The .NET property types Property, Method and Events
In most cases, a PowerShell object (which is an instance of
System.Management.Automation.PSObject) wraps a
.NET object (See also the
Extended Type System). The members of the underlying .NET object have one of the object types
Method,
Property or
Event. These are marked with a ✓ in the last column of the first table.
Members with another member type are added to the PowerShell object and are independent from the underlying .NET object.
Such members can be added with the
add-member cmdLet. (See especially the
-memberType option of that cmdLet).
