从JSON创建哈希表
问题描述：
我想获取Hashtable的JSON表示形式，例如:
I want to get a JSON representation of a Hashtable such as this:
@{Path="C:\temp"; Filter="*.js"}
ConvertTo-Json导致:
{
"Path": "C:\\temp",
"Filter": "*.js"
}
但是，如果使用ConvertFrom-Json将该JSON字符串转换回去，则不会得到HashTable，而是PSCustomObject.
However, if you convert that JSON string back with ConvertFrom-Json you don't get a HashTable but a PSCustomObject.
那么如何可靠地序列化上面的Hashmap?
So how can one reliably serialize the above Hashmap?
答
$json = @{Path="C:\temp"; Filter="*.js"} | ConvertTo-Json
$hashtable = @{}
(ConvertFrom-Json $json).psobject.properties | Foreach { $hashtable[$_.Name] = $_.Value }
