Creating Variables From Text File

Question

Hello a little new to powershell and have banging my head on the wall trying to get this working.
I have a text file (where the numbers of lines will change everytime) that will contain AD groups. 
Lets say it looks like this
GroupA
GroupB
GroupC
I'm trying to you a loop that will read the file and output each new line to a variable so
var1=GroupA
Var2 =GroupB
Var3=Groupc
My first problem is that non of these can be null since this will be then be used with Add-ADgroupmemeber
So I have it get the number of items with $Items = get-content *File* | Measure-Object -Line
After that I have been trying to use a loop which to me looks like it should work however is not. I'm not getting any errors. However I'm not getting any created variables either. 
For ($i=1; $i -lt $Items.lines; $i++) {
$var[$i] = (Get-Content *File*)[$i-1]
write-host $var[$i]}
In my head I should get a listed of each line of the txt file but I'm getting nothing. 
In the end I was hoping to doing something along the lines of ADD-Adgroupmember -identity $Var[$i] -members *Machine Name*
If there is a better way to approach this I'm all ears.
Thanks for any help!

You don't need a loop to read each line from the file. You don't need a variable for each group read from the file. 
For example, if your file looks like:
GroupA
GroupB
GroupC
with spaces/empty lines in it, that you wish to ignore, you can use:
$Groups = Get-Content .\groups2.txt | % { ($_.split(" ",[System.StringSplitOptions]::RemoveEmptyEntries)) }
The $Groups variable will be an array that holds non-empty lines from the file. You can use that directly as in:
foreach ($Group in (Get-Content .\groups2.txt | % { ($_.split(" ",[System.StringSplitOptions]::RemoveEmptyEntries)) })) {
Add-ADGroupMember -identity $Group -members *Machine Name*
