C# ToCharArray() Method
The ToCharArray() method in C# is used to copy the characters in this instance to a Unicode character array.
Syntax
The syntax is as follows -
public char[] ToCharArray (); public char[] ToCharArray (int begnIndex, int len);
Above, begnIndex is the beginning position of a substring in this instance. The len is the length of the substring in this instance.
Example
Let us now see an example -
using System; public class Demo { public static void Main(String[] args) { string str1 = "Notebook"; string str2 = "Ultrabook"; char[] arr1 = str1.ToCharArray(); char[] arr2 = str2.ToCharArray(); Console.WriteLine("String1 = "+str1); Console.WriteLine("String1 ToUpperInvariant = "+str1.ToUpperInvariant()); Console.WriteLine("String1 Substring from index4 = " + str1.Substring(4, 4)); Console.Write("Character array...String1 ="); for (int i = 0; i < arr1.Length; i++) Console.Write(" " + arr1[i]); Console.WriteLine("
String2 = "+str2); Console.WriteLine("String2 ToUpperInvariant = "+str2.ToLowerInvariant()); Console.WriteLine("String2 Substring from index2 = " + str2.Substring(0, 5)); Console.Write("Character array...String2 ="); for (int i = 0; i < arr2.Length; i++) Console.Write(" " + arr2[i]); } }
Output
String1 = Notebook String1 ToUpperInvariant = NOTEBOOK String1 Substring from index4 = book Character array...String1 = N o t e b o o k String2 = Ultrabook String2 ToUpperInvariant = ultrabook String2 Substring from index2 = Ultra Character array...String2 = U l t r a b o o k
Example
using System; public class Demo { public static void Main(String[] args) { string str1 = "Welcome!"; string str2 = "Thisisit!"; char[] arr1 = str1.ToCharArray(3,2); char[] arr2 = str2.ToCharArray(2,2); Console.WriteLine("String1 = "+str1); Console.WriteLine("String1 ToUpperInvariant = "+str1.ToUpperInvariant()); Console.WriteLine("String1 Substring from index4 = " + str1.Substring(4, 4)); Console.Write("Character array...String1 ="); for (int i = 0; i < arr1.Length; i++) Console.Write(" " + arr1[i]); Console.WriteLine("
String2 = "+str2); Console.WriteLine("String2 ToUpperInvariant = "+str2.ToLowerInvariant()); Console.WriteLine("String2 Substring from index2 = " + str2.Substring(0, 5)); Console.Write("Character array...String2 ="); for (int i = 0; i < arr2.Length; i++) Console.Write(" " + arr2[i]); } }
Output
This will produce the following output -
String1 = Welcome! String1 ToUpperInvariant = WELCOME! String1 Substring from index4 = ome! Character array...String1 = c o String2 = Thisisit! String2 ToUpperInvariant = thisisit! String2 Substring from index2 = Thisi Character array...String2 = i s
