asp.net DataSet转换成josn并输出

public class JsonUtil
    {
        public string ToJson(DataSet dataSet)
        {
            string jsonString = "{";
            foreach (DataTable table in dataSet.Tables)
            {
                jsonString += """" + table.TableName + """:" + ToJson(table) + ",";
            }
            jsonString = jsonString.TrimEnd(',');
            return jsonString + "}";
        }
        public string ToJson(DataTable dt)
        {
            StringBuilder jsonString = new StringBuilder();
            jsonString.Append("[");
            DataRowCollection drc = dt.Rows;
            for (int i = 0; i 

使用

 JsonUtil ju = new JsonUtil();
 Response.Write(ju.ToJson(ds)); 

如果解析有问题可以把代码中的""""用"\""替换
