StringBuilder from System.Text namespace is a mutable string.
The following code appends strings to StringBuilder.
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.Append(s);
}
Console.WriteLine(sb);
}
}
The output:
avc
Using Append method from StringBuilder is more efficient than using + to add strings together.
