JSON.Net deserialize string which contains special

问题:

How do I parse JSON string with one of the values containing special characters?

JObject obj = JObject.Parse(str);

str value:

{
  "message": "some !@#$%^&*(){}:"?/?/|"':>;><{"d":"v"}"
}

I have got execption: After parsing a value an unexpected character was encountered: {.

Take your JSON and .stringify() it.

{
  "message": JSON.stringify("your text here")
}

If you have raw data in your ASP.NET MVC view, you can follow this way:

{
  "message": JSON.stringify("@Html.Raw(HttpUtility.JavaScriptStringEncode(Model.MyString))")
}

You can also try more preferred way:

JSON.stringify({ "message" : message });

That JSON is invalid. If a JSON string contains special characters like double quotes ", backslashes \ or slashes /, they need to be escaped with backslashes \. (See JSON.org.) No JSON parser, including Json.Net, will be able to deal with a JSON string that isn't properly formatted in the first place.

Your JSON would need to look like this to be able to be parsed correctly:

{
  "message": "some !@#$%^&*(){}:\"?/?/|\"':>;><{\"d\":\"v\"}"
}

The solution is to correctly serialize the string at the source.
