C#封装微信API的操作类源码下载

现在用微信公共平台的比较多，特封装一个微信的API类，方便调用。支持最新版4.5的5种推送消息类型和3种回复消息类型。对基本的请求验证和通过验证，接受消息和回复消息都有静态方法实现，不用再手工去做了。

using System;using System.Collections.Generic;using System.Xml;namespace WeiXinAPI{ public class NewsReplyMessage : Message { public List<Article> Articles; public NewsReplyMessage() { MsgType = MessageType.News; Direction = MessageDirection.Reply; FuncFlag = "1"; } public int ArticleCount { get { return Articles == null ? 0 : Articles.Count; } } public string FuncFlag { get; set; } public override bool Parse(string xmlMessageString) { //空消息 if (string.IsNullOrEmpty(xmlMessageString)) { return false; } //获取消息内容 try { var xmlDocument = new XmlDocument(); xmlDocument.LoadXml(xmlMessageString); XmlNode firstNode = xmlDocument.FirstChild; if (firstNode != null) { //消息类型 XmlNode tempNode = firstNode.SelectSingleNode("MsgType"); if (tempNode == null) return false; MsgType = tempNode.InnerText; //发送者 tempNode = firstNode.SelectSingleNode("FromUserName"); if (tempNode == null) return false; FromUserName = tempNode.InnerText; //接收者 tempNode = firstNode.SelectSingleNode("ToUserName"); if (tempNode == null) return false; ToUserName = tempNode.InnerText; //创建时间 tempNode = firstNode.SelectSingleNode("CreateTime"); if (tempNode == null) return false; CreateTime = Convert.ToInt64(tempNode.InnerText); //Articles tempNode = firstNode.SelectSingleNode("Articles"); if (tempNode != null) { if (tempNode.HasChildNodes) { Articles = new List<Article>(); foreach (XmlNode xmlNode in tempNode.ChildNodes) { XmlNode tmpNode = xmlNode.SelectSingleNode("Title"); if (tmpNode == null) return false; string title = tempNode.InnerText; tmpNode = xmlNode.SelectSingleNode("Discription"); if (tmpNode == null) return false; string description = tempNode.InnerText; tmpNode = xmlNode.SelectSingleNode("PicUrl"); if (tmpNode == null) return false; string picUrl = tempNode.InnerText; tmpNode = xmlNode.SelectSingleNode("Url"); if (tmpNode == null) return false; string url = tempNode.InnerText; Articles.Add(new Article(title, description, picUrl, url)); } } } //星标(FuncFlag=1时星标消息) tempNode = firstNode.SelectSingleNode("FuncFlag"); if (tempNode == null) return false; FuncFlag = tempNode.InnerText; return true; } return false; } catch { return false; } } public override string ToString() { string result = string.Format("<xml>" Environment.NewLine "<ToUserName><![CDATA[{0}]]></ToUserName>" Environment.NewLine "<FromUserName><![CDATA[{1}]]></FromUserName>" Environment.NewLine "<CreateTime>{2}</CreateTime>" Environment.NewLine "<MsgType><![CDATA[{3}]]></MsgType>" Environment.NewLine "<ArticleCount>{4}</ArticleCount>" Environment.NewLine, ToUserName, FromUserName, CreateTime, MsgType, ArticleCount); if (Articles.Count > 0) { result = "<Articles>" Environment.NewLine; foreach (Article article in Articles) { result = "<item>" Environment.NewLine "<Title><![CDATA[" article.Title "]]></Title>" Environment.NewLine "<Discription><![CDATA[" article.Description "]]></Discription>" Environment.NewLine "<PicUrl><![CDATA[" article.PicUrl "]]></PicUrl>" Environment.NewLine "<Url><![CDATA[" article.Url "]]></Url>" Environment.NewLine "</item>" Environment.NewLine; } result = "</Articles>" Environment.NewLine; } result = "<FuncFlag>" FuncFlag "</FuncFlag>" Environment.NewLine "</xml>"; return result; } }}
