How to count objects in PowerShell?

As I'm reading in the PowerShell user guide, one of the core PowerShell concepts is that commands accept and return objects instead of text. So for example, running get-alias returns me a number of System.Management.Automation.AliasInfo objects:

PS Z:\> get-alias

CommandType     Name                                             Definition
-----------     ----                                             ----------
Alias           %                                                ForEach-Object
Alias           ?                                                Where-Object
Alias           ac                                               Add-Content
Alias           asnp                                             Add-PSSnapIn
Alias           cat                                              Get-Content
Alias           cd                                               Set-Location
Alias           chdir                                            Set-Location
...

Now, how do I get the count of these objects?

in my exchange the cmd-let you presented did not work, the answer was null, so I had to make a little correction and worked fine for me:

@(get-transportservice | get-messagetrackinglog -Resultsize unlimited -Start "MM/DD/AAAA HH:MM" -End "MM/DD/AAAA HH:MM" -recipients "user@domain.com" | where {$_.Event
ID -eq "DELIVER"}).count

Get-Alias|ForEach-Object {$myCount++};$myCount

158
