我正在使用. net JSON解析器，并想序列化我的配置文件，使其可读。所以不要:
{"blah":"v", "blah2":"v2"}
我想要更好的东西，比如:
{
"blah":"v",
"blah2":"v2"
}
我的代码是这样的:
using System.Web.Script.Serialization;
var ser = new JavaScriptSerializer();
configSz = ser.Serialize(config);
using (var f = (TextWriter)File.CreateText(configFn))
{
f.WriteLine(configSz);
f.Close();
}
当前回答
using System.Text.Json;
...
var parsedJson = JsonSerializer.Deserialize<ExpandoObject>(json);
var options = new JsonSerializerOptions() { WriteIndented = true };
return JsonSerializer.Serialize(parsedJson, options);
其他回答
onlineer使用Newtonsoft.Json.Linq:
string prettyJson = JToken.Parse(uglyJsonString).ToString(Formatting.Indented);
Net Core App
var js = JsonSerializer.Serialize(obj, new JsonSerializerOptions {
WriteIndented = true
});
using System.Text.Json;
...
var parsedJson = JsonSerializer.Deserialize<ExpandoObject>(json);
var options = new JsonSerializerOptions() { WriteIndented = true };
return JsonSerializer.Serialize(parsedJson, options);
你可以使用以下标准方法来获取格式化的Json
JsonReaderWriterFactory。CreateJsonWriter(流流，编码编码，bool ownsStream, bool缩进，字符串indentChars)
只设置"缩进==true"
试试这样的方法
public readonly DataContractJsonSerializerSettings Settings =
new DataContractJsonSerializerSettings
{ UseSimpleDictionaryFormat = true };
public void Keep<TValue>(TValue item, string path)
{
try
{
using (var stream = File.Open(path, FileMode.Create))
{
//var currentCulture = Thread.CurrentThread.CurrentCulture;
//Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
try
{
using (var writer = JsonReaderWriterFactory.CreateJsonWriter(
stream, Encoding.UTF8, true, true, " "))
{
var serializer = new DataContractJsonSerializer(type, Settings);
serializer.WriteObject(writer, item);
writer.Flush();
}
}
catch (Exception exception)
{
Debug.WriteLine(exception.ToString());
}
finally
{
//Thread.CurrentThread.CurrentCulture = currentCulture;
}
}
}
catch (Exception exception)
{
Debug.WriteLine(exception.ToString());
}
}
注意线条
var currentCulture = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
....
Thread.CurrentThread.CurrentCulture = currentCulture;
对于某些类型的xml序列化器，您应该使用InvariantCulture来避免在具有不同区域设置的计算机上反序列化期间出现异常。例如，double或DateTime的无效格式有时会导致错误。
在反序列化
public TValue Revive<TValue>(string path, params object[] constructorArgs)
{
try
{
using (var stream = File.OpenRead(path))
{
//var currentCulture = Thread.CurrentThread.CurrentCulture;
//Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
try
{
var serializer = new DataContractJsonSerializer(type, Settings);
var item = (TValue) serializer.ReadObject(stream);
if (Equals(item, null)) throw new Exception();
return item;
}
catch (Exception exception)
{
Debug.WriteLine(exception.ToString());
return (TValue) Activator.CreateInstance(type, constructorArgs);
}
finally
{
//Thread.CurrentThread.CurrentCulture = currentCulture;
}
}
}
catch
{
return (TValue) Activator.CreateInstance(typeof (TValue), constructorArgs);
}
}
谢谢!
使用System.Text.Json设置JsonSerializerOptions。writeindent = true:
JsonSerializerOptions options = new JsonSerializerOptions { WriteIndented = true };
string json = JsonSerializer.Serialize<Type>(object, options);
