基本上我到处都搜索过，而且我找不到任何适用于我情况的东西。
我正在使用Overwatch（一款游戏）的API，我想从网上下载一个String，并检查它是否有一个JSON字符串。
让我告诉你代码：
< !--language: c# -->
HttpClient dc = new HttpClient();
string tag = e.Message.Text.ToString().Substring(7).Replace("#", "-");
string apiurl = (@"http://api.lootbox.eu/" + "pc/" + "global/" + tag + "/profile");
HttpResponseMessage datares = await dc.GetAsync(apiurl);
string finaldata = await datares.Content.ReadAsStringAsync();
#region PC
if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "pc/" + "us/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "pc/" + "kr/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "pc/" + "eu/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "pc/" + "cn/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
#endregion
#region XBOX LIVE
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "xbl/" + "us/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "xbl/" + "eu/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "xbl/" + "kr/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "xbl/" + "cn/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "xbl/" + "global/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
#endregion
#region PSN
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "psn/" + "us/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "psn/" + "global/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "psn/" + "cn/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "psn/" + "eu/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
else if (finaldata.Contains(":404"))
{
apiurl = (@"http://api.lootbox.eu/" + "psn/" + "kr/" + tag + "/profile");
datares = await dc.GetAsync(apiurl);
finaldata = await datares.Content.ReadAsStringAsync();
}
#endregion
DataTable obj = JsonConvert.DeserializeObject(finaldata);
因此，在这种情况下，示例输出将是：
{"data":{"username":"Rezoh","level":305,"games":{"quick":{"wins":"378"},"competitive":{"wins":"82","lost":85,"played":"167"}},"playtime":{"quick":"88 hours","competitive":"36 hours"},"avatar":"https://blzgdapipro-a.akamaihd.net/game/unlocks/0x0250000000000D70.png","competitive":{"rank":"3392","rank_img":"https://blzgdapipro-a.akamaihd.net/game/rank-icons/season-2/rank-5.png"},"levelFrame":"https://blzgdapipro-a.akamaihd.net/game/playerlevelrewards/0x025000000000092D_Border.png","star":"https://blzgdapipro-a.akamaihd.net/game/playerlevelrewards/0x025000000000092D_Rank.png"}}
现在我需要将其转换为某种类型的表格。
我得到了JSON.Net，但是大多数人说要在转换之前设置一个类，
问题是：我有2＆＃34;胜利＆＃34;：和3＆＃34;竞争＆＃34;：正如您在JSON字符串中看到的那样。
因此，在这种情况下，我的信念是不可能的。我尝试制作一个新的DataTable，如最后一行代码所示，但在使用"Cannot implicitly convert type object to System.Data.DataTable"时它告诉我JsonConvert.DeserializeObject(finaldata);我甚至尝试过.ToString();和dates变量，同样.ToString()。
我需要一种正确的方式来显示这些统计数据，例如，我可以显示：
"Stats for user " + obj.Name + ":"
"Wins: " + obj.Wins
"Losses: " + obj.Losses
"Rank: " + obj.Rank
在我的情况下，没有在线解决方案可以帮助我。
编辑：
这个解决方案对我来说都不起作用：
convert json String to datatable? 或这个 Nested Json String to DataTable
这也不是：
var token = JToken.Parse(finaldata);
if (token.Type == JTokenType.Object)
token = new JArray(token);
var a = token.ToObject<DataTable>();
答案 0 :(得分：1)
你可以按照他们的说法使用课程。我使用http://json2csharp.com/但VS也可以这样做。
您可以在此处试用：https://dotnetfiddle.net/iaIvOn
using System;
using Newtonsoft.Json;
public class Program
{
public void Main()
{
var json = @"{""data"":{""username"":""Rezoh"",""level"":305,""games"":{""quick"":{""wins"":""378""},""competitive"":{""wins"":""82"",""lost"":85,""played"":""167""}},""playtime"":{""quick"":""88 hours"",""competitive"":""36 hours""},""avatar"":""https://blzgdapipro-a.akamaihd.net/game/unlocks/0x0250000000000D70.png"",""competitive"":{""rank"":""3392"",""rank_img"":""https://blzgdapipro-a.akamaihd.net/game/rank-icons/season-2/rank-5.png""},""levelFrame"":""https://blzgdapipro-a.akamaihd.net/game/playerlevelrewards/0x025000000000092D_Border.png"",""star"":""https://blzgdapipro-a.akamaihd.net/game/playerlevelrewards/0x025000000000092D_Rank.png""}}";
// read the doc: http://www.newtonsoft.com/json
var rootObject = JsonConvert.DeserializeObject<RootObject>(json);
Console.WriteLine("Stats for user " + rootObject.Data.Username + ":");
Console.WriteLine("Wins: " + rootObject.Data.Games.Competitive.Wins);
Console.WriteLine("Losses: " + rootObject.Data.Games.Competitive.Lost);
Console.WriteLine("Rank: " + rootObject.Data.Competitive.Rank);
}
public class Quick
{
// Free case support!
public string Wins { get; set; }
}
public class Competitive
{
public string Wins { get; set; } // you may want to check this string here ;)
public int Lost { get; set; }
public string Played { get; set; }
}
public class Games
{
public Quick Quick { get; set; }
public Competitive Competitive { get; set; }
}
public class Playtime
{
public string Quick { get; set; }
public string Competitive { get; set; }
}
public class Competitive2
{
public string Rank { get; set; }
// attribute ftw! http://www.newtonsoft.com/json/help/html/SerializationAttributes.htm
[JsonProperty(PropertyName = "rank_img")]
public string RankImg { get; set; }
}
public class Data
{
public string Username { get; set; }
public int Level { get; set; }
public Games Games { get; set; }
public Playtime Playtime { get; set; }
public string Avatar { get; set; }
public Competitive2 Competitive { get; set; }
public string LevelFrame { get; set; }
public string Star { get; set; }
}
public class RootObject
{
public Data Data { get; set; }
}
}
输出
Stats for user Rezoh:
Wins: 82
Losses: 85
Rank: 3392
如果Quick和Competitive是游戏，可能是：
public abstract class Game
{
public string Wins { get; set; } // you may want to check this string here ;)
public int Lost { get; set; }
public string Played { get; set; }
}
public class Quick : Game // note that Quick game has Lost and PLayed now!
{
}
public class Competitive : Game
{
}
甚至（正如@EpicSam在评论中提出的那样）：
public class Game
{
public string Wins { get; set; } // you may want to check this string here ;)
public int Lost { get; set; }
public string Played { get; set; }
}
public class Games
{
public Game Quick { get; set; }
public Game Competitive { get; set; }
}
