GAC(64位系统)比较?

不确定您到底在追求什么,但如果要比较32位和64位GAC的程序集,请尝试以下方法:

PS> $gac64 = gci C:\Windows\assembly\GAC_64 -r *.dll | 
    select @{n='AQN';e={"$($_), $((Split-Path $_.PSParentPath -leaf) -split '__' -join ', ')"}} | 
    Sort AQN
PS> $gac32 = gci C:\Windows\assembly\GAC_32 -r *.dll | 
    select @{n='AQN';e={"$($_), $((Split-Path $_.PSParentPath -leaf) -split '__' -join ', ')"}} | 
    Sort AQN

PS> diff $gac32 $gac64 -Property AQN

AQN                                                         SideIndicator
---                                                         -------------
Mcx2Dvcs.dll, 6.1.0.0, 31bf3856ad364e35                     =>

注意,拆分并不是万无一失的(相当天真的impl),但是应该足以比较32位和64位gac之间的不同。
