In iteration, need to store line in a variable

so, first of all my scenario: Have a file, my script reads that file, counts the number of lines and reads the content line by line.

My script:

$lines = Get-Content C:\RDS\snaps.txt | Measure-Object -Line
$line = $lines.Lines
for($i=1; $i -le ($line-1); $i++)
{
   #Need to store a line in a variable
}

I need to be in this way: For every "i" value which is less than or equal to ($line-1), I need to read the specific line.

Example: if i=1, means first line, I need to read the first line and store it in a variable. if i=($line-1), means the line above the last line, need to store that specific line and store it in the same variable.

How can this be done? I can't predict how many lines it will be there in the file. What change do I need to do in my script for this? Any help would be really appreciated.

this question is really not clear, but if you just want to read a specific line, you don't need a for loop. In fact get-content will return a collection (array) of object for each line. So the nth line can be accessed it with $content[n-1].

So 

$content=Get-Content C:\RDS\snaps.txt
$content[0] #firstline
$content[-2]# the line before the last line

You could use a simple foreach loop to iterate over each line: 

$Content = Get-Content 'C:\RDS\snaps.txt'
$lineCount = 0;
$lastLine = ''
foreach ($line in $content) 
{
    $lineCount++
    # Insert your condition to store the lastline: if ($lineCount -eq ...)
    $lastLine = $line
}
