1.先新建一个类库，以方便以后移植到其他的项目上继续使用，如何新建类库就自己去百度了哈，这里就不描述了，若有不会的朋友请留言哈。标红了的都要注意下咯。

 

2.先看看WxTemplate这个类文件的代码

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace WxTemplateMsg{    public class WxTemplate    {        /// 
        /// 目标用户OpenId        /// 
        public string touser { get; set; }        /// 
        /// 模板ID        /// 
        public string template_id { get; set; }        /// 
        /// 模板消息顶部颜色（16进制），默认为#FF0000        /// 
        public string topcolor { get; set; }        /// 
        /// 模板跳转链接        /// 
        public string url { get; set; }        /// 
        /// 数据        /// 
        public object data { get; set; }        public WxTemplate()        {            topcolor = "#FF0000";        }    }    public class TemplateDataItem    {        /// 
        /// 项目值        /// 
        public string value { get; set; }        /// 
        /// 16进制颜色代码，如：#FF0000        /// 
        public string color { get; set; }        /// 
        ///         /// 
        /// value        /// color        public TemplateDataItem(string v, string c = "#173177")        {            value = v;            color = c;        }    }}

TemplateModel文件夹是放不同模板的类文件，我这里的是金额变动的微信模板消息

MemRechargeTemplate.cs文件代码如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace WxTemplateMsg.TemplateModel{    public class MemRechargeTemplate    {        /// 
        /// 标题        /// 
        public TemplateDataItem first { get; set; }        /// 
        /// 日期        /// 
        public TemplateDataItem date { get; set; }        /// 
        /// 变动金额        /// 
        public TemplateDataItem adCharge { get; set; }        /// 
        ///         /// 
        public TemplateDataItem type { get; set; }        /// 
        /// 卡内余额        /// 
        public TemplateDataItem cashBalance { get; set; }        /// 
        /// 备注        /// 
        public TemplateDataItem remark { get; set; }    }}

3.怎么调用呢，看下面代码：

#region 发送模板消息                                 WxTemplateMsg.WxTemplate wxTemp = new WxTemplateMsg.WxTemplate();                                wxTemp.touser = openid;                                wxTemp.template_id = template_id;                                wxTemp.topcolor = "#FF0000";                                wxTemp.url = "http://" + PubFunction.curParameter.strDoMain + "/mobile/member/bill.aspx";                                MemRechargeTemplate memRecTemp = new MemRechargeTemplate();                                memRecTemp.first = new WxTemplateMsg.TemplateDataItem(title);                                memRecTemp.date = new WxTemplateMsg.TemplateDataItem(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss"));                                memRecTemp.adCharge = new WxTemplateMsg.TemplateDataItem((dclTotalRechargeMoney).ToString("#0.00"));                                memRecTemp.type = new WxTemplateMsg.TemplateDataItem("");                                memRecTemp.cashBalance = new WxTemplateMsg.TemplateDataItem(modelMem.MemMoney.ToString("#0.00"));                                memRecTemp.remark = new WxTemplateMsg.TemplateDataItem("点击“详情“立即查阅您的帐户财务记录。");                                wxTemp.data = memRecTemp;                                string res = PubFunction.PushTempleModel(wxTemp, access_token);                                if (!res.Contains("ok"))                                {                                    //PubFunction.LogError("会员充值推送错误》" + res);//这里是把错误日志进入到数据库的表中，这个就自行补脑了哈                                }                                #endregion

上面的代码中有一个方法：PushTempleModel

/// 
    /// 发送模板消息    /// 
    /// 
         public static string PushTempleModel(WxTemplateMsg.WxTemplate tm, string access_token)    {        string url = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=" + access_token;        HttpRequestHelper httpRequest = new HttpRequestHelper();        string postData = JavaScriptConvert.SerializeObject(tm);                string response = httpRequest.Reqeust(url, postData);//调用HTTP通信接口提交数据          return response;    }

 

HttpRequestHelper.cs文件的代码：

public string Reqeust(string url, string postText)        {            System.Net.HttpWebRequest request;            request = (System.Net.HttpWebRequest)WebRequest.Create(url);            //Post请求方式            request.Method = "POST";            // 内容类型            request.ContentType = "application/x-www-form-urlencoded";            //// 参数经过URL编码            //string paraUrlCoded = System.Web.HttpUtility.UrlEncode(postText);            byte[] payload;            //将URL编码后的字符串转化为字节            payload = System.Text.Encoding.UTF8.GetBytes(postText);            //设置请求的 ContentLength             request.ContentLength = payload.Length;            //获得请 求流            System.IO.Stream writer = request.GetRequestStream();            //将请求参数写入流            writer.Write(payload, 0, payload.Length);            // 关闭请求流            writer.Close();            System.Net.HttpWebResponse response;            // 获得响应流            response = (System.Net.HttpWebResponse)request.GetResponse();            System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8);            string responseText = reader.ReadToEnd();            reader.Close();            return responseText;        }
