Step 4: Return Length
STOP

C# Program to Find the Length of a String

using System;  
public class LFC
{  
	public static void Main() 
	{
		string str1="Letsfindcourse"; /* Declares a string of size 100 */
		int l= 0;
		foreach(char chr in str1)
		{
			l += 1;
		}
		Console.Write("Length of the string = {0}\n\n", l);
	}
}

Output

Length of the string = 14
