To add a whole new line to a StringBuilder we can use the AppendLine method:
using System;
using System.Text;
class Sample
{
public static void Main()
{
StringBuilder sb = new StringBuilder();
string[] strs = new string[] { "a", "v", "c" };
foreach (string s in strs)
{
sb.AppendLine(s);
}
Console.WriteLine(sb);
}
}
The output:
a
v
c
