我们都知道在AjaxPro的方法AjaxPro.Utility.RegisterTypeForAjax(typeof(所在类的类名));会将标记有[Ajax.AjaxMethod]方法注册在客户端。在某项目中，设计模板字段引擎，采用html+jquery实现，这里的数据就难免需要ajax获取，但是团队对于js掌握不一，所以我写了下面辅助类，可以像ajaxpro一样简化ajax的开发。
代码-jQueryInvokeMethodAttribute （此处只做标示方法处理，所以为空）：
[AttributeUsage(AttributeTargets.Method, AllowMultiple=false,Inherited=false)] public class jQueryInvokeMethodAttribute : Attribute { }代码-jQueryAjaxUtility（分注册脚本和调用ajax事件）：View Code
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Green.Utility { public class jQueryAjaxUtility { public static string AjaxInvokeParam = "AjaxInvoke"; public static string AjaxInvokeValue = "1"; public static string ResponseCharset = "UTF-8"; protected static System.Web.UI.Page Page { get { return System.Web.HttpContext.Current.Handler as System.Web.UI.Page; } } public static void RegisterClientAjaxScript(Type type) { if (Page != null) { if (System.Web.HttpContext.Current.Request[AjaxInvokeParam] == AjaxInvokeValue) { RegisterAjaxInvokeEvent(type); } else { RegisterAjaxInvokeScript(type); } } } protected static void RegisterAjaxInvokeScript(Type type) { Page.ClientScript.RegisterClientScriptBlock(type.GetType(), type.GetType().FullName + "_" + typeof(jQueryAjaxUtility).FullName + "_AjaxInvokeDefaultOption", "window.defaultAjaxOption={type:'GET',cache:false, dataType:'text'};", true); if (!jQueryUtilityCache.Current.Exists(type)) { var methodinfo = type.GetMethods(System.Reflection.BindingFlags.IgnoreCase | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public).Where(t => { var attrs = t.GetCustomAttributes(typeof(jQueryInvokeMethodAttribute), false); if (attrs != null && attrs.Length > 0) return true; return false; }).ToList(); if (methodinfo != null && methodinfo.Count > 0) { System.Text.StringBuilder sb = new StringBuilder(); sb.AppendFormat(" window.{0}=function(){{}}; ", type.Name); methodinfo.ForEach(t => { var parameters = t.GetParameters().Select(p => p.Name).ToArray(); sb.AppendFormat(" {2}.{0} = function ({1} ajaxOption) {{", t.Name, parameters.Count() > 0 ? string.Join(",", parameters) + "," : "", type.Name); sb.Append("if(ajaxOption==null||typeof ajaxOption=='undefined'){ajaxOption={};};"); var url = Page.Request.RawUrl.IndexOf("?") == -1 ? Page.Request.RawUrl : Page.Request.RawUrl.Substring(0, Page.Request.RawUrl.IndexOf("?") ); sb.AppendFormat("ajaxOption.url = '{0}';", url); var data = "''"; if (parameters.Count() > 0) { data = (string.Join(" ", parameters.Select(p => string.Format("'&{0}=' + {0}+", p)).ToArray())); data= data.TrimEnd('+'); } sb.AppendFormat("ajaxOption.data = 'method={1}&rn={4}&{2}={3}'+{0};", data, t.Name, AjaxInvokeParam, AjaxInvokeValue,Guid.NewGuid().ToString()); sb.Append("ajaxOption= jQuery.extend(window.defaultAjaxOption,ajaxOption);"); sb.Append("jQuery.ajax(ajaxOption);};"); }); jQueryUtilityCache.Current.AddScript(type, sb.ToString()); } } var script = jQueryUtilityCache.Current.GetScript(type); Page.ClientScript.RegisterClientScriptBlock(type.GetType(), type.GetType().FullName + "_" + typeof(jQueryAjaxUtility).FullName + "_AjaxInvoke", script, true); } protected string GenertorScript(Type type) { return string.Empty; } protected static void RegisterAjaxInvokeEvent(Type type) { var Request = System.Web.HttpContext.Current.Request; var Response = System.Web.HttpContext.Current.Response; var method = Request["method"]; if (string.IsNullOrEmpty(method)) return; Response.Clear(); var methodinfo = type.GetMethod(method, System.Reflection.BindingFlags.IgnoreCase | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public); if (methodinfo != null) { Response.Charset = ResponseCharset; Response.ContentType = string.Join(",", Request.AcceptTypes); var param = methodinfo.GetParameters(); object[] objs = new object[param.Length]; var i = 0; param.ToList().ForEach(t => { objs[i++] = Convert.ChangeType(Request[t.Name], t.ParameterType); }); var obj = methodinfo.Invoke(null, objs); if (obj != null) { //序列化 if (!obj.GetType().IsValueType && obj.GetType() != typeof(string)) { if (Request.AcceptTypes.Contains("text/xml")) { Response.Write(Green.Utility.SerializerUtility.XmlSerializer(obj)); } else if (Request.AcceptTypes.Contains("application/json")) { Response.ContentType = "application/json, text/javascript, */*"; Response.Write(Green.Utility.SerializerUtility.JsonSerializer(obj)); } else { Response.Write(obj); } } else { Response.Write(obj); } } Response.Flush(); Response.Close(); Response.End(); } } } } 复制代码为了考虑反射的性能，加入了类级注册脚本方法缓存处理jQueryUtilityCache，具体见demo。
测试：
html: <form id="form1" runat="server"> <div> <input id="Button1" type="button" value="button" /> </div> </form>

_Default.Test("ajax", { success: function(e) { alert(e); }, dataType: "text" });后台：
