我看到一些奇怪的行为。在我的机器上,PowerShell 返回记录集,我可以遍历记录没有问题。在我同事的机器上(他有权访问我需要从中复制文件的文件共享)正在返回一个记录计数而不是实际记录。我一定错过了一些简单的东西。知道为什么我会看到这种不同的行为吗?
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = server; Database = db; Integrated Security = True"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "SELECT fileName from SomeTable"
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$Table = new-object data.datatable
$Table = $DataSet.tables[0]
$SqlConnection.Close()
function Out-FileForce {
PARAM($path)
PROCESS
{
if(Test-Path $path)
{
Out-File -inputObject $_ -append -filepath $path
}
else
{
new-item -force -path $path -value $_ -type file
}
}
}
foreach ($Row in $Table.Rows)
{
$fullPath = $Row.FullFilePathWithName
$path = "\\server\folder\"
$newPath = "C:\newFolder\"
$newDestination = $fullPath -replace [regex]::Escape($path), $newPath
#Write-Output $newDestination
#Write-Output $fullPath
# recurse should force the creation of the folder structure
#Copy-Item $fullPath $newDestination -recurse
Out-FileForce $newDestination
Copy-Item $fullPath $newDestination -force
Write-Output $newDestination " done"
}
