我想根据数据确定需要选择的文件夹，然后，如果找不到它，它将显示GUI等待并循环执行检查。我尝试使用此代码，可以找到该文件夹，但是当我想显示GUI时找不到它时，它将返回一些错误。
这就是我检查文件夹的方式
function FIND {
Write-Host "call the function that can call the GUI.ps1 script"
$Path = "D:\Process"
Write-Host "Starting Mapping SSID and Finding Job"
$SSID_Unit = "111dddddfafafesa"
Try{
$Path_Job = (Get-Item (Get-ChildItem "$Path\*\SSID_LST" | Select-String -Pattern "$SSID_Unit").Path).Directory.FullName
$global:Result = [PSCustomObject]@{
Exists = $true
FileName = $Path_Job.FullName
Attempts = 1
}
Write-Host "Job'$($global:Result.FileName)' Exists. Found after $($global:Result.Attempts) attempts." -ForegroundColor Green
Write-Host "Continue to Assigned Job"
Pause
} Catch {
Write-Host "Waiting for the jobss"
& D:\X\Wait_GUI.ps1 -Path $Path_Job -MaxAttempts 20
Write-Host "Job not found after $($global:Result.Attempts) attempts." -ForegroundColor Red
}
}
FIND
这是GUI

如果找不到，则返回此
Waiting for the jobss
Job not found after 1 attempts.
并且未显示GUI
答案 0 :(得分：4)
好吧，首先，您正在代码和GUI中对文件和/或目录使用不同的测试。此外，您使用设置为$null值的路径调用GUI.ps1文件。
我会将您的代码更改为以下内容：
$Path = "D:\Process\*\SSID_LST\*" # the path to look for files
$SSID_Unit = "111dddddfafafesa" # the Search pattern to look for inside the files
function Test-FileWithGui {
[CmdletBinding()]
param(
[Parameter(Mandatory = $true, Position = 0)]
[string]$Path,
[Parameter(Mandatory = $true, Position = 2)]
[string]$Pattern,
[int]$MaxAttempts = 5
)
Write-Host "Starting Mapping SSID and Finding Job"
# set up an 'empty' $global:Result object to return on failure
$global:Result = '' | Select-Object @{Name = 'Exists'; Expression = {$false}}, FileName, Directory, @{Name = 'Attempts'; Expression = {1}}
# test if the given path is valid. If not, exit the function
if (!(Test-Path -Path $Path -PathType Container)) {
Write-Warning "Path '$Path' does not exist."
return
}
# try and find the first file that contains your search pattern
$file = Select-String -Path $Path -Pattern $Pattern -SimpleMatch -ErrorAction SilentlyContinue | Select-Object -First 1
if ($file) {
$file = Get-Item -Path $file.Path
$global:Result = [PSCustomObject]@{
Exists = $true
FileName = $file.FullName
Directory = $file.DirectoryName
Attempts = 1
}
}
else {
& "D:\GUI.ps1" -Path $Path -Pattern $Pattern -MaxAttempts $MaxAttempts
}
}
# call the function that can call the GUI.ps1 script
Test-FileWithGui -Path $Path -Pattern $SSID_Unit -MaxAttempts 20
# show the $global:Result object with all properties
$global:Result | Format-List
# check the Global result object
if ($global:Result.Exists) {
Write-Host "File '$($global:Result.FileName)' Exists. Found after $($global:Result.Attempts) attempts." -ForegroundColor Green
}
else {
Write-Host "File not found after $($global:Result.Attempts) attempts." -ForegroundColor Red
}
接下来是GUI文件。
现在，当您搜索包含一些文本的文件时，您需要第三个参数来调用名为Pattern的文件。
在GUI文件中，我们使用参数$Pattern作为搜索字符串，执行与上述代码完全相同的测试：
Param (
[string]$Path,
[string]$Pattern,
[int]$MaxAttempts = 5
)
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()
# set things up for the timer
$script:nAttempts = 0
$timer = New-Object System.Windows.Forms.Timer
$timer.Interval = 1000 # 1 second
$timer.Add_Tick({
$global:Result = $null
$script:nAttempts++
# use the same test as you did outside of the GUI
# try and find the first file that contains your search pattern
$file = Select-String -Path $Path -Pattern $Pattern -SimpleMatch -ErrorAction SilentlyContinue | Select-Object -First 1
if ($file) {
$file = Get-Item -Path $file.Path
$global:Result = [PSCustomObject]@{
Exists = $true
FileName = $file.FullName
Directory = $file.DirectoryName
Attempts = $script:nAttempts
}
$timer.Dispose()
$Form.Close()
}
elseif ($script:nAttempts -ge $MaxAttempts) {
$global:Result = [PSCustomObject]@{
Exists = $false
FileName = $null
Directory = $null
Attempts = $script:nAttempts
}
$script:nAttempts = 0
$timer.Dispose()
$Form.Close()
}
})
$Form = New-Object system.Windows.Forms.Form
$Form.ClientSize = '617,418'
$Form.Text = "AutoGM"
$Form.BackColor = "#8b572a"
$Form.TopMost = $true
$Form.WindowState = 'Maximized'
# I have removed $Label2 because it is easier to use
# just one label here and Dock it to Fill.
$Label1 = New-Object system.Windows.Forms.Label
$Label1.Text = "UNDER AUTOMATION PROCESS`r`n`r`nWaiting for the job..."
$Label1.AutoSize = $false
$Label1.Dock = 'Fill'
$Label1.TextAlign = "MiddleCenter"
$Label1.ForeColor = "#ffffff"
$L_S = (($Form.Width/2) - ($Form.Height / 2)) / 10
$Label1.Font = "Microsoft Sans Serif, $L_S, style=Bold"
$Form.controls.Add($Label1)
# start the timer as soon as the dialog is visible
$Form.Add_Shown({ $timer.Start() })
[void]$Form.ShowDialog()
# clean up when done
$Form.Dispose()
测试期间的结果如下所示
如果在集合MaxAttempts中找到了该文件，则尝试：
Starting Mapping SSID and Finding Job Exists : True FileName : D:\Process\test\SSID_LST\blah.txt Directory : D:\Process\test\SSID_LST Attempts : 7 File 'D:\Process\test\SSID_LST\blah.txt' Exists. Found after 7 attempts.
找不到文件时：
Starting Mapping SSID and Finding Job Exists : False FileName : Directory : Attempts : 20 File not found after 20 attempts.
如果甚至找不到文件夹$Path，则输出为
Starting Mapping SSID and Finding Job WARNING: Path 'D:\Process\*\SSID_LST\*' does not exist. Exists : False FileName : Directory : Attempts : 1 File not found after 1 attempts.
希望有帮助
