以下代码仅限一块网卡的机器，多块网卡的代码需要调整
以管理员身份powershell执行这几句命令
$gw=(Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'").defaultipgateway
#$idx=(Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'").InterfaceIndex
$idx=(Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'" | Where-Object {$_.servicename -eq "netkvm"} ).InterfaceIndex
下面这些开头带#的是备忘的，不用管，跳过即可
#$idx=(Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'" | Where-Object {$_.Description -notmatch "NGN"} ).InterfaceIndex
#$idx=(Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'" | Where-Object {$_.Description -match "Tencent"} ).InterfaceIndex
#win32-networkadapter、win32-networkadapterconfiguration 的数据结构有一部分属性是一样的，但win32-networkadapterconfiguration的数据结构里没有NetConnectionID，win32-networkadapter的数据结构里才有NetConnectionID
$interfacename=Get-WmiObject Win32_NetworkAdapter -Filter 'NetEnabled=True' | Select -ExpandProperty NetConnectionID
#$interfacename=(((netsh interface show interface)[3] -replace ' ', ';') -replace ';;;', '').split(";")[-1].trim(" ") 如果主网卡名称前面有空格，这空格也是网卡name的一部分，这句代码输出的结果会自动剔除网卡名称左边的空格，结果不准确，因此注释这句，之所以添到这里，是记录下练习语法的过程，如果网卡名称前面没有空格，这句代码至少还是在没有借助$idx的情况下起作用的嘛
#$interfacename=(Get-NetAdapter -InterfaceIndex $idx).Name 需要借助$idx，不如上面黑体那句来得直接，因此注释
route delete 0.0.0.0 mask 0.0.0.0 2>$null
route add 0.0.0.0 mask 0.0.0.0 $gw metric 1 IF $idx 2>$null
route add -p 0.0.0.0 mask 0.0.0.0 $gw metric 1 IF $idx 2>$null
最后两句根据需求而定
netsh interface set interface $interfacename disabled
netsh interface set interface $interfacename enabled

这句代码可以获取本地连接名称，通用中英文版2008R2-2022系统（含Win7-Win11)
代码语言：javascript复制(Get-WmiObject Win32_NetworkAdapter -Filter 'NetEnabled=True').NetConnectionID下面这句适用2012-2022(Win8-Win11)
代码语言：javascript复制(Get-NetAdapter).name
