如何使用变量(Powershell)中文本框中的用户输入值

Question

从文本框中获取值以用于另一个函数是最困难的。如果我遍历脚本，我可以看到该值已分配给文本框，但无法将其分配给另一个变量。

以下是相关代码：

#region XMLCode
[xml]$xaml = @"

$var_txtPayrollID.Text = $global:payid
$var_txtSiteID.Text = $global:SiteNum
$var_txtFromAddress.Text = $script:from
# Get the number of daily text boxes
$global:numDailyTextBox = (Get-Variable -Name "var_txtDaily*").Count
})
$var_btnDailySend.Add_Click({
# Email contents
$body = "PeopleSoft Team,`r`nHere are the time punch files that need to be uploaded to PeopleSoft.`r`nThanks."
$sub = "cctime Files for $sitename $payrollid"
$timefiles = @()
# Run the Payroll 
$dailyTextBox = @(Get-Variable -Name "var_txtDaily*")
foreach ($textBox in $dailyTextBox) {
if ([string]::IsNullOrEmpty($textBox.Text)) {
continue
}

$date = $textBox.Text
RunDailyPayroll -day $date
LogInfo "Moving time file to C:TA"
Move-Item -Path "$script:filepath$script:dailyfile" -Destination $scriptPath -Force -Verbose

LogInfo "Email sent"
[Microsoft.VisualBasic.Interaction]::MsgBox("Email sent!", "OkOnly", "Email sent")

})

问题出现在$var_btnDailySend.Add_Click事件中。有5个文本框，用户将在其中一个或多个文本框中输入数据。然后我想在RunDailyPayroll函数中使用该值。但我不能将该值分配给另一个变量。单步执行时，值为：System.Windows.Controls.Text::<value entered>。如何将其转换为仅包含<value entered>的字符串？我试过$date = $textBox.Text.ToString()，它只是抛出一个错误。

谢谢。

您应该能够使用提取文本

$TextBox.Value.Text
