Question

我刚刚了解了Powershell GUI编程。以下代码可以成功执行，但是执行的结果不是列表中项目的文本。

像这样：

@ {Name = a1;状态=真}

@ {Name = a2;状态=假}

我需要直接输出项目的文本。

a1

a2

我尝试了很多方法，但没有结果预先感谢

Show-7_psf | Out-Null

Answer 1

更改此行

$checkedlistbox1.CheckedItems | Write-Host

收件人

$checkedlistbox1.CheckedItems.Name | Write-Host

这是因为您正在调用$csv数组中的对象，但没有选择Property，所以您将返回数组中的整个对象。

Answer 2

如果您需要任何其他属性，请替换为名称

$buttonOk_Click = {
   $checkedlistbox1.CheckedItems | Where-Object { $_."Name" | Write-Host }
}

无法直接获取所选项目
