Question

我来自美国国外，我非常喜欢Netflix。这就是我坚持一键更改DNS的原因。我写了一些代码，但它不起作用，我不知道，为什么它没有。这是：

`Echo On
IF netsh interface ipv4 set dnsserver "Wi-Fi" source=dhcp==netsh interface ipv4 set dnsserver "Wi-Fi" source=dhcp DO (
netsh interface ipv4 add dnsserver "Wi-Fi" 123.123.123.123
netsh interface ipv4 add dnsserver "Wi-Fi" 123.123.123.124 index=2
ECHO DNS has changed to specific.
)
ELSE (
netsh interface ipv4 set dnsserver "Wi-Fi" source=dhcp
ECHO DNS has changed to automatic.
)
ipconfig /flushdns
`

即使无法检查错误，因为cmd会自动退出。每个命令都有效，所以我搞砸了＆＃34;如果＆＃34;？帮助将不胜感激＆lt; 3

Answer 1

IF "netsh interface ipv4 set dnsserver "Wi-Fi" source=dhcp" == "netsh interface ipv4 set dnsserver "Wi-Fi" source=dhcp" (

a）如果可能有空格，请将您的字符串括在qoutes中。

b）DO

没有if

c）)和ELSE以及(必须位于同一物理线路上：

) else (

Answer 2

我很喜欢我的问题，多亏了你，我得到了解决方案。我使用文件比较命令以我想象的方式执行此操作。这是：

@echo off
REM At first, define an interface you're using by command "netsh interface ipv4 show dnsserver".
REM Depends on language the names could be diffrent.
REM Example: Wireless Network Connection / Local Area Connection / Wi-Fi

set INTERFACE=Wi-Fi
set DNS1=123.123.123.123
set DNS2=123.123.123.124

REM Here we goes:
netsh interface ipv4 show dnsserver "%INTERFACE%" > C:\DNS.txt
fc /b DNS.txt DNX.txt > nul
IF errorlevel 1 (
netsh interface ipv4 set dnsserver "%INTERFACE%" source=dhcp
ECHO DNS has changed to automatic. 
ECHO.
) else (
netsh interface ipv4 add dnsserver "%INTERFACE%" %DNS1%
netsh interface ipv4 add dnsserver "%INTERFACE%" %DNS2% index=2
ECHO DNS has changed to static. 
ECHO.
)
ipconfig /flushdns > nul
netsh interface ipv4 show dnsserver "%INTERFACE%" > DNX.txt
pause

似乎工作了:)再次感谢您的帮助：）
