// C# program demonstrate
// the Chars[Int32] Property
using System;
using System.Text;
class GFG {
// Main Method
public static void Main(String[] args)
{
// create a StringBuilder object
// with a String pass as parameter
StringBuilder str =
new StringBuilder("GeeksforGeeks");
// print string
Console.WriteLine("String is "
+ str.ToString());
// loop through string
// and print every Character
for (int i = 0; i < str.Length; i++) {
// get char at position i
char ch = str[i];
// print char
Console.WriteLine("Char at position "
+ i + " is " + ch);
}
}
}
Output:
Example 2:
String is GeeksforGeeks Char at position 0 is G Char at position 1 is e Char at position 2 is e Char at position 3 is k Char at position 4 is s Char at position 5 is f Char at position 6 is o Char at position 7 is r Char at position 8 is G Char at position 9 is e Char at position 10 is e Char at position 11 is k Char at position 12 is s
