Windows Batch: write text to hosts

I want write path to my Hosts file.
I use double quote to escape whitespace.
But my output will contain double quote.
Here is my code:

setlocal EnableDelayedExpansion
CD C:\WINDOWS\System32\drivers\etc


@echo off
setlocal enabledelayedexpansion


set  arrayline[0]="119.81.166.227 test.google.com.tw"
set  arrayline[1]="119.81.166.227 test.yahoo.com.tw"


::read it using a FOR /L statement
for /l %%n in (0,1,1) do (
    (
    findstr /c:!arrayline[%%n]! hosts
    IF  ERRORLEVEL 0  echo !arrayline[%%n]! 


    )>> hosts

)
echo "complete"
pause

If I set variable like this 

set  "arrayline[0]=119.81.166.227 test.google.com.tw"

Or remove quote

set  arrayline[1]=119.81.166.227 test.yahoo.com.tw

Also will get whitespace error
How to set text to my hosts file correct?

Try like this: 

setlocal EnableDelayedExpansion
set "hosts=C:\WINDOWS\System32\drivers\etc\hosts"


@echo off
setlocal enabledelayedexpansion


set  "arrayline[0]=119.81.166.227 test.google.com.tw"
set  "arrayline[1]=119.81.166.227 test.yahoo.com.tw"


::read it using a FOR /L statement
for /l %%n in (0,1,1) do (
    findstr /c:"!arrayline[%%n]!" "%hosts%" 1>nul 2>nul || (
      (echo(!arrayline[%%n]!)>>"%hosts%" 
    )
)
echo "complete"
pause
