PowerShell - 如何判断两个对象是否相同 [英] PowerShell - How to tell if two objects are identical

问题描述

假设您有两个相同的对象(意味着它们分别具有相同的属性和相同的值).

Let's say you have two objects that are identical (meaning they have the same properties and the same values respectively).

你如何测试相等性?

示例

$obj1 &$obj2 相同

这是我尝试过的:

if($obj1 -eq $obj2)
{
    echo 'true'
} else {
    echo 'false'
}
# RETURNS "false"

if(Compare-Object -ReferenceObject $obj1 -DifferenceObject $obj2)
{
    echo 'true'
} else {
    echo 'false'
}
# RETURNS "false"

编辑

这不相同

推荐答案

你可以通过Compare-Object比较两个PSObject对象的属性和值是否相等PSObject 对象的 Properties 属性.示例:

You can compare two PSObject objects for equality of properties and values by using Compare-Object to compare the Properties properties of both PSObjectobjects. Example:

if ( -not (Compare-Object $obj1.PSObject.Properties $obj2.PSObject.Properties) ) {
  "object properties and values match"
}
else {
  "object properties and values do not match"
}

如果你想在函数中使用它:

If you want it in a function:

function Test-PSCustomObjectEquality {
  param(
    [Parameter(Mandatory = $true)]
    [PSCustomObject] $firstObject,

    [Parameter(Mandatory = $true)]
    [PSCustomObject] $secondObject
  )
  -not (Compare-Object $firstObject.PSObject.Properties $secondObject.PSObject.Properties)
}
