.Net实现微信公共服务平台开发中的发送文本消息功能，具体内容如下

首先建立一个微信消息类。

class wxmessage { public string FromUserName { get; set; } public string ToUserName { get; set; } public string MsgType { get; set; } public string EventName { get; set; } public string Content { get; set; } public string EventKey { get; set; } }

后台代码如下：

protected void Page_Load(object sender, EventArgs e) { wxmessage wx = GetWxMessage(); string res = ""; if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe") {//刚关注时的时间，用于欢迎词 string content = ""; content = "/:rose欢迎北京永杰友信科技有限公司/:rose\n直接回复“你好”"; res = sendTextMessage(wx, content); } else { if (wx.MsgType == "text" && wx.Content == "你好") { res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!"); } else { res = sendTextMessage(wx, "你好,未能识别消息!"); } } Response.Write(res); } private wxmessage GetWxMessage() { wxmessage wx = new wxmessage(); StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8); XmlDocument xml = new XmlDocument(); xml.Load(str); wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText; wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText; wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText; if (wx.MsgType.Trim() == "text") { wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText; } if (wx.MsgType.Trim() == "event") { wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText; } return wx; }/// /// 发送文字消息 /// /// 获取的收发者信息 /// 内容 /// private string sendTextMessage(wxmessage wx, string content) { string res = string.Format(@" ", wx.FromUserName, wx.ToUserName, DateTime.Now, content); return res; }
