Newline Inside a String To Be Shown At a TMemoBox
提问by Nathan Campos
I'm building a Stringcalled FullMemo, that would be displayed at a TMemoBox, but the problem is that I'm trying to make newlines like this:
我正在构建一个String被调用的FullMemo，它将显示在 a TMemoBox，但问题是我正在尝试像这样制作换行符：
FullMemo := txtFistMemo.Text + '\n' + txtDetails.Text
What I got is the content of txtFirstMemothe character \n, not a newline, and the content of txtDetails. What I should do to make the newline work?
我得到的是txtFirstMemo字符的内容\n，而不是换行符，以及txtDetails. 我应该怎么做才能使换行符工作？

The solution is to use #13#10 or better as Sertac suggested sLineBreak.
解决方案是使用 #13#10 或更好的 Sertac 建议sLineBreak。
FullMemo := txtFistMemo.Text + #13#10 + txtDetails.Text;
FullMemo := txtFistMemo.Text + sLineBreak + txtDetails.Text;

A more platform independent solution would be TStringList.
更独立于平台的解决方案是TStringList.
var
Strings: TStrings;
begin
Strings := TStringList.Create;
try
Strings.Assign(txtFirstMemo.Lines); // Assuming you use a TMemo
Strings.AddStrings(txtDetails.Lines);
FullMemo := Strings.Text;
finally
Strings.Free;
end;
end;
To Add an empty newline you can use:
要添加一个空的换行符，您可以使用：
Strings.Add('');

Use
用
FullMemo := txtFistMemo.Text + #13#10 + txtDetails.Text

You don't make newlines like this, you use symbol #13:
您不会像这样创建换行符，而是使用符号 #13：
FullMemo := txtFistMemo.Text + #13 + txtDetails.Text
+ Chr(13) + 'some more text'#13.
#13 is CR, #10 is LF, sometimes it's enough to use just CR, sometimes (when writing text files for instance) use #13#10.
#13 是 CR，#10 是 LF，有时只使用 CR 就足够了，有时（例如在编写文本文件时）使用 #13#10。

You can declare something like this:
你可以这样声明：
const
CRLF = #13#10;
LBRK = CRLF+ CRLF;
in a common unit and use it in all your programs. It will be really handy.
在一个公共单元中并在您的所有程序中使用它。真的会很方便。
