MoveFilesToFolders.ps1

<#
.SYNOPSIS
    将匹配正则表达式的文件按顺序移动到对应的文件夹中

.DESCRIPTION
    此脚本会：
    1. 在指定目录中查找所有匹配文件正则表达式的文件
    2. 在指定目录中查找所有匹配文件夹正则表达式的文件夹
    3. 按名称排序后，将第n个文件移动到第n个文件夹

.PARAMETER Path
    工作目录路径（默认为当前目录）

.PARAMETER FilePattern
    匹配文件的正则表达式

.PARAMETER FolderPattern
    匹配文件夹的正则表达式

.PARAMETER WhatIf
    预览模式，只显示将要执行的操作而不实际移动

.EXAMPLE
    .\MoveFilesToFolders.ps1 -Path "D:\data" -FilePattern "^protocol_.*\.csv$" -FolderPattern "^\d{2}-\d{2}-\d{2}$"
    
.EXAMPLE
    .\MoveFilesToFolders.ps1 -Path "D:\data" -FilePattern "\.csv$" -FolderPattern "^\d{2}-\d{2}-\d{2}$" -WhatIf
