比较两个PsCustomObjects的属性

Question

I know that I can compare the values of two PowerShell objects:

PS> $A = [PsCustomObject]@{"A"=1; "B"=$True; "C"=$False}
PS> $B = [PsCustomObject]@{"A"=1; "B"=$False; "C"=$False}
PS> Compare-Object $A $B -Property A, B, C

A  B     C SideIndicator
-  -     - -------------
1  False False =>
1  True  False <=

However, I need to compare the existance the properties of two PowerShell objects.

These objects would be considered the same:

PS> $A = [PsCustomObject]@{"A"=1; "B"=$True; "C"=$False}
PS> $B = [PsCustomObject]@{"A"=1; "B"=$False; "C"=$True}
PS> Compare-Foo $A $B
True

These objects would be considered NOT the same:

PS> $A = [PsCustomObject]@{"A"=1; "C"=$False}
PS> $B = [PsCustomObject]@{"A"=1; "B"=$False; "C"=$False}
PS> Compare-Foo $A $B
False

Is there a good way to do this?

我可以想到几种方法，最直接但未经实际测试的方法：

$A.Keys | ForEach-Object { $C = $B["$_"]; if ($C -eq "") {return $false;} }
