We all work with string values in our daily programming life. Sometimes we might require a string variable to be initialized with strings of a repeated character.

Now let us come to the point.

.NET Framework String class already have a parameterized constructor to do the same.

String Constructor (Char, Int32)

C# Syntax:

public String(
 char c,
 int count
 )

MSDN: “Initializes a new instance of the String class to the value indicated by a specified Unicode character repeated a specified number of times.”

See the sample usage given below,

class Program
{
	static void Main(string[] args)
	{
		int size = 10;

		string sample = new String('-', size);

		Console.WriteLine(sample);

		Console.ReadKey();

		//Outputs : ----------
	}
}

This is the most straightforward and efficient way to initialize a string variable with strings of repeated characters.
