Powershell - 删除两个变量之间的空格

Question

I have two array's which contain a selection of strings with information taken from a text file. I then use a For Loop to loop through both arrays and print out the strings together, which happen to create a folder destination and file name.

Get-Content .\PostBackupCheck-TextFile.txt | ForEach-Object { $a = $_ -split ' ' ; $locationArray += "$($a[0]):\$($a[1])\" ; $imageArray += "$($a[2])_$($a[3])_VOL_b00$($a[4])_i000.spi" }

The above takes a text file, splits it into separate parts, stores some into the locationArray and other information in the imageArray , like this:

locationArray[0] would be L:\\Place\\

imageArray[0] would be SERVERNAME_C_VOL_b001_i005.spi

Then I run a For Loop:

for ($i=0; $i -le $imageArray.Length - 1; $i++) 
    {Write-Host $locationArray[$i]$imageArray[$i]}

But it places a space between the L:\\Place\\ and the SERVERNAME_C_VOL_b001_i005.spi

So it becomes: L:\\Place\\ SERVERNAME_C_VOL_b001_i005.spi

Instead, it should be: L:\\Place\\SERVERNAME_C_VOL_b001_i005.spi

How can I fix it?

Answer 1

Option #1 - for best readability:

{Write-Host ("{0}{1}" -f $locationArray[$i], $imageArray[$i]) }

Option #2 - slightly confusing, less readable:

{Write-Host "$($locationArray[$i])$($imageArray[$i])" }

Option #3 - more readable than #2, but more lines:

{
  $location = $locationArray[$i];
  $image = $imageArray[$i];
  Write-Host "$location$image";
}
