我有一个JSON文件,我需要使用类System.Web.Script.Serialization
反序列化。以下代码:
string json = File.ReadAllText(@"C:\file.json");
JavaScriptSerializer ser = new JavaScriptSerializer();
var dict = ser.Deserialize<Dictionary<string, object>>(json);
创建一个嵌套字典,如下所示:
Dictionary<string, Object> outerDictionary;
Dictionary<string, Object> middleDictionary;
Dictionary<string, string> innerDictionary;
我现在需要从innerDictionary中获取一些值到C#对象类中,如:
public class Location
{
public string Id { get; set; }
public string Name { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
}
所以我的问题是,如何迭代嵌套的disctionary以获得我最需要的值?

在Jonesopolis
的帮助下,我现在有了正确的循环结构,但是我仍然无法从最里面的字典中获取值?
foreach (var outer in dict)
{
foreach (var middle in (Dictionary<string, object>)outer.Value)
{
foreach (var inner in (ArrayList)middle.Value)
{
foreach (var loc in (Dictionary<string, object>)inner)
{
}
}
}
}

如果您不喜欢Jonesopolis's answer中的嵌套foreach
,那么您可以这样使用LINQ:
var data = from outer in dict
from middle in (Dictionary<string, object>) outer.Value
from inner in (Dictionary<string, string>) middle.Value
select new { outer, middle, inner };
foreach (var item in data) {
// do things with item.inner
}
答案 1 :(得分:0)
如果您真的想使用这些对象:
foreach(var outer in dict)
{
foreach (var middle in (Dictionary<string, object>) outer.Value)
{
foreach (var inner in (Dictionary<string, string>) middle.Value)
{
var location = new Location();
location.Id = inner["Id"];
//etc..
}
}
}
但是,创建一个可以反序列化json的类结构会更好,它可以准确地表示你的数据,而不是生成字典。
