Set the string you want to split.string str = "Hello World!";Use the split() method to split the string into separate elements.string[] res = str.Split(' ');The following is the complete code to split a string into elements of a string array in C#.Example Live Demousing System; class Demo {    static void Main() {       string str = "Hello World!";       string[] res = str.Split(' ');       Console.WriteLine("Separate elements:");       foreach (string words in res) {          Console.WriteLine(words);       }    } }OutputSeparate elements: Hello World!

Set the list of dictionaries with keys and values.var d = new Dictionary(); d.Add("Zack", 0); d.Add("Akon", 3); d.Add("Jack", 2); d.Add("Tom", 1);Get and sort the keys.var val = d.Keys.ToList(); val.Sort();You can try to run the following code to sort a list of dictionaries by values.Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Demo {    static void Main() {       var d = new Dictionary();       d.Add("Zack", 0);       d.Add("Akon", 3);       d.Add("Jack", 2);       d.Add("Tom", 1);       // Acquire keys and sort them.       var val ...

Firstly, set a list in C#.var list = new List{ "one","two","three","four"};Now get the count of the elements and display randomly.int index = random.Next(list.Count); Console.WriteLine(list[index]);To select a random element from a list in C#, try to run the following code −Example Live Demousing System; using System.Collections.Generic; namespace Demo {    class Program {       static void Main(string[] args) {          var random = new Random();          var list = new List{ "one","two","three","four"};          int index = random.Next(list.Count);          Console.WriteLine(list[index]);       }    } }Outputthree

WriteLine() is a method of the Console class defined in the System namespaceThis statement causes the message "Welcome!" to be displayed on the screen as shown below −Example Live Demousing System; namespace Demo {    class Test {       static void Main(string[] args) {          Console.WriteLine("Welcome!");          Console.ReadKey();       }    } }OutputWelcome!To display a char array using the Console.WriteLine.Example Live Demousing System; namespace Demo {    class Test {       static void Main(string[] args) {          char[] arr = new char[] { 'W', 'e'};          Console.WriteLine(arr);          Console.ReadKey();       }    } }OutputWe

Serialization/ De-serialization allow communication with another application by sending and receiving data. With XmlSerializer, you can control how objects are encoded into XML. To perform XML Serialization, you need the following two classes − StreamWriter class XmlSerializer class Call the Serialize method with the parameters of the StreamWriter and object to serialize. string myPath = "new.xml"; XmlSerializer s = new XmlSerializer(settings.GetType()); StreamWriter streamWriter = new StreamWriter(myPath); s.Serialize(streamWriter, settings); An XML file is visible with the name “new.xml”. Now to deserialize. MySettings mySettings = new MySettings(); string myPath = "new.xml"; XmlSerializer ... Read More

The ToString() method returns a string that represents the current object.In the below example, we have used the ToString() method with another Array class method.arr.GetLowerBound(0).ToString()Example Live Demousing System; using System.Collections.Generic; using System.Linq; using System.Text; namespace lower {    class Program {       static void Main(string[] args) {          Array arr = Array.CreateInstance(typeof(String), 3);          arr.SetValue("One", 0);          arr.SetValue("Two", 1);          Console.WriteLine("Lower Bound {0}",arr.GetLowerBound(0).ToString());          Console.ReadLine();       }    } }OutputLower Bound 0

The Sort() method sorts the elements in an entire one-dimensional Array using the IComparable implementation of each element of the Array.Set the array.int[] list = { 22, 12, 65, 9};Use the Sort() method to sort the array.Array.Sort(list);The following is an example to learn how to work with the Sort() method.Example Live Demousing System; namespace Demo {    class Program {       static void Main(string[] args) {          int[] list = { 22, 12, 65, 9};          Console.Write("Original Array: ");          foreach (int i in list) {         ...

Declare Jagged ArrayA Jagged array is an array of arrays. You can declare a jagged array named scores of type int as −int [][] points;Initialize Jagged ArrayLet us now see how to initialize it.int[][] points = new int[][]{new int[]{10, 5}, new int[]{30, 40}, new int[]{70, 80}, new int[]{ 60, 70 }};Access the Jagged Array ElementAccess the jagged array element as.points[i][j]);The following is the complete example showing how to work with jagged arrays in C#.Example Live Demousing System; namespace ArrayApplication {    class MyArray {       static void Main(string[] args) {          int[][] points = new int[][]{new ...

Set the unsorted array first.int[] list = {87, 45, 56, 22, 84, 65};Now use a nested for loop to sort the list, which is passed to a function.for(int i=0; i< arr.Length; i++) {    for(int j=i+1; j=arr[j]) {          temp=arr[j];          arr[j]=arr[i];          arr[i]=temp;       }    }    Console.Write(arr[i] + " "); }The following is the complete code to sort one-dimensional array in ascending order using non-static method.Example Live Demousing System; namespace Demo {    public class MyApplication {       public static void Main(string[] args) {   ...

The return statement is used to return value. When a program calls a function, the program control is transferred to the called function. A called function performs a defined task and when its return statement is executed or when its function-ending closing brace is reached, it returns the program control back to the main program.The following is an example to learn about the usage of return statement in C#. Here, we are finding the factorial of a number and returning the result using the return statement.while (n != 1) {    res = res * n;    n = n ... Read More
