new line in a multi-line string

Question

Trying to override a tostring in one of my classes.

 return string.Format(@" name = {0}
                         ID = {1}
                         sec nr = {2}
                         acc nr = {3}", string, int, int ,int); // types

But the thing is, the result isn't aligned when printed out:

name = test
                                   ID = 42
                                   sec nr = 11
                                   acc nr = 55

Trying to add \n just prints it out without formating. Guessing it has something to do with @"" which I'm using for multi-lining.

Would like it to print out :

name = test
ID = 42
sec nr = 11
acc nr = 55

Answer 1

The @ before the string switches off standard C# string formatting, try

 return string.Format(" name = {0}\n ID = {1} \n sec nr = {2} \n acc nr = {3}", 
                      string, int, int ,int); // types

You can't use the @ and use \n, \t etc.

EDIT

This is - IMHO - as good as it gets

 return string.Format("name = {0}\n" + 
                      "ID = {1}\n" + 
                      "sec nr = {2}\n" + 
                      "acc nr = {3}", 
                       string, int, int ,int); 

Answer 2

If you add spaces in front, it will be printed that way.

I normally do it like this.

   return string.Format(
@" name = {0}
 ID = {1}
 sec nr = {2}
 acc nr = {3}", string, int, int ,int); // types

Update: Perhaps a prettier alternative:

string[] lines = 
{
  " name = {0}",
  " ID = {1}",
  " sec nr = {2}",
  " acc nr = {3}"
};

return string.Format(
         string.Join(Environment.Newline, lines), 
         arg0, arg1, arg2, arg3);
