[网络连接] 思路征集：批处理获取本地连接的名称

Batcher

中文系统，默认是"本地连接"；英文系统，默认是"Local Area Connection"；其它语言操作系统，未知；此外，用户还可能自己修改了本地连接的名称。如何用批处理来获取本地连接的名称呢？我先抛个砖：

@echo off
rem 获取本地连接名称
rem WinXP SP2 EN 测试通过
rem WinXP SP3 CS 测试通过
reg export "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkCards" "%temp%\MyNet.reg" >nul
for /f "tokens=1 delims=:" %%a in ('type "%temp%\MyNet.reg"^|findstr /n Ethernet') do (
  set "DstRow=%%a"
  goto :next
)
goto :eof
:next
set /a SkpRow=DstRow-2
for /f "skip=%SkpRow% tokens=2 delims={}" %%a in ('type "%temp%\MyNet.reg"^|findstr .*') do (
  for /f "skip=6 tokens=*" %%b in ('reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\{%%a}\Connection"') do (
    set LcoNet=%%b
    call echo %%LcoNet:~12%%
    goto :eof
  )
)
复制代码

感谢8楼提供的测试用例！

@echo off
for /f "tokens=2 delims==" %%a in ('wmic nic get netconnectionid /value') do set "var=%%a"&call echo %%var%%&pause>nul&exit/b
复制代码

中文版系统测试通过，英文版我没有测试环境，还请BATCHER兄测试。
-----------------------------------------------
我发帖了才想起2K中貌似没有WMIC，要适用于所有系统吗？

测试BATCHER兄的代码出错：

set LcoNet=%b
call set LcoNet=%LcoNet:        =%

你的注册表里面有没有这个分支：
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\{5FBB2E38-FBE8-4F2D-908A-88FA06960529}\Connection

能否把你的本地连接所在的注册表分支贴出来看看？应该在这个下面的其中一个：
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\

这是我的注册表信息，能找到本地连接，但不在{5FBB2E38-FBE8-4F2D-908A-88FA06960529}这个项里。

reg export导出的"%temp%\MyNet.reg"里面有没有{5D4BF871-B3AC-4806-869C-B859C0B73BC3}？
第一个for命令有没有正确的把{5D4BF871-B3AC-4806-869C-B859C0B73BC3}所在行赋值给变量DstRow？

知道原因了，双网卡。修改一下第一个for命令就行了，我稍后在顶楼更新。

@echo off

:GetName
set "str=%1"
set LocalConn_%2=%str:~18,-1%

然后怎么确定哪个是呢？

嘿嘿，你在顶楼不是说了吗：英文系统，默认是"Local Area Connection"；^_^

关键是后面那句“此外，用户还可能自己修改了本地连接的名称。”
