Repeating a String for Indentation

When indenting a string based on an item's depth, it's convenient to have an efficient way to return a string repeated a specified number of times.

Using the String Constructor

If you only intend to repeat the same character, you can use the String constructor that accepts a character and the number of times to repeat it:

string indent = new String(char c, int count);

For example, to create an indentation string of five hyphens:

string indent = new String('-', 5);

This will return the string "-----".

Example Usage

You can use this approach to easily generate indentations based on an item's depth:

int depth = 2;
string indent = new String('-', depth);
Console.WriteLine(indent   "Item at depth "   depth);

Output:
--Item at depth 2
