最常用的使用方式是json格式
.net递归实现对象生成json格式字符串
代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using Newtonsoft.Json; using SubSonic; using System.Data; using System.Text; namespace WebApplication1 { public partial class Test2 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { ss(); } } protected string JsonString { set; get; } /* [ {name:"test1", open:true, children:[ {name:"test1_1"}, {name:"test1_2"}]}, {name:"test2", open:true, children:[ {name:"test2_1"}, {name:"test2_2"}]} ]; * */ List<MyTree> list = new List<MyTree>(); public void ss() { string sql = " SELECT * FROM Test1.DBO.ceshi where Fidh='ROOT' "; DataTable dt1 = new DataTable(); QueryCommand qc = new InlineQuery("Test1").GetCommand(sql); dt1 = DataService.GetDataSet(qc).Tables[0]; for (int i = 0; i < dt1.Rows.Count; i++) { MyTree rootTree = new MyTree(); rootTree.name = dt1.Rows[i]["Name"].ToString(); aa(dt1.Rows[i]["Id"].ToString(),rootTree); list.Add(rootTree); } string s = JsonConvert.SerializeObject(list); JsonString = s; } public void aa(string id,MyTree rootTree) { string sql1 = " SELECT * FROM Test1.DBO.ceshi where Fidh='" + id + "' "; DataTable dt = new DataTable(); QueryCommand qc1 = new InlineQuery("Test1").GetCommand(sql1); dt = DataService.GetDataSet(qc1).Tables[0]; if (dt.Rows.Count > 0) { rootTree.children = new List<MyTree>(); for (int j = 0; j < dt.Rows.Count; j++) { MyTree childTree = new MyTree(); childTree.name = dt.Rows[j]["Name"].ToString(); aa(dt.Rows[j]["Id"].ToString(), childTree); rootTree.children.Add(childTree); } } } } public class MyTree { public string name { get; set; } public List<MyTree> children { get; set; } } }
