C# escape characters

e.g.

for (int i = 0; i < speaker.Length; i++) {
    s.WriteLine(speakerAmt[i] + \t + speakerID[i]);
}

I'm trying to get a tab character in-between speakerAmt[i] and speakerID[i]. Do escape characters need to be in " " " " (quotation marks)?

EDIT: Thank you! in less than 50 seconds, I had about 5 answers. I'm impressed!

since C#6, it is even better to do:

for (var i = 0; i < speaker.Length; i++)
{
    s.WriteLine($"{speakerAmt[i]}\t{speakerID[i]}");
}

It is Interpolated Strings

Do this : 

for (int i = 0; i < speaker.Length; i++)
{
    s.WriteLine(speakerAmt[i] + "\t" + speakerID[i]);
}

And It's better to do following

for (int i = 0; i < speaker.Length; i++)
{
    s.WriteLine(string.Format("{0}\t{1}",speakerAmt[i],speakerID[i]);
}

Yup!

for (int i = 0; i < speaker.Length; i++)
{
   s.WriteLine(speakerAmt[i] + "\t" + speakerID[i]);
}

Yes, the quotes are necessary.

s.WriteLine(speakerAmt[i] + "\t" + speakerID[i]);

Why it is necessary:

Because this is an escape sequence that is part of a string. \t is . Like:

var hi = "Hello\tWorld";

The compiler just interprets this in a special manner when used in the context of a string. The \ character in a string usually denotes the beginning of an escape sequence (exception: string literals). Here is another example that also uses a tab using a different way:

var hi = "Hello\u0009World";

You can read more about strings, literals, and escape sequences as part of the documentation.

escape characters are characters, therefore they needs to be in single quotes '\t'. Or you can construct a string with one escape character which makes it "\t" . Without any quotes \t is illegal.

Yes, they need to be in a string

for (int i = 0; i < speaker.Length; i++)
{
   s.WriteLine(speakerAmt[i] + "\t" + speakerID[i]);

Yes - you need to do this:

 s.WriteLine(speakerAmt[i] + "\t" + speakerID[i]);
