entityMap|blocks|key|f2t7l|text|我更喜欢使用foreach遍历PowerShell对象：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|63ba0|foreach($object_properties+in+$obj.PsObject.Properties)

I prefer using <code>foreach</code> to loop through PowerShell objects:

<pre><code>foreach($object_properties in $obj.PsObject.Properties)
{
 # Access the name of the property
 $object_properties.Name

 # Access the value of the property
 $object_properties.Value
}
</code></pre>

Generally, <code>foreach</code> has higher performance than <code>Foreach-Object</code>.

And yes, <code>foreach</code> is actually different than <code>Foreach-Object</code> under the hood.

entityMap|blocks|key|d8m77|text|对于Get-Member，您可能也需要NoteProperty。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|132jh|$documents+%7C+Get-Member+-membertype+property,noteproperty+%7C+

You might need NoteProperty too with Get-Member. 

<pre><code>$documents | Get-Member -membertype property,noteproperty | 
 Foreach name
</code></pre>

EDIT: type "properties" seems a more generic catchall

<pre><code>$documents | get-member -type properties | % name
</code></pre>

EDIT: dump out all the values:

<pre><code>$obj = ls test.ps1
$obj | Get-Member -Type properties | foreach name | 
 foreach { $_ + ' = ' + $obj.$_ }

Attributes = Normal
CreationTime = 06/01/2019 11:29:03

LastAccessTimeUtc = 06/06/2019 03:19:01
LastWriteTime = 06/01/2019 11:29:03
LastWriteTimeUtc = 06/01/2019 15:29:03
Length = 55
Name = test.ps1
</code></pre>

An alternative way without "| foreach name", that needs extra parentheses:

<pre><code>$obj | Get-Member -Type properties | 
 foreach { $_.name + ' = ' + $obj.($_.name) }
</code></pre>

Another take which results in an array that's easier to work with, and might be good for objects converted from json:

<pre><code>$a = '{ prop1:1, prop2:2, prop3:3 }' | convertfrom-json 
$a

prop1 prop2 prop3
----- ----- -----
 1 2 3

$a.PSObject.Properties | select name,value

name value
---- -----
prop1 1
prop2 2
prop3 3
</code></pre>

I use the following command to enumerate the properties and put them in a table:

<pre><code>$Object.PSObject.Properties | Format-Table @{ Label = 'Type'; Expression = { "[$($($_.TypeNameOfValue).Split('.')[-1])]" } }, Name, Value -AutoSize -Wrap
</code></pre>

I wrote the following function around this, that iterates through nested properties as well.

<pre><code>function Enumerate-ObjectProperties {
 param (
 [psobject] $Object,
 [string] $Root
 )

 Write-Output $($Object.PSObject.Properties | Format-Table @{ Label = 'Type'; Expression = { "[$($($_.TypeNameOfValue).Split('.')[-1])]" } }, Name, Value -AutoSize -Wrap | Out-String)

 foreach ($Property in $Object.PSObject.Properties) {
 # Strings always have a single property "Length". Do not enumerate this.
 if (($Property.TypeNameOfValue -ne 'System.String') -and ($($Object.$($Property.Name).PSObject.Properties))) {
 $NewRoot = $($($Root + '.' + $($Property.Name)).Trim('.'))
 Write-Output "Property: $($NewRoot)"
 Enumerate-ObjectProperties -Object $($Object.$($Property.Name)) -Root $NewRoot
 }
 }
}

Enumerate-ObjectProperties $YourObject
</code></pre>

However please do keep in mind that some object are constructed somewhat typical, in the sense that they have 'loops' in their nesting. Subproperties that refer to parent objects.
An example being:

<pre><code>Get-Date 'somebogusdata'
Enumerate-ObjectProperties $Error[0]
</code></pre>

This will create a loop.
You could of course add a 'depth' parameter to add a depth counter, specifying you only want to go to a certain depth.
That would look something like this:

<pre><code>$script:Level = 1
function Enumerate-ObjectProperties {
    param (
        [psobject] $Object,
        [int32] $Depth = 1,
 [string] $Root
    )

    Write-Output $($Object.PSObject.Properties | Format-Table @{ Label = 'Type'; Expression = { "[$($($_.TypeNameOfValue).Split('.')[-1])]" } }, Name, Value -AutoSize -Wrap | Out-String)

    foreach ($Property in $Object.PSObject.Properties) {
        # Strings always have a single property "Length". Do not enumerate this.
        if (($Property.TypeNameOfValue -ne 'System.String') -and ($($Object.$($Property.Name).PSObject.Properties)) -and ($Level -le $Depth)) {
            $NewRoot = $($($Root + '.' + $($Property.Name)).Trim('.'))
            $Level++
 Write-Output "Property: $($NewRoot) (Level: $Level)"
            Enumerate-ObjectProperties -Object $($Object.$($Property.Name)) -Root $NewRoot
 $Level--
        }
    }
}

Enumerate-ObjectProperties -Object $Error[0] -Depth 2
</code></pre>

I have this <code>PSObject</code> (from XML):

<pre><code>bool : {IsActive, ShowOnB2C, ShowOnB2B, IsWebNews}
str : {id, ProductId, GroupName, Unit...}
int : {ProductIdNumeric, Prices_SalesOne, Prices_Treater, Prices_B2C...}
arr : {EnvironmentBrands, Catalogs, NavisionLevels}
long : long
</code></pre>

I would like to iterate over the properties without using the property names, for instance <code>bool</code>.

I have tried to index into the object like this:

<pre><code>$document[0]
</code></pre>

But that gives me nothing, but it does not cause any errors either.

<code>Select-Object</code> kind of works, but then I have to use the property names, and I don't want that.

<pre><code>$documents | Select-Object bool,str
</code></pre>

<code>ForEach</code> do not iterate the properties.

<pre><code>$documents | ForEach {
 $_.name
}
</code></pre>

returns doc and that is the name of the tag (XML) holding the bools, ints, and strings.
