PowerShell 多个 IF 语句和 ForEach 循环

Question

我很难理解为什么下面的脚本在到达第二个 ForEach/IF 语句时会失败。

Multiple ForEach/IF

谁能解释一下为什么这不起作用？以及如何在同一个脚本中使用多个独立的 If 语句和一个操作？

#Get the SharePoint list contents
$listItems= (Get-PnPListItem -List $ListName -Fields "Title","InquestTwoDate", "InquestThreeDate" -PageSize 1000) 

#Iterate through each item in the List and set date to null
ForEach ($listItem in $listItems)
{
If($listItem[“InquestTwoDate”] -eq "$date")
    {    
        Set-PnPListItem -List $ListName -Identity $listItem -Values @{“InquestTwoDate”=$null}
        #Write-Host $listItem[“InquestTwoDate”]
    }
    }
#Iterate through each item in the List and set date to null
ForEach ($listItem in $listItems)
{
If($listItem[“InquestThreeDate”] -eq "$date")
    {    
        Set-PnPListItem -List $ListName -Identity $listItem -Values @{“InquestThreeDate”=$null}
        #Write-Host $listItem[“InquestThreeDate”]
    }
    }

您应该改用常规双引号：["InquestTwoDate"]
