Java：写入OutputStream，然后将其用作InputStream(Java: Write to OutputStream and then use it as InputStream)

 您的数据格式可能是JSON，但您只提供了一部分。 我稍微修改了一下： 
 
{"0":
    {
        "key":"valueWithAnyCharInside",
        "key2":"valueWithAnyCharInside",
        "key3":"valueWithAnyCharInside" 
    }
}
 
 现在你可以解析如下： 
 
string json = ...; //your json goes here

var serializer = new JavaScriptSerializer();
var parsed =  serializer.Deserialize<Dictionary<string, Dictionary<string, string>>>(json);

//printing data
parsed["0"].Select(pair => string.Format( "{0} - {1}", pair.Key, pair.Value))
           .ToList()
           .ForEach(Console.WriteLine);
 
 打印： 
 
key - valueWithAnyCharInside
key2 - valueWithAnyCharInside
key3 - valueWithAnyCharInside
 
 
 要获得强类型List<Item>使用下一个代码 
 
List<Item> items = parsed.Select(pair => new Item { Id = int.Parse(pair.Key),
                                                    Data = pair.Value})
                         .ToList();
 
 项目是： 
 
class Item
{
    public int Id { get; set; }
    public Dictionary<string, string> Data {get;set;}
}

Your data format is probably a JSON, but you gave only a part of it. I've modified it slightly as:
 
{"0":
    {
        "key":"valueWithAnyCharInside",
        "key2":"valueWithAnyCharInside",
        "key3":"valueWithAnyCharInside" 
    }
}
 
now you can parse it as following:
 
string json = ...; //your json goes here

var serializer = new JavaScriptSerializer();
var parsed =  serializer.Deserialize<Dictionary<string, Dictionary<string, string>>>(json);

//printing data
parsed["0"].Select(pair => string.Format( "{0} - {1}", pair.Key, pair.Value))
           .ToList()
           .ForEach(Console.WriteLine);
 
prints:
 
key - valueWithAnyCharInside
key2 - valueWithAnyCharInside
key3 - valueWithAnyCharInside
 
 
To get strongly typed List<Item> use next code
 
List<Item> items = parsed.Select(pair => new Item { Id = int.Parse(pair.Key),
                                                    Data = pair.Value})
                         .ToList();
 
Where Item is :
 
class Item
{
    public int Id { get; set; }
    public Dictionary<string, string> Data {get;set;}
}
