I'm trying to support a legacy app I made a year ago and need to use jQuery AJAX calls to get data from the server. I have a JsonHelper class that I use to serialize DataTables and DataSets. This normally works fine in .NET 4.0, but .NET 2.0 there is no System.Web.Script.Serialization library and therefore no JavaScriptSerializer class.
我正在尝试支持一年前制作的遗留应用程序,需要使用jQuery AJAX调用从服务器获取数据。我有一个JsonHelper类,用于序列化DataTables和DataSet。这通常在.NET 4.0中工作正常,但.NET 2.0没有System.Web.Script.Serialization库,因此没有JavaScriptSerializer类。
I've tried to find another JSON serializer, but so far I can't get anything to work.
我试图找到另一个JSON序列化程序,但到目前为止我无法得到任何工作。
I tried using JSON.NET 2.0 http://json.codeplex.com/releases/view/13099 but it said it needed a higher framework. So I tried JSON.NET 1.3.1 http://json.codeplex.com/releases/view/6987 I could only figure out how to write JSON to a .txt file, and I'd like to just be able to pass the string back to the client.

I also just tried JsonFx.NET http://jsonfx.net/download/ serialization library (for 2.0). Still couldn't get anything to work.
我也尝试过JsonFx.NET http://jsonfx.net/download/序列化库(适用于2.0)。仍然无法得到任何工作。
I don't know if I'm missing some crucial element of these libraries or if there is an easy solution.
我不知道我是否遗漏了这些库中的一些关键元素,或者是否有一个简单的解决方案。
Thanks in advance

The Jayrock Library works with all versions of .Net all the way down to 1.x. You'll have to build it yourself for 2.0, but that's no big deal.
Jayrock库可以与.Net的所有版本一起使用,直到1.x.你必须自己为2.0构建它,但这没什么大不了的。
I've used it for the past few months. Nice and simple Json serialization and deserialization.
过去几个月我一直用它。简单的Json序列化和反序列化。

Easy (but not elegant) solution is to create a shim in .NET 4 that will call your legacy application via HTTP POST or SOAP and convert result in JSON format with NewtonSoft.Json which works OK on .NET 4.
简单(但不是优雅)的解决方案是在.NET 4中创建一个垫片,它将通过HTTP POST或SOAP调用您的遗留应用程序,并使用NewtonSoft.Json将结果转换为JSON格式,这在.NET 4上运行正常。
