need to replace hyperlinks in email body template html-CodePudding

I have an email body template for sending email to a customer with shipping tracking nos and links to the tracking site.

The logic enables me to use this template for including upto 5 tracking nos and links. If in case a customer has only 2 tracking nos, the logic should delete other three fields.

html template for email body:

<body>
        Dear [FIRSTNAME]{LAST NAME},
    Your package was shipped via USPS using tracking # [TRACKINGNUMBER1], [TRACKINGNUMBER2], [TRACKINGNUMBER3], [TRACKINGNUMBER4], [TRACKINGNUMBER5]
    Track your package(s) : <a href="https://xUSPSx//[TRACKINGNUMBER1]">Click Here (#1)</a>,
    <a href="https://xUSPSx//[TRACKINGNUMBER2]">Click Here (#2)</a>,
    <a href="https://xUSPSx//[TRACKINGNUMBER3]">Click Here (#3)</a>,
    <a href="https://xUSPSx//[TRACKINGNUMBER4]">Click Here (#4)</a>,
    <a href="https://xUSPSx//[TRACKINGNUMBER5]">Click Here (#5)</a>
    Thank You.
</body>

Controller logic:

If(orderinfo.shipmethod=="FedEx")
{
emailtemplate=emailtemplate.replace("Your package was shipped via USPS","Your package was shipped via FedEx");
emailtemplate=emailtemplate.replace("https://xUSPSx//","https://xFEDEXx//");
}
string trackingnos[]=// receives all tracking nos
int arraylength=trackingnos.length;
for(int i=0; i<arraylength;i  )
{
emailtemplate=emailtemplate.replace("[TRACKINGNUMBER"   (i 1)   "], trackingnos[i]);
}
for(;arraylength<=5; arraylength  )
{
emailtemplate=emailtemplate.replace(", [TRACKINGNUMBER"   (i 1)   "], "");
emailtemplate=emailtemplate.replace(", Click Here (#"   arraylength   ")", "" );
}

the following controller logic works for replacing the tracking nos but the hyperlinks are still not replaced for blank fields. Could you pls suggest a correction in my logic

CodePudding user response：

Why do you use a template if you are going to replace everything? Why not construct it from scratch?

This is how I do it in my program adjusted to your case.

 private void SendEmail() //parameters if needed Client client, OrderInfo orderinfo
    {
        string trackingnos[] = ;// receives all tracking nos
        int arraylength = trackingnos.length;
        StringBuilder emailtemplate = new StringBuilder();
        emailtemplate.Append("<body>     Dear "   client.FIRSTNAME   " "   client.LastNAME   ", <br/>");
        emailtemplate.Append("Your package was shipped via "   orderinfo.shipmethod   "using tracking # ");
        for (int i = 0; i < arraylength; i  )
        {
            if (i != arraylength - 1)
            {
                emailtemplate.Append(trackingnos[i]   ", ");
            }
            else
            {
                emailtemplate.Append(trackingnos[i]   ", <br/>");
            }
        }
        emailtemplate.Append("Track your package(s) : <br/>");
        for (int i = 0; i < arraylength; i  )
        {
            emailtemplate.Append("<a href=\"https://x" orderinfo.shipmethod "x//"   trackingnos[i]  "\">Click Here (#" i ")</a>  <br/>");
        }
        emailtemplate.Append("Thank you. <br/> </body> ");

        Microsoft.Office.Interop.Outlook.MailItem eMail = OutlookApplication.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
        eMail.Subject = "Package shipped";
        eMail.To = client.Email;
        eMail.HTMLBody = emailtemplate.ToString();
        eMail.Send();
    }
