您可以使用以下标准方法来获取格式化的 Json
JsonReaderWriterFactory.CreateJsonWriter(Stream stream, Encoding encoding, bool ownsStream, bool indent, string indentChars)
只设置 "indent==true"
试试这样的
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 序列化程序,您应该使用 InvariantCulture 以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 的格式无效有时会导致它们。
用于反序列化
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!
