(result, "ItemIndex", i)
        item := itemRaw.ToIDispatch()
        defer item.Release()

        asString, _ := oleutil.GetProperty(item, "Name")

        println(asString.ToString())
    }
}

改这样的例子
这是一段 powershell的代码
$getWMi = gwmi -n root\wmi -cl testData
$serverID = $getWMi.AddSession("test_Init") 
$Getsession = gwmi -n root\wmi -q "select * from test where SessionId=$($serverID.SessionId)" 
$output = $Getsession.GetValue("data/yu").value
echo "$output"
