Get SCCM COllection Members

I got a task to create a script so other team could use it to retrieve the list of machines from specific collection in SCCM.

<#
.Synopsis
   This script query specific sccm collection and list all its members


.DESCRIPTION
   This powershell script is designed to get list of all devices from a specific collection in SCCM, and it saves the output to a text file in c:\device.txt
   Path:
         by default it saves the output to "c:\device.txt". you can change the path to your specific location, just change the $path parameter value
   Collection:
        The default collection is "workstations" 
        To use specific Collection, first you need to find the Collection ID from sccm console like "SF1003", then change the value of paramater in script  "[string]$SCCMCollectionID = 'SF1003' "


.EXAMPLE
	You can run the script first so it could be saved in current session memory, then call the function using dot source as:
    . .\Get_Sccm_Collection_members_PS.ps1  
  	Get-CollectionMembership

.EXAMPLE
   You can call the script directly
  .\Get_Sccm_Collection_members_PS.ps1  

.EXAMPLE
   To override the default paramters value with different info, use this 
   .\Get_Sccm_Collection_members_PS.ps1  -siteCode 'sitecode' -siteserver 'servername' -collectionID 'collection id' -path 'c:\device.txt" 
   

.EXAMPLE
   To override the default paramters value with different info, use this 
    . .\Get_Sccm_Collection_members_PS.ps1  
    Get-CollectionMembership-siteCode 'sitecode' -siteserver 'servername' -collectionID 'collection id' -path 'c:\device.txt"
