Question

我有以下代码，试图在其中找到与一天中特定时间有关的值。我在if语句中使用以下for循环。

我已经尝试过，但是对if（条件？）逻辑感到困惑

$currentTime = Get-Date -Format "HH:mm"
$poolProfileWorkdayArray: [
          {
            "time": "00:02",
            "hotAmount": 1,
            "coldAmount": 1
          },
          {
            "time": "05:00",
            "hotAmount": 2,
            "coldAmount": 2
          },
          {
            "time": "09:00",
            "hotAmount": 3,
            "coldAmount": 3
          },
          {
            "time": "14:21",
            "hotAmount": 4,
            "coldAmount": 4
          }
        ]


--------------------------------------------------

for ($i = 0; $i -lt $($poolProfileWorkdayArray.count); $i++) { 

       Write-Output "test for $i : $($poolProfileWorkdayArray[$i])"

     if (($currentTime -ge $poolProfileWorkdayArray[$i - 1]) -and ($currentTime -le $poolProfileWorkdayArray[$i])) {

       Write-Output $poolProfileWorkdayArray[$i - 1]
       $customImageColdVmAmount = $poolProfileWorkdayArray[$i - 1].coldAmount

Write-Output "Cold amount for custom weekDay is : $poolProfileWorkdayArray[$i-1].coldAmount)"

                            break
                        }
                    }

我正在寻找的是，它将遍历循环并检查是数组值与$ customImageColdVmAmount值之间的当前时间。我尝试了一下，发现当前时间是17.30，它不起作用，也不是$ customImageColdVmAmount中的值。如果这里的条件合适，那该怎么办？

我对您的代码进行了一些更正。但是，对于您的预期输出用例，我可能不清楚，但是您的意思是这个意思。

($currentTime = Get-Date -Format "HH:mm")

# Results

<#
17:39
#>

 $poolProfileWorkdayArray = @'
[
    {
        "time": "00:02",
        "hotAmount": 1,
        "coldAmount": 1
    },
    {
        "time": "05:00",
        "hotAmount": 2,
        "coldAmount": 2
    },
    {
        "time": "09:00",
        "hotAmount": 3,
        "coldAmount": 3
    },
    {
        "time": "18:21",
        "hotAmount": 4,
        "coldAmount": 4
    }
]
'@

($WorkDayArray = $poolProfileWorkdayArray | ConvertFrom-Json)

# Results
<#
time  hotAmount coldAmount
----  --------- ----------
00:02         1          1
05:00         2          2
09:00         3          3
18:21         4          4
#>



 for ($i = 0; $i -lt $($WorkDayArray.count); $i++) 
{ 
    "test for $i : $($WorkDayArray.time[$i])"

    if (($currentTime -ge $WorkDayArray.time[$i - 1]) -and ($currentTime -le $WorkDayArray.time[$i])) 
    {
        $WorkDayArray[$i - 1]
        $customImageColdVmAmount = $WorkDayArray[$i - 1].coldAmount

        "Cold amount for custom weekDay is : $($WorkDayArray[$i-1].coldAmount)"

        break
    }
}

# Results
<#
test for 0 : 00:02
test for 1 : 05:00
test for 2 : 09:00
test for 3 : 18:21

time  hotAmount coldAmount
----  --------- ----------
09:00         3          3
Cold amount for custom weekDay is : 3
