接受multidimensional array作为参数的Powershell函数
我试图采取一个Web脚本，并使其接受一个string数组作为参数的函数。 目前我通过从同一个脚本制作两个函数来解决这个问题。 然后我使用My-Function1 -arr $1 -arr2 $2 ，之后使用My-Function2 -arr $1 -arr2 $2来解决数组问题。
要把这种types的数据传递给一个函数，必须要有一个更简洁的方法，但是在我的search中我没有看到任何东西。 我也看到了使用Tables刷新方法来运行一个新的查询，但有限的脚本经验的问题，我不知道如何使用我的脚本。
两个函数的原因是：1）第一个查询运行，结果被插入到一个新的Excel工作簿和工作表中。 2）接下来调用第二个函数来运行相同的T-SQL查询，但是这次，从＃1打开工作簿，然后插入一个新的命名工作表。

你确实可以为你想做的事情编写一个函数，但是你需要重新安排你的代码并添加一些结构。
我试图给下面的例子，你需要适应你的脚本的结构。
基本上，从我能从您发布的代码中了解到的情况，您每周都会运行特定的SQL查询，并希望将结果保存在Excel中。
在下面的例子中，我使用了for循环来确保每个数组中使用的索引是相同的。 在注释中是你需要从代码中添加的命令。
Function First-Query { param([string[]]$arr,[string[]]$arr2) #initialize Excel # do your Excel commands like opening the file, adding the workbook #Now perform the query by using the appropriate element in each array (1 query / day) for ($i = 0; $i -lt $arr.Count; $i++) { $day = $arr2[$i] $query = $arr[$i] # then add the worksheet $xlsSh.Name = $day # run the query $SqlCmd.CommandText = $query; # Save the results in the Excel columns } # Save and Quit }#End Function $arr = @() $arr += "SELECT DISTINCT" $arr += "ANOTHER QUERY SELECT DISTINCT" # additional queries added with $arr += $weekdays = @("Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday") First-Query -arr $arr -arr2 $weekdays
