Question

我试图在我的C＃Web应用程序中通过PasswordRecovery控件生成的电子邮件中包含一个附加变量。我有一个User_Profile表，其中包含用户的名字和姓氏，但我不知道如何通过变量使用将该信息传递给HTML电子邮件模板。 <%Username%>和<%Password%>工作正常，但在尝试传递firstName时，我得到的只是占位符。这就是我所拥有的：

ASPX：

<asp:HiddenField ID="hfFirstName" runat="server" />
<asp:PasswordRecovery ID="ResetPassword" runat="server" ClientIDMode="Static" OnSendingMail="ResetPassword_SendingMail">
<MailDefinition BodyFileName="~/EmailTemplates/HTMLEmailPWReset.html" IsBodyHtml="true" Subject="Your password has been reset" />
  <UserNameTemplate>
    <h2>Reset my password</h2>
    <p>Forgot your password? Enter your User Name below.</p>
    <div class="form-group">
      <asp:TextBox ID="UserName" CssClass="form-control" placeholder="User Name" runat="server" />
      <asp:RequiredFieldValidator ID="UserNameRequired" runat="server" ControlToValidate="UserName" CssClass="field-validation-error" ErrorMessage="User Name is required" ValidationGroup="ResetPassword" Display="Dynamic" />
      <asp:Label ID="FailureText" runat="server" CssClass="field-validation-error" EnableViewState="False" />
    </div>

    <div class="row">
      <div class="col-md-6">
        <asp:Button ID="SubmitButton" runat="server" CommandName="Submit" Text="Submit" CssClass="btn btn-primary btn-block" ValidationGroup="ResetPassword" />
      </div>
      <div class="col-md-6">
        <asp:Button ID="cancel" CssClass="btn btn-default btn-block" runat="server" Text="Cancel" OnClick="cancel_Click" CausesValidation="false" />
      </div>
    </div>
  </UserNameTemplate>

  <QuestionTemplate>
    <h2>Reset my password</h2>
    <h4>Identity Confirmation</h4>
    <p>Please answer the following security question to receive your new password.</p>
    <div class="form-group">
      <label><strong>User Name:</strong>
      </label>
      <asp:label ID="UserName" CssClass="form-control form-control-static" runat="server" />
    </div>

    <div class="form-group">
      <label><strong>Question:</strong>
      </label>
      <asp:label ID="Question" CssClass="form-control" runat="server" />
    </div>

    <div class="form-group">
      <label><strong>Answer:</strong>
      </label>
      <asp:textbox ID="Answer" runat="server" CssClass="form-control" />
      <asp:RequiredFieldValidator ID="AnswerRequired" ControlToValidate="Answer" ErrorMessage="Answer is required" runat="server" CssClass="field-validation-error" Display="Dynamic" />

    </div>

    <div class="form-group">
      <div class="row">
        <div class="col-md-6">
          <asp:Button ID="SubmitButton" runat="server" CommandName="Submit" Text="Submit" CssClass="btn btn-primary btn-block" ValidationGroup="ResetPassword" />
        </div>
        <div class="col-md-6">
          <asp:Button ID="cancel" CssClass="btn btn-default btn-block" runat="server" Text="Cancel" OnClick="cancel_Click" CausesValidation="false" />
        </div>
      </div>
    </div>

    <asp:Label ID="FailureText" runat="server" CssClass="field-validation-error" EnableViewState="False" />

  </QuestionTemplate>

  <SuccessTemplate>
    <h2>Reset my password</h2>
    <div class="form-group">
      <p>Your new password has been sent to your registration email address.</p>
      <p>
        <asp:Button ID="continue" CssClass="btn btn-primary btn-block" runat="server" Text="Continue" OnClick="cancel_Click" CausesValidation="false" />
      </p>
    </div>
  </SuccessTemplate>
</asp:PasswordRecovery>

HTML电子邮件模板：

<body class="auto-style2">
<p>Hi <%FirstName%>.</p>
<p>According to our records... Your new password is: <strong><%Password%></strong></p>
<p>Thank you.</p>
</body>

C＃：

protected void ResetPassword_SendingMail(object sender, MailMessageEventArgs e)
{
    GetUserProfile();
    string firstName = hfFirstName.Value;
    e.Message.Body.Replace("<%FirstName%>", firstName);
}

private void GetUserProfile()
{
    string userName = (Convert.ToString(((TextBox)ResetPassword.Controls[0].FindControl("UserName")).Text));

    using (SqlConnection con = new SqlConnection(sqlConString))
    {
        try
        {
            SqlCommand cmd = new SqlCommand(
            @"SELECT * 
            FROM [dbo].[User_Profile] UP
            INNER JOIN [Users] U
            ON U.[UserId] = UP.[UserId]
            WHERE U.[UserName] = @userName");
            cmd.Connection = con;
            cmd.CommandType = CommandType.Text;
            cmd.Parameters.Add(new SqlParameter("@userName", userName));
            con.Open();

            SqlDataReader PopulateReader;
            PopulateReader = cmd.ExecuteReader();

            while (PopulateReader.Read())
            {
                hfFirstName.Value = (PopulateReader["FirstName"].ToString());
            }
        }
        catch (Exception ex)
        {
            log.InfoFormat("Exception caught in GetUserProfile(): {0}", ex.ToString());
            log.Info(Environment.NewLine + "End Exception" + Environment.NewLine);
        }
    }
}

我意识到GetUserProfile（）/ HiddenField方法可能不是最好的，但它存储并检索＆＃39; firstName＆＃39;的正确值。变量。看起来故障发生在e.Message.Body.Replace("<%FirstName%>", firstName);，但我没有收到任何错误，我无法确定占位符没有被替换的原因。我在这里做错了什么想法？

提前感谢您的光临，任何帮助都会受到最高的评价。

在这里找到我的答案：String is not replaced in CreateUserWizard Registration Email。 e.Message.Body.Replace("<%FirstName%>", firstName);不正确。正确的方法是e.Message.Body = e.Message.Body.Replace("<%FirstName%>", firstName.ToString());。现在，占位符已正确替换为所需的值。感谢。

包括＆lt;％Username％＆gt;以外的变量和＆lt;％Password％＆gt;在PasswordRecovery电子邮件中
