By default, any object created from JSON uses String as a data type:
$json = @" { "Name": "Weltner", "ID" : "123" } "@ $info = ConvertFrom-Json -InputObject $json $info.Name $info.ID
JSON does support data types, though, although JSON data types are not identical to .NET data types. Note in the following code how "ID" is declared as "number", and how a number is assigned that no longer needs quoting.
$json = @" { "Name": "Weltner", number: "ID" : 123 } "@ $info = ConvertFrom-Json -InputObject $json $info.Name $info.ID
However, when using ConvertFrom-Json, it turns out that PowerShell is not honoring the data type declaration. It always turns values into String data.
