Efficient Loop Buffering

Snippet

Efficient Loop Buffering

Using StringBuilder is significantly faster than standard string concatenation (+) when modifying text inside a loop.

snippet.cs

csharp

using System.Text;
 
public class Program {
    public static void Main() {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < 5; i++) {
            sb.Append("Item ").Append(i).Append(" ");
        }
        System.Console.WriteLine(sb.ToString());
    }
}

Breakdown

StringBuilder sb = new StringBuilder()

Initializes a mutable string buffer to store characters efficiently.

sb.Append(i)

Adds the current value to the end of the buffer without creating a new string object.
