How Can I Efficiently Repeat a String Multiple Times in C#?

Simplifying String Repetition with String Builders

The task of inserting indentations before a string can be simplified by repeating a string a specified number of times. To efficiently achieve this, consider utilizing the String.Repeat method.

String.Repeat
The String.Repeat method takes a single string parameter and an integer representing the desired number of repetitions. It returns a new string with the original string concatenated upon itself the specified number of times.

Usage
Here's an example of using String.Repeat to create a variable number of indentations:

// Define the indentation string
string indent = "---";

// Repeat the indentation string based on an item's depth
int depth = 3;
string indentation = indent.Repeat(depth);

// Display the indented string
Console.WriteLine(indentation + "Example String");

In this example, the indentation variable is assigned a string with three dashes, and the indented string is displayed with three levels of indentation.

String Constructor
An alternative approach for repeating a single character is using the String constructor that takes a character and the number of repetitions.

// Repeat a dash five times
char dash = '-';
int repetitions = 5;
string result = new String(dash, repetitions);

This approach is particularly convenient when repeating a single non-alphanumeric character, resulting in a string of a specified length filled with the character.
