TemplateMessage static class encapsulates methods related to template messages, see the table below:

Method name	Function
SetIndustry	Set industry
GetId	Get template id
Send	Send template message

2 Settings Industry

The SetIndustry method of the TemplateMessage class is used to set the industry to which the official account belongs. The method is defined as follows:

        /// <summary>
        /// 设置行业        /// </summary>
        /// <param name="userName">公众号</param>
        /// <param name="code1">行业代码1</param>
        /// <param name="code2">行业代码2</param>
        /// <returns>返回设置是否成功</returns>
        public static ErrorMessage SetIndustry(string userName, string code1, string code2)        //或者

        /// <summary>
        /// 设置行业        /// </summary>
        /// <param name="userName">公众号</param>
        /// <param name="industry1">行业1</param>
        /// <param name="industry2">行业2</param>
        /// <returns>返回设置是否成功</returns>
        public static ErrorMessage SetIndustry(string userName, Industry industry1, Industry industry2)

Among them, Industry is the industry class, and the static members in the class include all known industries. For example: Industry.OnlineGame represents the online game industry; the Industry class has three attributes, namely : Code——Industry code, Name——Industry name, PrimaryIndustry——Main industry.

Example of setting the industry:

/// <summary>
    /// 设置所属行业
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void btnSetIndustry_Click(object sender, EventArgs e)
    {
        string userName = lbPublicAccount.SelectedValue;
        string industryCode1 = "", industryCode2 = "";
        int count = 0;
        foreach (ListItem item in cblIndustry.Items)
        {
            if (item.Selected)
            {
                count++;
                if (count == 1)
                    industryCode1 = item.Value;
                else if (count == 2)
                {
                    industryCode2 = item.Value;
                    break;
                }
            }
        }
        if (count != 2)
            ltrMessage.Text = "请选择两个行业。";
        else
        {
            ErrorMessage errorMessage = TemplateMessage.SetIndustry(userName, industryCode1, industryCode2);
            ltrMessage.Text = string.Format("设置所属行业{0}。{1}",
                errorMessage.IsSuccess ? "成功" : "失败",
                errorMessage.IsSuccess ? "" : errorMessage.ToString());
        }
    }

##3 Get template id

The GetId method of the TemplateMessage class is used to obtain the template id. The method is defined as follows:

        /// <summary>
        /// 获取模板ID        /// </summary>
        /// <param name="userName">公众号</param>
        /// <param name="shortTemplateId">模板库中模板的编号，有“TM**”和“OPENTMTM**”等形式</param>
        /// <param name="errorMessage">返回获取是否成功</param>
        /// <returns>返回模板ID；如果获取失败，返回空字符串。</returns>
        public static string GetId(string userName, string shortTemplateId, out ErrorMessage errorMessage)

Note: (1) If the template has not been added yet, this method will first Add a template, and then return the template id; (2) If a template has been added, calling this method again will return a new template id different from the last obtained template id.

Example of getting template id:

    /// <summary>
    /// 添加并模板id    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void btnGetTemplateId_Click(object sender, EventArgs e)
    {        string userName = lbPublicAccount.SelectedValue;
        ErrorMessage errorMessage;        string templateId = TemplateMessage.GetId(userName, txtTemplateIdShort.Text, out errorMessage);        if (errorMessage.IsSuccess)
            ltrMessage.Text = string.Format("添加并获取模板id成功。模板id：{0}", templateId);        else
            ltrMessage.Text = string.Format("添加并获取模板id失败。{0}", errorMessage.ToString());
    }

        public long MsgID { get; private set; }
        /// <summary>

        public string Status { get; private set; }

        /// <summary>
        /// 获取消息是否群发成功

        public TemplateMessageSendStatusEnum SendStatus
        {
            get
            {
                TemplateMessageSendStatusEnum status;
                if (Status == sendFailedUserBlock)
                    status = TemplateMessageSendStatusEnum.UserBlock;
                else if (Status == sendFailedSystemFailed)
                    status = TemplateMessageSendStatusEnum.SystemFailed;
