Passing Hashes to a Powershell function problem

Question

I must be missing something. i have to variables: $var1 and $var2

$var1 | gm 
 TypeName: System.Collections.Hashtable

Each of them has IP and Por

Answer 1

I've had problems with my functions when calling them with parenthesis. Have you tried calling your function like so?

    CompareData -data1 $var1 -data2 $var2

Answer 2

When you use parentheses, PowerShell constructs an array with all the values in it, and uses that as the value for one parameter.

So, CompareData ($var1, $var2) is equivalent to CompareData -data1 @($var1, $var2) with no value specified for the -data2 parameter.

If you use CompareData -data1 $var1 -data2 $var2 as suggested by @dwillits you should get the result you expect.
