我正在尝试以有效的方式使用C#以有效的JSON格式编写行 该文件应该是什么样的:
[
{
"uuid": "c92161ba-7571-3313-9b59-5c615d25251c",
"name": "thijmen321"
},
{
"uuid": "3b90891d-e6fc-44cc-a1a8-e822378ec148",
"name": "TehGTypo"
},
{
"uuid": "5f820c39-5883-4392-b174-3125ac05e38c",
"name": "CaptainSparklez"
}
]
我已经拥有了名称和UUID,但我需要一种方法将它们写入文件。我想一个接一个地做这个,所以,首先文件看起来像这样:
[
{
"uuid": "c92161ba-7571-3313-9b59-5c615d25251c",
"name": "thijmen321"
}
]
然后像这样:
[
{
"uuid": "c92161ba-7571-3313-9b59-5c615d25251c",
"name": "thijmen321"
},
{
"uuid": "3b90891d-e6fc-44cc-a1a8-e822378ec148",
"name": "TehGTypo"
}
]
等。但是,当然,UUID和名称是不同的,所以如何在不使用任何API等的情况下以有效的方式实现这一点? 我当前(效率很低)的代码:
public void addToWhitelist()
{
if (String.IsNullOrEmpty(whitelistAddTextBox.Text)) return;
string player = String.Empty;
try
{
string url = String.Format("https://api.mojang.com/users/profiles/minecraft/{0}", whitelistAddTextBox.Text);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url));
request.Credentials = CredentialCache.DefaultCredentials;
using (WebResponse response = request.GetResponse())
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
player = reader.ReadToEnd();
}
catch (WebException ex)
{
Extensions.ShowError("Cannot connect to http://api.mojang.com/! Check if you have a valid internet connection. Stacktrace: " + ex, MessageBoxIcon.Error);
}
catch (Exception ex)
{
Extensions.ShowError("An error occured! Stacktrace: " + ex, MessageBoxIcon.Error);
}
if (String.IsNullOrWhiteSpace(player)) { Extensions.ShowError("This player doesn't seem to exist.", MessageBoxIcon.Error); return; }
player = player.Replace(",\"legacy\":true", "")
.Replace("\"id", " \"uuid")
.Replace("\"name", " \"name")
.Replace(",", ",\n")
.Replace("{", " {\n")
.Replace("}", "\n },");
File.WriteAllText(Program.programPath + @"\Servers\" + servers[currentIndex].Name + @"\whitelist.json", "");
try
{
using (StreamWriter sw = File.AppendText(Program.programPath + @"\Servers\" + servers[currentIndex].Name + @"\whitelist.json"))
{
sw.WriteLine("[");
foreach (string s in File.ReadAllLines(Program.programPath + @"\Servers\" + servers[currentIndex].Name + @"\whitelist.json"))
if (s.Contains("[") || s.Contains("]") || s.Equals(Environment.NewLine)) continue;
else sw.WriteLine(s);
sw.WriteLine(player);
sw.WriteLine("]");
whitelistListBox.Items.Add("\n" + whitelistAddTextBox.Text);
}
}
catch (Exception ex) { Extensions.ShowError("An error occured while update whitelist.json! Stacktrace: " + ex); }
whitelistAddTextBox.Clear();
}

尝试json.net它将为您执行序列化工作:http://www.newtonsoft.com/json
答案 1 :(得分:1)
推荐的“微软”方式是与数据合同和DataContractJsonSerializer ..见这里
联系的一个例子是:
[DataContract]
internal class Person
{
[DataMember]
internal string name;
[DataMember]
internal string Uuid ;
}
您以下列方式使用该类(显然)
Person p = new Person();
p.name = "John";
p.Uuid = "3b90891d-e6fc-44cc-a1a8-e822378ec148";
并使用Contract Serializer序列化
MemoryStream stream1 = new MemoryStream();
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Person));
ser.WriteObject(stream1, p);
显示序列化数据的示例:
stream1.Position = 0;
StreamReader sr = new StreamReader(stream1);
Console.WriteLine(sr.ReadToEnd());

我会使用像http://www.newtonsoft.com/json
这样的JSON序列化程序这将允许您将uuid / name作为一个类滚动,而不是自己进行解析
类似于:
internal class UuidNamePair
{
string Uuid { get; set; }
string Name { get; set; }
}
然后在调用它时,你会做这样的事情:
List<UuidNamePair> lst = new List<UuidNamePair>();
lst.Add(new UuidNamePair() { Name = "thijmen321", Uuid = "c92161ba-7571-3313-9b59-5c615d25251c" });
lst.Add(new UuidNamePair() { Name = "TehGTypo", Uuid = "3b90891d-e6fc-44cc-a1a8-e822378ec148" });
string json = JsonConvert.SerializeObject(lst, Formatting.Indented);
Console.WriteLine(json);
您可以将POST发送到Web服务,或者尝试使用此json,而不是Console.WriteLine。
