How to put a new line inside a string in C# source code?

Question

Is there a way in C# sytax for defining a new line? (Like in VB _ )

Example:

Instead of:

string myStr = "very long string" +
"another long string";

This:

string myStr = "very long string \something
another long string"

Or; does compiler handles this and does something like; "string" + "string" -> "stringstring" in this example?

Different cases are welcome like when these strings are constants, etc.

Answer 1

You can use

string myStr = @"very long string
another long string";

@" is the beginning of a string literal and this kind of string does not end until the next " character is found.

There is not an exact syntax for c# which does the same thing as _ character in vb. So if you want to avoid including a new line, you must manually connect your strings on different lines.

Answer 2

Compiler turns "ABC" + "DEF" into "ABCDEF" so there's no cost in using +

Answer 3

A StringBuilder should be used wherever possible to concatenate strings as it runs faster than simply using "this" + "that".

Answer 4

I believe what you are looking for is the C# line continuation character.

Stop looking. There is none. In C# a line ends when a semicolon ";" is reached.

Thus, as others have mentioned, if you want to break up a string assignment, simply use the '+' character.

{
    class Program
    {
     public static void Main(string[] args)
     {
      string s = "Hello World! " +
       "This is a long string " +
       "That continues on and " +
       "on and on and on.";
      Console.WriteLine(s);
      Console.ReadKey(true);
     }
    }
}
