PS B:\abrabackups> . C:\ps\ConvertTo-JSON.ps1
PS B:\abrabackups> Get-ItemProperty -Path .\AbraSuite01.03.2014 | select Name,CreationTime | ConvertTo-JSON
And that gives me: (formatted for clarity)
{
"CreationTime": "2014-01-03T16:48:36",
"Name": "AbraSuite01.03.2014"
}
Well that's all well and good, but suppose I want my dates in a different format in the JSON string, is there anyway to do this in powershell and still use my shoehorned ConvertTo-JSON.ps1 for powershell 2.0?
回答1:
Convert your dates to the format you want before converting to JSON by using a calculated property. For example:
Get-ItemProperty -Path .\AbraSuite01.03.2014 | select Name,@{Name="CreationTime";Expression={$_.CreationTime.ToShortDateString()}} | ConvertTo-JSON
Replace $_.CreationTime.ToShortDateString() with whatever you need to get the date format you're after - but the key here is to use $_.CreationTime to grab the creation time of the object in the pipeline.
