In PowerShell I have an array of string objects, and I have an object that contains string objects. In Java you can do a .equals(aObject) to test if the string values match, whereas doing a == test if the two objects refer to the same location in memory.
How do I run an equivalent .equals(aObject) in powershell?
I'm doing this:
$arrayOfStrings[0].Title -matches $myObject.item(0).Title
These both have the exact same string values, but I get a return value of false. Any suggestions?
You want to do $arrayOfString[0].Title -eq $myPbiject.item(0).Title
-match is for regex matching ( the second argument is a regex )
You can do it in two different ways.
Option 1: The -eq operator
>$a = "is"
>$b = "fission"
>$c = "is"
>$a -eq $c
True
>$a -eq $b
False
Option 2: The .Equals() method of the string object. Because strings in PowerShell are .Net System.String objects, any method of that object can be called directly.
>$a.equals($b)
False
>$a.equals($c)
True
>$a|get-member -membertype method
List of System.String methods follows.
