Question

StringBuilder sb = new StringBuilder();
sb.Append("Line 1");
//insert new line character
//insert tab character
sb.Append("Line 2");
using (StreamWriter sw = new StreamWriter("example.txt"))
{
    sq.Write(sb.ToString());
}

How can insert a new line and tab character in this example?

Answer 1

StringBuilder sb = new StringBuilder();
sb.Append("Line 1");
sb.Append(System.Environment.NewLine); //Change line
sb.Append("\t"); //Add tabulation
sb.Append("Line 2");
using (StreamWriter sw = new StreamWriter("example.txt"))
{
    sw.Write(sb.ToString());
}

You can find detailed documentation on TAB (and other escape character here).
