Solution 1

Since this is ASP.NET, try replacing Environment.NewLine with "<br />"

You are right, but how do you know where in HTML is is inserted? It could be inserted in a textarea, then it will need a type separator. Next time keep it in mind. :-) I voted 5 for now.

Please see my general answer. OP needs to know how to insert correctly, first of all.

Solution 5

You insert incorrectly. The only reasonable way is:

C#

string format = "My first line;{0}My second line";

//...

string separatedForTextBox = string.Format(format, System.Environment.NewLine);
string separatedForHtml = string.Format(format, "<br />");

Please keep in mind: string is immutable, so "+" is not efficient. (Do I have to explain why?)

There is no technical problem here it's the logic which is not giving proper result.

when you said incorrect you should have explained what is happening in his case. see my answer.

The only reasonable way... if you are talking about performance, yes please explain "why". And when you give any theory please stick to current question's scenario only.

It may be safe to say string.Format is good to use and has 100s of feature but does it fit in current scenario? I always believe performance improvement solution depends on the scenario so if solution A can improve performance in Scenario 1 it doesn't gurantee it will improve performance in Scenario 2

thanks,

I will explain why when OP asks me. For experts it must be obvious.

"And when you give any theory please stick to current question's scenario only." - No. Why should I?

"I always believe performance improvement solution depends on the scenario". You absolutely right, but in case of format it always beats "+" or at least provides the same speed. As it's also more readable, it's better.

The problem is you are adding new line at the end of the message so
if your message is

Message = "abcd #signature#";

the first code line Message = Message + Environment.NewLine; will result in

Message = "abcd #signature# + NewLine character"

and the second line

MIDL

Message = Message.Replace("#Signature#",
 obju.Signature);

will replace the signature before new line character hence end result will be:

Message = "abcd TheSignature + NewLine character"

Solution:
Modify above code like this:

MIDL

//Message = Message + Environment.NewLine;
                 Message = Message.Replace("#Signature#",
 Environment.NewLine + obju.Signature);

Hope it will help.

Thanks,

Solution 4

You need to use the break instead of the NewLine:

MIDL

Message = Message + "";
 Message = Message.Replace("#Signature#",
 obju.Signature);

No this is not right answer not even close. See my answer for the problem what is happening in OP's case. He implemented the same logic in his javascript code i.e. adding new line character before signature.
