उदाहरण 1

using System;

public class Demo {
    public static void Main() {
        string str1 = "h8b9";
        string str2 = "abcdef";
        Console.WriteLine("Is string1 null or empty? = " + string.IsNullOrEmpty(str1));
        Console.WriteLine("Is string2 null or empty? = " + string.IsNullOrEmpty(str2));
        bool val = str1 != str2;
        Console.WriteLine("Is str1 equal to str2? = " + val);
        for (int i = 0; i < str1.Length; i++) {
            if (Char.IsLetter(str1[i]))
                Console.WriteLine("" + str1[i] + " is a letter");
            else
                Console.WriteLine("" + str1[i] + " is a number");
        }
    }
}

आउटपुट

Is string1 null or empty? = False
Is string2 null or empty? = False
Is str1 equal to str2? = True
h is a letter
8 is a number
b is a letter
9 is a number

उदाहरण 2

public class Demo {
    public static void Main() {
        string str1 = "hijklm";
        string str2 = String.Empty;
        Console.WriteLine("Is string1 null or whitespace? = " + String.IsNullOrWhiteSpace(str1));
        Console.WriteLine("Is string2 null or whitespace? = " + String.IsNullOrWhiteSpace(str2));
        Console.WriteLine("String1 length = " + str1.Length);
        Console.WriteLine("String2 length = " + str1.Length);
        Console.WriteLine("String length = " + "demo".Length);
    }
}
