I’m using Json.net to deserialize json data received by Web API call. Some fields often have html-encoded characters like "
or &
How can I have this characters automatically decoded during deserialization?
I came to 2 possible solutions:
Calling System.Web.HttpUtility.HtmlDecode()
in property setter like:
public string Title
{
set
{
title = System.Web.HttpUtility.HtmlDecode(value);
}
}
Writing custom JsonConverter that calls System.Web.HttpUtility.HtmlDecode()
in ReadJson()
method:
public class HtmlEncodingConverter : Newtonsoft.Json.JsonConverter
{
public override bool CanConvert(Type objectType)
{
return objectType == typeof(String);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
return System.Web.HttpUtility.HtmlDecode((string)reader.Value);
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
writer.WriteRawValue(System.Web.HttpUtility.HtmlEncode((string)value));
}
}
But is there any built-in solution that allows to perform html-decoding during json deserialization without additional code?
System.Net.WebUtility.HtmlDecode()
or
HttpUtility.HtmlDecode()
is the way to go, nothing built in regarding the JsonSerializer.
