在字符串中插入换行符 [英] Insert newline in string

问题描述

大家好，
我正在尝试构造要发送给用户的消息.
在添加签名之前，我要插入换行符.
我正在使用以下代码.

hi all,
i m trying to contruct messages to be sent to users.
befroe adding the signature i want to insert a newline.
i m using the below code.

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

但邮件发送时没有换行符.

谁能帮忙吗?

but the messages are sent without a newline.

can anyone please help?
thanks.

推荐答案

由于这是ASP.NET，请尝试将Environment.NewLine替换为< br/>"

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

您插入不正确.唯一合理的方法是:

You insert incorrectly. The only reasonable way is:

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

//...

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

请记住:字符串是不可变的，因此"+"效率不高. (我必须解释为什么吗?)

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

问题是您在消息末尾添加了新行，因此
如果您的留言是

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

Message = "abcd #signature#";

第一行代码Message = Message + Environment.NewLine;将导致

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

Message = "abcd #signature# + NewLine character"

第二行

and the second line

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

将在换行符之前替换签名，因此最终结果将是:

消息="abcd TheSignature +换行符"

解决方案:
像这样修改上面的代码:

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

Message = "abcd TheSignature + NewLine character"

Solution:
Modify above code like this:

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

希望对您有所帮助.
