如何将$ TwitterStatuses迭代为数组或对象? [英] how to iterate $TwitterStatuses as an array or as Objects?
问题描述
如何迭代每个$TwitterStatuses元素/项目/对象?
How can I iterate each $TwitterStatuses element/item/object?
(而且，如何检查每个状态"?)
(And, how do I inspect each "status"?)
Import-Module PSTwitterAPI
Set-TwitterOAuthSettings -ApiKey $env:ApiKey -ApiSecret $env:ApiSecret -AccessToken $env:AccessToken -AccessTokenSecret $env:AccessTokenSecret
#Get-TwitterUsers_Lookup -screen_name 'mkellerman'
$TwitterStatuses = Get-TwitterStatuses_UserTimeline -screen_name 'mkellerman'
#$TwitterStatuses = [array]Get-TwitterStatuses_UserTimeline -screen_name 'mkellerman'
Foreach ($status in $TwitterStatuses)
{
Write-Host $status
}
我正在阅读看起来像的某种投射"到数组的用法，但不确定与对象在这里.
I was reading what looked like a sort of "cast" to array usage, but not sure of the distinction from objects here.

推荐答案
您的查询已经很好.您不需要强制转换为数组.
从Get-TwitterStatuses_UserTimeline获得的结果已经是一个结果数组.
Your query is good already. You don't need to cast to array.
What you get from Get-TwitterStatuses_UserTimeline is already an array of results.
可以通过在对象上调用.GetType()方法来检查对象是哪种类型.
You can check which type is an object by calling the .GetType() method on them.
$TwitterStatuses.GetType()
(Get-Type方法可用于所有对象)
(The Get-Type method is available for all objects)
您可以使用Get-Member在要检查的对象上检查可用的成员.
You can inspect the members available using Get-Member on the object you want to inspect.
$TwitterStatuses | Get-Member
然后，在您的foreach中，您需要精确确定实际要显示的内容.
Then, in your foreach, you need to precise what you actually want to display.
示例
Foreach ($status in $TwitterStatuses)
{
Write-Host $status.text
}
如果只有一个属性感兴趣，您甚至可以通过访问属性名称直接获得结果. 集合将被迭代，结果将显示在控制台中.
If only one of the property interest you, you can even get the results directly by accessing the property name . The collection will be iterated and results displayed in the console.
$TwitterStatuses.text
