如何在变量中使用用户从文本框中输入的值Powershell

如何解决如何在变量中使用用户从文本框中输入的值Powershell

我最难从文本框中获取值以用于其他功能。如果我逐步执行脚本，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：

问题出在$var_btnDailySend.Add_Click事件中。有5个文本框，用户将在其中输入数据到一个或多个文本框中。然后，我想在RunDailyPayroll函数中使用该值。但是我不能将该值分配给另一个变量。逐步执行时，值为：System.Windows.Controls.Text::<value entered>。如何将其转换为仅<value entered>的字符串？而且我已经尝试过$date = $textBox.Text.ToString()，它只会引发错误。

谢谢。

解决方法

您应该能够使用

提取文本

$TextBox.Value.Text
