How to copy specified number of characters from a string into character array in C#?

C# - Copy specified number of characters from a string into character array: Here, we will learn how we can copy number of character from given position of the string into character array in C#.Net using string.CopyTo() method?

Given a string and we have to copy number of character from given position to character array in C#.Net.

To copy specified number characters of string to character array .NET framework provides built in method, which is:

string.CopyTo(int sourceIndex, char []destArray, int destIndex , int totalChar);

Here,
sourceIndex : It is the index of string from which we are copying characters to character array.
destArray : It is a character array, in which we are copying characters form string.
destIndex : It is index of destination character array.
totalChar : It specifies, how many characters will we copied.

Consider the program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main()
		{
			//string
			string str = "Hello, How are you ?";

			int i = 0;
			//charcater array declaration
			char[] CH = new char[11];

			//copying 11 characters from 7th index
			str.CopyTo(7, CH, 0, 11);

			//printing character by character
			for (i = 0; i < CH.Length;i++ )
			{
				Console.Write(CH[i] + "");
			}

			Console.WriteLine();
		}
	}
}
