本文介绍了使用LINQ在嵌套JSON/JTOKEN中获取价值的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我是LINQ
查询的新手,并且想知道是否可以通过LINQ
查询实现我要实现的目标.
I am new to LINQ
queries and would like to know if what I am trying to achieve is possible via LINQ
query.
因此,我有一个JSON文档,如下所示.
So, I have a JSON doc as below.
我正在尝试获取与"$ type" 匹配的所有值,并向我返回目录路径和$ type的值.
I am trying to get all the values that match the "$type" and return me the directory path and the value for $type.
我知道执行此操作的交互式方式,但是LINQ似乎是首选,并且应该很容易实现.
I know an interactive way of doing this but it seems LINQ is preferred and supposed to be easy to get this.
{
"$type":"type1",
"title":"US version",
"_object1":[
{
"$type":"type2",
"rootModule":{
"id":"page",
"modules":[
{
"id":"header",
"$type":"module-header"
},
{
"id":"footer",
"$type":"module-footer"
}
]
}
},
{
"$type":"type2",
"_id":"ab134"
},
{
"$type":"type3",
"_id":"ab567"
}
],
"_object2":[
{
"$type":"module1",
"constraintsId":"page"
},
{
"name":"header1 1",
"nestedobject":{
"$type":"nestedobject-type",
"dataBinder":{
"id":"ab244"
}
}
}
]
}
推荐答案
谢谢大家
我能够得到如下列表:
var root = (JContainer)JToken.FromObject(document, CommonSerializerSetting.GetCommonSerializer());
var descendant = "$type";
var query = root
// Recursively descend the JSON hierarchy
.DescendantsAndSelf()
// Select all properties named descendant
.OfType<JProperty>()
.Where(p => p.Name == descendant)
// Select their value
.Select(p => p.Value);
