比较基于版本号和其他条件的文件，并格式化输出 [英] Comparing files based on version number and some other criteria and Formatting the output

问题描述

我在Powershell中使用比较对象，根据大小，上次写入时间和版本号比较2个文件。我得到的结果。唯一的问题是如何从结果中获取版本号的值。

  function dll_compare（）{
 param（$ path1，$ path2）
 $ first = Get-ChildItem -Path $ path1 -Filter * .dll 
 $ second = Get-ChildItem -Path $ path2 -Filter * .dll 
 $ diff = Compare-Object -ReferenceObject $ first -DifferenceObject $ second -Property名称，长度，LastWriteTime，VersionInfo -PassThru |选择Name，Length，LastWriteTime，sideindicator，@ {n =path; e = {$ _。fullname}}，@ {n =VersionInfo; e = {$ _ | Select-Object -ExpandProperty VersionInfo | Select- Object -Property Productversion}} 
 $ diff} 
  

结果格式如下：我想要versioninfo包含该值，而不是@ {ProductVersion = 10.0.10240.16384}

 名称：PhotoViewer.dll 
长度：1827328 
 LastWriteTime：7/10/2015 4:31:20 PM 
 SideIndicator：< = 
路径：D：\Site1\Dlls\PhotoViewer .dll 
 VersionInfo：@ {ProductVersion = 10.0.10240.16384} 
  

解决方案

替换此行：

  $ diff = Compare-Object -ReferenceObject $ first -DifferenceObject $ second -Property名称，Length，LastWriteTime，VersionInfo -PassThru |选择Name，Length，LastWriteTime，sideindicator，@ {n =path; e = {$ _。fullname}}，@ {n =VersionInfo; e = {$ _ | Select-Object -ExpandProperty VersionInfo | Select- Object -Property Productversion} 
  

与

  $ diff = Compare-Object -ReferenceObject $ first -DifferenceObject $ second -Property名称，长度，LastWriteTime，VersionInfo -PassThru | 
选择Name，Length，LastWriteTime，sideindicator，@ {n =path; e = {$ _。fullname}}，@ {n =VersionInfo; e = {$ _。VersionInfo.Productversion} 
  

I am comparing 2 files based on size, last write time and version number using Compare-object in Powershell. I am getting the results. The only problem is how to get the value of the version number from the result.

   function dll_compare(){
   param($path1,$path2) 
   $first = Get-ChildItem -Path $path1 -Filter *.dll
   $second =  Get-ChildItem -Path $path2 -Filter *.dll
   $diff = Compare-Object -ReferenceObject $first -DifferenceObject $second -Property Name, Length, LastWriteTime, VersionInfo -PassThru  | Select Name, Length, LastWriteTime, sideindicator,@{n="path";e={$_.fullname}},@{n="VersionInfo";e={$_|Select-Object -ExpandProperty VersionInfo |Select-Object -Property Productversion}}
   $diff}

The result is in the following format: I want the versioninfo to contain the value, instead of "@{ProductVersion=10.0.10240.16384}"

Name          : PhotoViewer.dll    
Length        : 1827328    
LastWriteTime : 7/10/2015 4:31:20 PM    
SideIndicator : <=    
path          : D:\Site1\Dlls\PhotoViewer.dll    
VersionInfo   : @{ProductVersion=10.0.10240.16384}

解决方案

Replace this line:

$diff = Compare-Object -ReferenceObject $first -DifferenceObject $second -Property Name, Length, LastWriteTime, VersionInfo -PassThru  | Select Name, Length, LastWriteTime, sideindicator,@{n="path";e={$_.fullname}},@{n="VersionInfo";e={$_|Select-Object -ExpandProperty VersionInfo |Select-Object -Property Productversion}

with

$diff = Compare-Object -ReferenceObject $first -DifferenceObject $second -Property Name, Length, LastWriteTime, VersionInfo -PassThru |
    Select Name, Length, LastWriteTime, sideindicator,@{n = "path"; e ={ $_.fullname }}, @{n = "VersionInfo"; e = { $_.VersionInfo.Productversion }
