How to get all properties and methods available for the service in PowerShell?

To display all the properties and methods available for the get-service cmdlet you need to pipeline Get-Member (alias gm). MemberType ‘Property’ is to display the specific property like machinename, servicename, etc. and with the MemberType ‘Method’ you can perform specific operations on the object, for example, Start, Stop, Pause the service, etc.
The below command is to display all the members (properties, methods) the Get-Service.
