这是我的代码：
列表< string> namesList = new List< string>（）;
dynamic json1 = JsonConvert.DeserializeObject（data）;
现在我卡住了...
我有两个问题：我必须阅读对象中的每个名字都像
realms / lang / de_DE.lang
问题是，我不知道名称和Internet上我只是发现如何读取动态json对象中的值，而不是如何读取名称它... ...
第二个问题是，在另一个类中，我必须处理所有这些数据，我也需要哈希值。计算每个文件的时刻（有675个文件）或将哈希值作为返回值计算散列值是否方便？
我已经返回一个列表转换为一个URL数组，所以我不知道如何返回URL和HASH，然后处理它们。
我使用foreach循环向名称列表中添加值：
namesList.Add（finalurl）;
然后我返回这个：
return namesList.ToArray（）;
解决方案
您应该像下面这样为反序列化创建类： p>
public class MyClass
{
[JsonProperty（objects）]
public IDictionary< string ，ObjectValue> Objects {get;组; }
$ b $ public class ObjectValue
{
[JsonProperty（hash）]
public string Hash {get;组; }
[JsonProperty（size）]
public long Size {get;组; }
}
然后你可以像这样得到你的名字：
MyClass json = JsonConvert.DeserializeObject< MyClass>（data）;
var names = json.Objects.Keys.ToList（）;
var hash = json.Objects [names [0]]。 //获取第一项的散列值
另外不要忘记检查 null 和其他可能的错误（没有数据等）。

Here is my code:
List<string> namesList = new List<string>();
dynamic json1 = JsonConvert.DeserializeObject(data);
Now I'm stuck... I have two problems: I have to read every name inside objects like
realms/lang/de_DE.lang
The problem is that i don't know the names and on the internet i just found how to read the values inside dynamic json objects and not how to read the name of it...
The second problem is that on another class i have to process all this data and i need the hashes too. Is it convenient to calculate the hash on the moment for every file(there are 675 files) or to pass the hashes as a return? I already return a list converted to an array of URL's so i don't know how to return both the URL's and the HASH and then process them. I add to the namelist the value with a foreach loop:
namesList.Add(finalurl);
And then i return this:
return namesList.ToArray();
解决方案
You should create classes for deserialization like this:
public class MyClass
{
[JsonProperty("objects")]
public IDictionary<string, ObjectValue> Objects { get; set; }
}
public class ObjectValue
{
[JsonProperty("hash")]
public string Hash { get; set; }
[JsonProperty("size")]
public long Size { get; set; }
}
and then you can get your names like this:
MyClass json = JsonConvert.DeserializeObject<MyClass>(data);
var names = json.Objects.Keys.ToList();
var hash = json.Objects[names[0]].Hash; // Get the hash of the first item
Also don't forget to check if null and other possible errors (no data etc).
