如何在Golang中使用COM（组件对象模型）

I have a Windows DLL (XA_Session.dll) file but I don't know how to use it in golang.

This is a DLL Viewer picture

ConnectServer

Here is my code

package main

import (
    "syscall"
    "fmt"
)

var (
    mod = syscall.NewLazyDLL("XA_Session.dll")
    proc = mod.NewProc("DllGetClassObject")
)

func main() {
    var bConnect bool
    bConnect = proc.ConnectServer("hts.ebestsec.co.kr", 20001)

    if bConnect {
        fmt.Println("Success")
    } else {
        fmt.Println("Fail")
    }
}

compile error:

.\main.go:17: proc.ConnectServer undefined (type *syscall.LazyProc has no field or method ConnectServer)
