我正在尝试创建复选框表单/弹出窗口，它使用最终将传递给该函数的PC名称列表。现在我对数组/列表进行了硬编码。我想弹出一个多重检查列表，然后根据输入运行选择的PC上的脚本。我将进行另一项测试，以表明PC是否在线并“预先”检查该PC。我在动态创建复选框时遇到问题。

答案 0 :(得分：0)
这是因为您在$checkbox循环中重新定义了foreach变量。这里有一点解释：
$checkbox = New-Object System.Windows.Forms.CheckBox
...
#at this point $checkbox becomes a string (one of your array items):
foreach($checkbox in $pcnames){
$checkBox.UseVisualStyleBackColor = $True #fails because String object doesnt have the property
...
}
您可以通过在foreach循环中使用另一个变量名来解决此问题。
这也是毫无意义的：
foreach ($checkBox in $PCNames) {
$checkBox = New-Object System.Windows.Forms.CheckBox
}
在这里，您只是为数组中的每个项重新定义$ checkbox，您应该在循环中创建它，为其分配属性
