ASP.NET AJAX反序列化

Question

For some reason, in ASP.NET AJAX, when I do this:

Sys.Serialization.JavaScriptSerializer.serialize({attachToValidators:true});

This is the result:

"{"attachToValidators":true}"

I try reversing the result:

Sys.Serialization.JavaScriptSerializer.deserialize("{\"attachToValidators\":true}");

or:

Sys.Serialization.JavaScriptSerializer.deserialize("{attachToValidators:true}");

I get this result:

Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON. Parameter name: data

Why is that?

Thanks.

答案发布在这里，尽管在3.5版本中对我来说效果很好，我不需要JSON.parse，所以我不知道发生了什么： http : //forums.asp.net/t/1631638.aspx

Answer 2

What are you trying to deserialize it to ? This is how JavaScriptSerializer works, for deserialization:

public class ValidatorInfo
{
  public bool attachToValidators { get; set; }
}

public void yourFunction()
{
  var js = new JavaScriptSerializer();

  ValidatorInfo info = js.Deserialize<ValidatorInfo>("{\"attachToValidators\":true}");

  // True.
  info.attachToValidators == true;
}

In your question, you're serializing an anonymous type, so you get away with not having an underlying type to serialize. That doesn't work on the way back in though.

If you need more dynamic behavior, Json.Net provides something like that with its LINQ implementation.
