基于Jquery ajax 与 Jquery插件 Ztree使用说明

public static string ObjectToJson<T>(string jsonName, IList<T> IL)
    {
        StringBuilder Json = new StringBuilder();
        Json.Append("[");
        if (IL.Count > 0)
        {
            for (int i = 0; i < IL.Count; i++)
            {
                T obj = Activator.CreateInstance<T>();
                Type type = obj.GetType();
                PropertyInfo[] pis = type.GetProperties();
                Json.Append("{");
                for (int j = 0; j < pis.Length; j++)
                {
                    Json.Append(""" + pis[j].Name.ToString() + "":"" + pis[j].GetValue(IL[i], null) + """);
                    if (j < pis.Length - 1)
                    {
                        Json.Append(",");
                    }
                }
                Json.Append("}");
                if (i < IL.Count - 1)
                {
                    Json.Append(",");
                }
            }
        }
        Json.Append("]");
        return Json.ToString();
    }

$(document).ready(function() {
        $.ajax({
            type: "POST",
            url: "programList.aspx/getClassData",
            dataType: "json",
            contentType: "application/json; charset=utf-8",
            success: function(msg) {
                alert(eval("(" + msg + ")").d);
            },
            error: function(xhr, msg, e) { alert(msg); }
        });
        // 初始化数据(显示第一页)
        onloadGrid(0);
        InitData(0, 0);
    });
