try-catch

I'm writing a script and want to control the errors. However im having trouble finding information on error handling using the try, catch. I want to catch the specific error (shown below) and then perform some actions and resume the code. What code is needed for this?

This is the code i am running and im entering in a invalid username when prompted.

Get-WMIObject Win32_Service -ComputerName localhost -Credential (Get-Credential)



Get-WmiObject : User credentials cannot be used for local connections 
At C:\Users\alex.kelly\AppData\Local\Temp\a3f819b4-4321-4743-acb5-0183dff88462.ps1:2 char:16
+         Get-WMIObject <<<<  Win32_Service -ComputerName localhost -Credential (Get-Credential)
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand
