Question

I’m trying to create a MailMessage, and I’m getting the following error…

Cannot implicitly convert type 'string' to 'bool'

This is my init statement:

MailMessage msg = new MailMessage("[e-mail]",
                      myTbl.Rows[i]["Requester"].ToString().Trim(),
                      subject, 
                      "Dear " + myTbl.Rows[i]["Ship_Attention"].ToString() + ",<br/><br/>" +
                      body + "<br/>Your ISO ID is " + myTbl.Rows[i]["ISO_ID"].ToString() + 
                      (Convert.ToInt32(myTbl.Rows[i]["EmailType"]) == 1) ? 
                          ("<br/>Tracking Number: " + myTbl.Rows[i]["Tracking_No"].ToString()) : 
                          ("") + "<br/><br/>Please examine the loaned items for this transaction:<br/><br/>" +
                      sw.ToString());

I’m trying to add to the string at runtime based on a boolean expression. Why can’t I do this? Am I not doing it right?

string + (true | false) ? "somestring" : "anotherstring" + string

Answer 1

the ? : operator has very low precedence. Put it in parenthesis and I think you’ll resolve your issue.

((true|false)?"somestring":"anotherstring")
