Question

我有2个我想合并的对象，但似乎找不到解决方案

我试过了 :

 function Join-Object {
    Param(
       [Parameter(Position=0)]
       $First
    ,
       [Parameter(Position=1,ValueFromPipeline=$true)]
       $Second
    )
    BEGIN {
       [string[]] $p1 = $First | gm -type Properties | select -expand Name
    }
    Process {
       $Output = $First | Select $p1
       foreach($p in $Second | gm -type Properties | Where { $p1 -notcontains $_.Name } | select -expand Name) {
          Add-Member -in $Output -type NoteProperty -name $p -value $Second."$p"
       }
       $Output
    }
 } # End: Function Join-Object

$TestCases = Join-Object $TxtTestcases $RexTestcases | Select Name, TestPlan, TestCase, Script, TestData, Error, ErrorCount, ErrorText, Messages, DateTime, Elapsed

但是第二个对象不存在:

Name         TestPlan     TestCase     Script       TestData            Error ErrorCount   ErrorText    Messages    DateTime   
----         --------     --------     ------       --------            ----- ----------   ---------    --------    --------   
test 1                                                                   True                           {\\APPS-...            
test 2                                                                  False                           {[APPS-E...            

我也尝试过:

Function Merge-Testcase {
Param ($TxtTestcase, $RexTestcase)
    $Fields = @{            
        Name        = $TxtTestcase.Name
        TestPlan    = $RexTestcase.TestPlan
        TestCase    = $RexTestcase.TestCase
        Script      = $RexTestcase.Script
        TestData    = $RexTestcase.TestData
        IsError     = $TxtTestcase.Error
        ErrourCount = $RexTestcase.ErrorCount
        ErrorText   = $RexTestcase.ErrorText
        Messages    = $TxtTestcase.Messages
        DateTime    = $RexTestcase.DateTime
        Elapsed     = $RexTestcase.Elapsed
    }
    New-Object PSObject -Property $Fields | ConvertTo-Csv -NoTypeInformation
} # End: Function Merge-Testcase
$TestCases = Merge-Testcase -TxtTestcase $TxtTestcases -RexTestcas $RexTestcase
$TestCases | Format-Table

但我得到这个

"Script","Name","TestCase","TestPlan","ErrorText","TestData","ErrourCount","IsError","Elapsed","DateTime","Messages"
,,,,,,,,,,

关于如何加入2个对象的任何想法吗？

Answer 1

选项1

一种选择是将两个对象都放入HashTable中，然后将其转换为PSCustomObject。

 $Obj1 = (Get-Process)[0]; # Get a process
 $Obj2 = (Get-Service)[0]; # Get a service
 ($Result = [PSCustomObject]@{ Obj1 = $Obj1; Obj2 = $Obj2; });

 $Result.Obj1.Name;
 $Result.Obj2.Name;

注意:这将创建您必须钻取的附加“级别”，因此虽然不理想，但可以使用。

选项＃2

第二个选项是遍历“第二个对象”的所有属性，并使用Add-Member将它们添加到“第一个对象”中，您的示例已经显示了。

创建一个名为c:\test\test.txt的空文件，然后运行以下代码:

# Get a couple of objects (with different property names)
$Object1 = Get-Service -Name Dnscache;
$Object2 = Get-Item c:\test\test.txt;

# Get a list of the properties on both objects
$PropertyList1 = @(Get-Member -InputObject $Object1 -MemberType Properties).Name;
$PropertyList2 = Get-Member -InputObject $Object2 -MemberType Properties | Where-Object -FilterScript { $PropertyList1 -notcontains $PSItem.Name; };

# Add the properties, from the second object, to the first object
foreach ($Property in $PropertyList2) {
    Write-Host ('Adding property: {0}' -f $Property.Name);
    Add-Member -InputObject $Object1 -Name $Property.Name -MemberType NoteProperty -Value $Object2.$($Property.Name);
}

# Output the object
$Object1 | select *;

输出如下所示:

看看服务和文件的属性如何都在一个对象上？
