如何使用 powershell 排除周末和节假日

Question

我正在尝试在 PowerShell 中编写代码以排除周末和节假日，但出现错误，你能帮我解决这个问题吗？

$a = Get-Date -format "yyyy-MM-dd"
#Get-Date -format "dddd yyyy-MM-dd"

if($a.DayOfWeek -eq 'Tuesday')
{
    Write-Host "tuesday"
}
else
{
    Write-Host "false"
}

Answer 1

It is recommended to use Set-StrictMode for your development scripts to identify code issues.

来自Get-Help Set-StrictMode -online：

The Set-StrictMode cmdlet configures strict mode for the current scope and all child scopes, and turns it on and off. When strict mode is on, PowerShell generates a terminating error when the content of an expression, script, or script block violates basic best-practice coding rules.

您可以立即使用 Set-StrictMode:

获得详尽的问题答案

Set-StrictMode -Version latest
$a=Get-Date  -format "yyyy-MM-dd"
$a.DayOfWeek -eq 'Tuesday'

The property 'DayOfWeek' cannot be found on this object. Verify that the property exists.
At line:3 char:1
+ $a.DayOfWeek -eq 'Tuesday'
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], PropertyNotFoundException
    + FullyQualifiedErrorId : PropertyNotFoundStrict

Answer 2

错误来自于您使用 -Format "yyyy-MM-dd"

将日期从 Get-Date 转换为 字符串

$a = Get-Date -format "yyyy-MM-dd"
$a.GetType()

表明 $a 现在是一个字符串。字符串不像 DateTime 对象那样有 DayOfWeek 属性。

只需删除 -Format 部分

$a = Get-Date

if($a.DayOfWeek -eq 'Tuesday') {
    Write-Host "Today is Tuesday"
}
else {
    Write-Host "Today is NOT Tuesday"
}
