Question: In PowerShell, how do you convert an array value into an integer value?
Answer: Assuming that the value is an integer (e.g., not value that is legal for an array but not an integer), do the following:
1. Write the array value to a file.
2. Use the key word trim to eliminate blank space or other characters that would not be supported by the integer data type.
3. Read the resulting value into a variable (e.g., $a) and convert the value to a string.
4. Use [int] and [convert] terms:
[int]$newa = [convert]::ToInt32($a)
