将小的 PS 脚本转换为 .BATch 文件中的长行

Question

我有这个 PowerShell 代码，是从这个问题的答案中得到的；它显示了运行 PS 代码的 cmd.exe 窗口的位置/尺寸：

$WindowFunction,$RectangleStruct = Add-Type -MemberDefinition @'
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);
[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
    public int Left;
    public int Top;
    public int Right;
    public int Bottom;
}
'@ -Name "type$([guid]::NewGuid() -replace '-')" -PassThru

$MyWindowHandle = (Get-Process -Id (Get-WmiObject Win32_Process -Filter "ProcessId=$PID").ParentProcessId).MainWindowHandle

$WindowRect = New-Object -TypeName $RectangleStruct.FullName
$null = $WindowFunction::GetWindowRect($MyWindowHandle,[ref]$WindowRect)

Write-Host $WindowRect.Left $WindowRect.Top $WindowRect.Right $WindowRect.Bottom

当我从命令行在 .ps1 脚本中运行此代码时，它可以正常工作：

C:\Users\Antonio\Documents\test> powershell Set-ExecutionPolicy -ExecutionPolicy
Unrestricted -Scope Process; .\test.ps1
26 -7 943 738

我想将此代码插入到 .BATch 文件中，以便没有单独的 .ps1 文件，因此我必须在长行中编写相同的代码作为powershell命令的参数。但是，为了保持可读性，我想在 .bat 文件中使用单独的行，并用 Batch 继续符终止每一行^；这是我的第一次尝试：

@echo off

PowerShell  ^
   $WindowFunction,$RectangleStruct = Add-Type -MemberDefinition '^
   [DllImport("user32.dll", SetLastError = true)]  ^
   [return: MarshalAs(UnmanagedType.Bool)]  ^
   public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);  ^
   [StructLayout(LayoutKind.Sequential)]  ^
   public struct RECT  ^
   {  ^
      public int Left;  ^
      public int Top;  ^
      public int Right;  ^
      public int Bottom;  ^
   }  ^
   ' -Name "type$([guid]::NewGuid() -replace '-')" -PassThru;  ^
   $MyWindowHandle = (Get-Process -Id (Get-WmiObject Win32_Process -Filter "ProcessId=$PID").ParentProcessId).MainWindowHandle;  ^
   $WindowRect = New-Object -TypeName $RectangleStruct.FullName;  ^
   $null = $WindowFunction::GetWindowRect($MyWindowHandle,[ref]$WindowRect);  ^
   Write-Host $WindowRect.Left $WindowRect.Top $WindowRect.Right $WindowRect.Bottom
%End PowerShell%

当我运行这个批处理文件时，报告了几个错误：

C:\Users\Antonio\Documents\test> test.bat
Add-Type : c:\Users\Antonio\AppData\Local\Temp\yhd4ckqv.0.cs(8) : El nombre

and a long et cetera....

我试图将撇号传递给下面的行，通过引号更改撇号，反之亦然，消除了每行开头的额外空格和其他一些修改，但我找不到编写此代码的正确方法。我之前用同样的方式写了几个比这个大得多的 PS 代码段，完全没有问题。虽然我是一名经验丰富的程序员，但我对 PowerShell 还是新手，它的多种特性一直让我感到困惑......

在批处理文件中编写此 PS 代码的正确方法是什么？如果还包括对问题原因的简单解释，我将不胜感激...

双引号文字必须转义为 \"
