Powershell函数，接受多维数组作为参数

我试图让一个web脚本，并使其接受一个字符串数组作为参数的函数。目前我通过从同一个脚本中创建两个函数来解决这个问题。然后我使用My-Function1 -arr $1 -arr2 $2，然后使用My-Function2 -arr $1 -arr2 $2来解决阵列问题。Powershell函数，接受多维数组作为参数

必须有一个更简洁的方法来传递这种类型的数据只有一个功能，但在我的搜索我没有看到任何东西。我还看到了使用Tables刷新方法运行新查询的问题，但是使用我有限的脚本经验，我不确定如何将其与我的脚本一起使用。

两个函数的原因是：1）第一个查询运行并将结果插入到新的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，但这次是从＃1打开工作簿，然后插入一个新的命名工作表。

另一个有趣的结果是剩下的僵尸Excel过程。但是，打开resulant电子表格然后关闭它，Excel过程将退出。 – user4317867 2015-01-21 06:45:13

你的确可以写一个函数为你想要做什么，但你需要重新安排你的代码，并添加一些结构给它。

我试图给下面的例子一些你需要适应你的脚本的结构。

基本上，从我能够从您发布的代码中了解的情况来看，您每周都在运行特定的SQL查询并希望将结果保存在Excel中。

在下面的示例中，我使用for循环来确保每个数组中使用的索引相同。评论中是您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

看起来不错，我会努力工作并报告。谢谢！ – user4317867 2015-01-21 23:11:52

得到它的工作，不得不添加几件事情。首先，'$ xlsSh = $ xlsWb.Worksheets.Add（[System.Reflection.Missing] :: Value，$ xlsWb.Worksheets.Item（$ xlsWb.Worksheets.Count））'在最后添加新工作表。下一个'$ del = $ xlsWb.Sheets |其中{$ _。Name -eq'Sheet1'}'删除Sheet1，最后'$ activate = $ xlsWb.Sheets |其中{$ _。Name -eq'Monday'}'设置星期一（第一张）为活动状态。 – user4317867 2015-01-22 00:12:57

仅供参考，将其作为单个函数'TotalMinutes：1.74'运行，并作为双重函数'TotalMinutes：2.09'另请注意，我的'Test-Path'子句不正确。如果有人发现有帮助，它需要是'If（Test-Path $ docs）{Remove-Item $ docs}'。 – user4317867 2015-01-22 00:24:55
