无法将值"Year"转换为类型 "System.Int32" 。错误："Input string was not in a correct format."

Question

code -

# Get current Year and Month
param ([Int]$Year, [Int]$Month, [String]$Environment, [String]$Report, [String]$Username, [String]$Password)
function Get-DaysOfMonth {
Param ([Int]$Year, [Int]$Month)
$MonthDays = New-Object System.Collections.Generic.List[System.Object]
1..([datetime]::DaysInMonth($Year, $Month)) |
ForEach-Object {
$Day = ([datetime]::ParseExact("$_/$Month/$Year", "d/M/yyyy", [System.Globalization.CultureInfo]::InvariantCulture)).ToString("dd")
$MonthDays.Add($Day)
}
return $MonthDays
}
Write-Host "The Year Selected is: " + [String]$Year
Write-Host "The Month Selected is: " + [String]$Month
Write-Host "The Environment Selected is: $Environment"
Write-Host "The Report Generated is: $Report"
Write-Host "Export Generating as User: $Username"
$Days = Get-DaysOfMonth -Year $Year -Month $Month

运行时，我得到以下回溯：

Cannot process argument 
transformation on parameter 'Year'. Cannot convert value "Year" to type 
"System.Int32". Error: "Input string was not in a correct format."
+ CategoryInfo          : InvalidData: (:) [myscript.ps1], ParentContai 
nsErrorRecordException
+ FullyQualifiedErrorId : ParameterArgumentTransformationError,myscript 
.ps1

似乎将我的整数变量转换为字符串时出现问题。 我该如何解决这个问题？

我正在通过以下命令运行脚本

myscript.ps1 -Year 2018 -Month 02 -Environment PROD -Report event -Username myacct -Password mypass

Write-Host命令仍然存在问题。

它在这里运行，但输出：

The Year Selected is:  + [String]2018
The Month Selected is:  + [String]2
The Environment Selected is: PROD
The Report Generated is: event
Export Generating as User: myacct

解决此问题的一种方法是使用字符串格式运算符：

"The Year Selected is: {0}`nThe Month Selected is: {1}`nThe Environment Selected is: {2}`nThe Report Generated is: {3}`nExport Generating as User: {4}" -f $Year,$Month,$Environment,$Report,$Username

---

The Year Selected is: 2018
The Month Selected is: 2
The Environment Selected is: PROD
The Report Generated is: event
Export Generating as User: myacct
