PowerShell-访问JObject内的JArray [英] PowerShell -- Accessing a JArray inside a JObject

问题描述

我有一个Json对象

 {
  "ProjectDirectory": "C:\\Main",
  "SiteName": "RemoteOrder",
  "ParentPath": "/Areas//Views",
  "VirtualDirectories": [
        {
          "Name": "Alerts",
          "Path": "\\Areas\\RemoteOrder\\Views\\Alerts"
        },
        {
          "Name": "Analytics",
          "Path": "\\Areas\\RemoteOrder\\Views\\Analytics"
        },
        {
          "Name": "Auth",
          "Path": "\\Areas\\RemoteOrder\\Views\\Auth"
        }
    ]
}

我创建的

$config = [Newtonsoft.Json.Linq.JObject]::Parse($file)

我可以访问

$config["ProjectDirectory"]
$config["VirtualDirectories"]

但是我无法到达VirtualDirectories JArray内部的元素

But I can not get to the element inside the VirtualDirectories JArray

我确认

 $config["VirtualDirectories"][0].GetType() // JObject
 $config["VirtualDirectories"].GetType() // JArray
 $config // JObject

我尝试过

$config["VirtualDirectories"][0]["Name"]
$config["VirtualDirectories"][0]["Path"]
$config["VirtualDirectories"][0][0]
$config["VirtualDirectories"][0].GetValue("Name")

当我尝试

 $config["VirtualDirectories"][0].ToString()

我知道

{
      "Name": "Alerts",
      "Path": "\\Areas\\RemoteOrder\\Views\\Alerts"
}

我真正想做的是访问它的一个循环，但是我似乎再也无法访问JObject Elements

What I am really trying to do is access it a loop but again I can not seem to access the JObject Elements

推荐答案

您很亲密. $config["VirtualDirectories"][0]["Name"]将为您提供一个包含文本的JValue.您只需要从此处使用Value属性即可获取实际的字符串.这是在ForEach循环中执行的操作:

You are close. $config["VirtualDirectories"][0]["Name"] will give you a JValue containing the text. You just need to use the Value property from there to get the actual string. Here is how you would do it in a ForEach loop:

$config = [Newtonsoft.Json.Linq.JObject]::Parse($file)

ForEach ($dir in $config["VirtualDirectories"])
{
    $name = $dir["Name"].Value
    $path = $dir["Path"].Value
    ...
}
