using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {
     
      string str = "Icecream";
      char[] result;

      // copies str to result
      result = str.ToCharArray();

      // prints result
      for (int i = 0; i < result.Length; i++) {
        Console.Write(result[i] + ", ");
      }

      Console.ReadLine();    
    }
  } 
}

// Output: I, c, e, c, r, e, a, m,

Example 1: C# String ToCharArray()

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {
     
      string str = "Chocolate";
      char[] result;

      // copies str to result
      result = str.ToCharArray();

      // prints result
      for (int i = 0; i < result.Length; i++) {
        Console.WriteLine(result[i]);
      }

      Console.ReadLine();    
    }
  } 
}

Output

C
h
o
c
o
l
a
t
e

Example 2: C# String ToCharArray() With Parameters

using System;  
namespace CsharpString {  
  class Test {
    public static void Main(string [] args) {
     
      string str = "Icecream";
      char[] result;

      // copies 4 chars from index 3 of str
      result = str.ToCharArray(3, 4);

      // prints result
      for (int i = 0; i < result.Length; i++) {
        Console.WriteLine(result[i]);
      }

      Console.ReadLine();    
    }
  } 
}

Output

c
r
e
a

Notice the code,

str.ToCharArray(3, 4) 

Here,

• 3 - starting index to copy characters from
• 4 - length of the string to be copied
