write to file array by lines

[Suliman via Digitalmars-d]

I have got:
string [] total_content;

I am appending to it data on every iteration.

total_content ~= somedata

File file = File(`D:\code\2vlad\result.txt`, "a+");
file.write(total_content);

I need to write it's to file by lines. Like:
somedataline1
somedataline2
somedataline3

I tried to do like:
total_content ~= somedata ~ "\n"

but in result I am getting all data in one line:
somedataline1 "\n" somedataline2 "\n" somedataline3 "\n"

what I am doing wrong? I know about split, but how it can be 
called on writing time?
