推荐答案

您可以使用 JavaScriptSerializer 类来转换C＃类 / object 到 JSON 格式，就像这里演示的那样：从ASP.NET中的Web服务返回JSON响应



或者，您可以使用Newtonsoft的 SerializeObject ：在.NET中创建Web服务以返回XML和JSON数据



要将 DataTable 转换为 JSON ，请参阅以下讨论：转换DataT能够JSON

You can use the JavaScriptSerializer class to transform a C# class/object into JSON format just like what is demonstrated here: Return JSON Response From Web Service In ASP.NET

Alternatively, you could use Newtonsoft's SerializeObject: Creating Web Services In .NET To Return XML And JSON Data

To transform DataTable to JSON, see this discussion: Convert DataTable to JSON
