C# ToCharArray() मेथड

C# में ToCharArray() मेथड इस इंस्टेंस में कैरेक्टर्स को एक यूनिकोड कैरेक्टर ऐरे में कॉपी करने के लिए उपयोग किया जाता है।

सिंटैक्स

सिंटैक्स इस प्रकार है -

public char[] ToCharArray (); public char[] ToCharArray (int begnIndex, int len);

उपरोक्त, begnIndex इस इंस्टेंस में एक सबस्ट्रिंग की शुरुआती स्थिति है। len इस इंस्टेंस में सबस्ट्रिंग की लंबाई है।

उदाहरण 1

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("\n\nString2 = " + 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]);
    }
}
