Use the CSS :checked selector to style every checked element. You can try to run the following code to implement the :checked selector:ExampleLive Demo input:checked { height: 20px; width: 20px; } Fav sports: Football Cricket Tennis Tennis Output
The SequenceEqual method is used to test collections for equality.Let us set three string arrays −string[] arr1 = { "This", "is", "it" }; string[] arr2 = { "My", "work", "report" }; string[] arr3 = { "This", "is", "it" };Now, compare the first array with the second using the SequenceEqual() method −arr1.SequenceEqual(arr2);The following is an example −Example Live Demousing System; using System.Linq; class Program { static void Main() { string[] arr1 = { "This", "is", "it" }; string[] arr2 = { "My", "work", "report" }; string[] arr3 = { "This", "is", "it" }; bool res1 = arr1.SequenceEqual(arr2); Console.WriteLine(res1); bool res2 = arr1.SequenceEqual(arr3); Console.WriteLine(res2); } }OutputFalse True
Set a string array and convert it to character array −string str = "Amit"; char[] arr = str.ToCharArray();Now, use the Reverse method to display the above string in reverse alphabetic order −Array.Reverse(arr);Here is the complete code −Example Live Demousing System; using System.Linq; using System.IO; class Program { static void Main() { string str = "Amit"; char[] arr = str.ToCharArray(); Console.WriteLine("Original String: "+str); // Reverse Array.Reverse(arr); Console.WriteLine("Reversed String: "+new string(arr)); } }OutputOriginal String: Amit Reversed String: timA
Firstly, set a string −string str = "Science and Mathematics";Now use the Split() method to split wherever the spaces occur −str.Split(' ')The following is the complete code −Example Live Demousing System; using System.Linq; using System.IO; class Program { static void Main() { string str = "Science and Mathematics"; Console.WriteLine("String..."+str); string[] myStr = str.Split(' '); Console.WriteLine("Splitted String..."); foreach (string ch in myStr) { Console.WriteLine(ch); } } }OutputString... Science and Mathematics Splitted String... Science and Mathematics
Firstly, set a string i.e. your Windows directory path −string str = @"D:\Downloads\Amit";Now use the Split() method and split wherever the \ occur −str.Split(' \')The following is the complete code −Example Live Demousing System; class Program { static void Main() { string str = @"D:\Downloads\Amit"; Console.WriteLine("Directory..."+str); string[] myStr = str.Split('\'); Console.WriteLine("Split..."); foreach (string ch in myStr) { Console.WriteLine(ch); } } }OutputDirectory... D:\Downloads\Amit Split... D: Downloads Amit
Let’s say the following is the number −int a = 12250;You can work around the following ways to get a number in hexadecimal format −{0:x} {0:x8} {0:X} {0:X8}Here is the code −Example Live Demousing System; class Demo { static void Main() { int a = 12250; Console.WriteLine("{0:x}", a); Console.WriteLine("{0:x8}", a); Console.WriteLine("{0:X}", a); Console.WriteLine("{0:X8}", a); } }Output2fda 00002fda 2FDA 00002FDA
To create a tuple, use the Tuple.Create method.Here we have set a tuple with a string and int −var myTuple = Tuple.Create("marks", 100);The following is an example that creates a tuple using Tuple.Create and displays the elements in a single line in C# −Example Live Demousing System; class Demo { static void Main() { var myTuple = Tuple.Create("marks", 100); Console.WriteLine(myTuple); } }Output(marks, 100)
With C#, you can easily set a 6-item tuple.The following is a 6-item tuple −var myTuple = new Tuple("electronics", new string[] { "shoes", "clothing#", "accessories" }, 100, 250, 500, 1000);above, we have tuple for string, string array and int as shown below −TupleHere is the complete code −Example Live Demousing System; class Demo { static void Main() { var myTuple = new Tuple("electronics", new string[] { "shoes", "clothing#", "accessories" }, 100, 250, 500, 1000); // Displaying Item 1 Console.WriteLine(myTuple.Item1); // Displaying Item 5 Console.WriteLine(myTuple.Item5); // Displaying Item 6 Console.WriteLine(myTuple.Item6); } }Outputelectronics 500 1000
To get the last write time of a file in C#, use the LastWriteTime() method.For this, use the FileInfo as well as DateTime classes.Create an object of each −FileInfo file = new FileInfo("amit.txt"); DateTime dt = file.CreationTime; dt = file.LastWriteTime;Let us see the complete code −Example Live Demousing System.IO; using System; public class Program { public static void Main() { using (StreamWriter sw = new StreamWriter("amit.txt")) { sw.WriteLine("Welcome!"); } FileInfo file = new FileInfo("amit.txt"); // file creation time DateTime dt = ...

To get the last access time of a file in C#, use the LastAccessTime() method.For this, use the FileInfo as well as DateTime classes.Create an object of each −FileInfo file = new FileInfo("new.txt"); DateTime dt = file.CreationTime; dt = file.LastAccessTime;Let us see the complete code −Example Live Demousing System.IO; using System; public class Program { public static void Main() { using (StreamWriter sw = new StreamWriter("quiz.txt")) { sw.WriteLine("Quizzes!"); } FileInfo file = new FileInfo("quiz.txt"); // last access time DateTime dt = file.LastAccessTime; Console.WriteLine(dt); } }Output9/5/2018 5:21:43 AM
