与 Powershell 交换 - 奇怪的错误

Question

我输入了我的代码，但出现错误。代码运行很好，在我尝试添加保管箱功能之前，我能够将其设置为运行。我似乎无法弄清楚这有什么问题...

Answer 1

这可能有点误导，但错误是说它不知道如何对 $return[0] 对象使用 + 运算符。例如，字符串和整数可以与 + 运算符一起使用。

您错过了复制整个错误。考虑以下代码。我将尝试错误地将 space 添加到文件夹名称对象。

$folder = Get-Item "C:\temp"
$folder + " "

Method invocation failed because [System.IO.DirectoryInfo] doesn't contain a method named 'op_Addition'.
At line:2 char:1
+ $folder + " "
+ ~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (op_Addition:String) [], RuntimeException
    + FullyQualifiedErrorId : MethodNotFound

op_Addition 是在您的 post 中被截断的文本。

您的实际问题

即使您有一个 return 语句，函数也会 return 所有输出回输出流。您需要将该额外输出通过管道传递给 null。铸造到 [void] 或管道到 Out-Null 是两种常见的方法。

这些行是实际问题

[System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") 
[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")

需要通过管道将输出设为空/无效。（我从编辑中看到你已经明白了这一点。）

[void]([System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms"))
[void]([System.Reflection.Assembly]::LoadWithPartialName("System.Drawing"))

如果我运行这段代码工作正常。有没有人有办法在表单中输入下拉框？

Answer 3

我收到了同样的错误消息，但这是因为代码中的错误：

$NUFirstname =  $mTextBox1
$NULastname  =  $mTextBox2

应该是：

$NUFirstname =  $mTextBox1.text
$NULastname  =  $mTextBox2.text
