我想使用Write-ObjectToSQL模块在SQL Server表中导入文件信息和MD5哈希。如果可能的话,我试图在一行中这样做。这就是我所拥有的:
gci -file|select Directory,Name,Extension,Length,CreationTime,LastAccessTime,LastWriteTime,@{Name='MD5'; Expression={Get-FileHash $_ -Algorithm MD5|select Hash}}|Write-ObjectToSQL -Server ABC -Database PDOC -TableName Files
我没有获得MD5列和目录列。以下是Get-Member信息:
PS C:\Users\pollusb> gci -file|select Directory,Name,Extension,Length,@{Name='MD5'; Expression={Get-FileHash $_ -Algorithm MD5|select Hash}}|gm
TypeName: Selected.System.IO.FileInfo
Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
Directory NoteProperty DirectoryInfo Directory=C:\Users\pollusb
Extension NoteProperty string Extension=.pdoc
Length NoteProperty long Length=65
MD5 NoteProperty Selected.System.Management.Automation.PSCustomObject MD5=@{Hash=C30CCC4447297D94FE10F54C18DBD5F9}
Name NoteProperty string Name=345.pdoc
因此,SQL Server将只导入非对象的NoteProperties。
现在,如果我们看一下Write-ObjectToSQL之前的内容。我删除了时间列以获得更好的结果。
PS C:\Users\pollusb> gci -file|select Directory,Name,Extension,Length,@{Name='MD5'; Expression={Get-FileHash $_ -Algorithm MD5|select Hash}} |
ft -AutoSize
Directory Name Extension Length MD5
--------- ---- --------- ------ ---
C:\Users\pollusb 345.pdoc .pdoc 65 @{Hash=C30CCC4447297D94FE10F54C18DBD5F9}
C:\Users\pollusb deletedRoute.txt .txt 51 @{Hash=DE585876A6249B9FDF176697F5D35EA4}
C:\Users\pollusb dir.txt .txt 11815 @{Hash=77F3CE7F713966D4F8E39D12E1D77947}
C:\Users\pollusb open.ps1 .ps1 116 @{Hash=F5B0126D5B0A5040BE34FDC257ADD7F4}
C:\Users\pollusb pdoc.bat .bat 34 @{Hash=E3630400A370F6D94ECE198407FDB151}
我的问题是有一种方法可以将MD5列转换为只有MD5结果而不是@ {Hash =和结束} AND来转换字符串中的Directory列吗?
答案 0 :(得分:0)
将目录名转换为字符串而不是System.IO.DirectoryInfo
,将Select Directory替换为自定义目录:
@{n='Directory'; e={$_.Directory -as [String]}}
获取文件哈希后,展开属性:
Get-FileHash $_ -Algorithm MD5 | select -ExpandProperty Hash
这将只返回实际的哈希值,而不是包含HASH属性的MD5对象。
添加新属性:
gci -file admin.bat | select @{n='Directory'; e={$_.Directory -as [String]}},
Name,
Extension,
Length,
@{Name='MD5'; Expression={Get-FileHash $_ -Algorithm MD5 | select -ExpandProperty Hash}
} | gm
它为您提供了一些String NoteProperty':
Name MemberType Definition

Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
Directory NoteProperty System.String Directory=D:\

Length NoteProperty System.Int64 Length=2901
