We have a sample string with spaces −str ="Hello World !";Use the Replace() method in C# to replace all spaces in a string with ‘%20’ −str2 = str.Replace(" ", "%20");ExampleYou can try to run the following code to replace all spaces in a string with ‘%20’.Live Demousing System; class Demo {    static void Main() {       String str, str2;       str ="Hello World !";       Console.WriteLine("String: "+str);       str2 = str.Replace(" ", "%20");       Console.WriteLine("String (After replacing): "+str2);    } }OutputString: Hello World ! String (After replacing): Hello%20World%20!

Firstly, initialize three sorted arrays −int []one = {20, 35, 57, 70}; int []two = {9, 35, 57, 70, 92}; int []three = {25, 35, 55, 57, 67, 70};To find common elements in the three-sorted arrays, iterate through the arrays using a while loop and check the first array with a second and second array with the third −while (i < one.Length && j < two.Length && k < three.Length) {    if (one[i] == two[j] && two[j] == three[k]) {       Console.Write(one[i] + " ");       i++;j++;k++;    }    else if (one[i] < two[j]) ...

To find the hostname, use the Dns.GetHostName() method in C# −String hostName = string.Empty; hostName = Dns.GetHostName(); Console.WriteLine("Hostname: "+hostName);Now, use the IPHostEntry.AddressList Property to get IP Address −IPHostEntry myIP = Dns.GetHostEntry(hostName); IPAddress[] address = myIP.AddressList;ExampleTry the following code to display hostname and IP address −using System; using System.Net; class Program {    static void Main() {       String hostName = string.Empty;       hostName = Dns.GetHostName();       Console.WriteLine("Hostname: "+hostName);       IPHostEntry myIP = Dns.GetHostEntry(hostName);       IPAddress[] address = myIP.AddressList;       for (int i = 0; i < address.Length; i++) {          Console.WriteLine("IP Address {1} : ",address[i].ToString());       }       Console.ReadLine();    } }

Firstly, create a new linked list −LinkedList myList = new LinkedList();Now add some elements in the linked list −// Add 6 elements in the linked list myList.AddLast("P"); myList.AddLast("Q"); myList.AddLast("R"); myList.AddLast("S"); myList.AddLast("T"); myList.AddLast("U");Let’s now find a node and add a new node after that −LinkedListNode node = myList.Find("R"); myList.AddAfter(node, "ADDED");ExampleYou can try to run the following code to find a node in the linked list.Live Demousing System; using System.Collections.Generic; class Program {    static void Main() {       LinkedList myList = new LinkedList();       // Add 6 elements in the linked list       myList.AddLast("P");   ...

To count uppercase characters in a string, check the following condition −myStr[i]>='A' && myStr[i]='a' && myStr[i]

Use the substring() method in C# to find all substrings in a string.Let’s say our string is −XyzLoop through the length of the string and use the Substring function from the beginning to the end of the string −for (int start = 0; start

Firstly, enter the number for which you want the factors −Console.WriteLine("Enter the Number:"); n = int.Parse(Console.ReadLine());After that, loop through to find the factors −for (i = 1; i

To show the priority of the thread in C#, use the Priority property.Firstly, use the currentThread property to display information about a thread −Thread thread = Thread.CurrentThread;Now use the thread.Priority property to display the priority of the thread −thread.PriorityExampleLet us see the complete code to show the thread’s priority in C#.Live Demousing System; using System.Threading; namespace Demo {    class MyClass {       static void Main(string[] args) {          Thread thread = Thread.CurrentThread;          thread.Name = "My Thread";          Console.WriteLine("Thread Priority = {0}", thread.Priority);          Console.ReadKey();       }    } }OutputThread Priority = Normal

To display the name of the current thread in C#, use the Name property.Firstly, use the currentThread property to display information about a thread −Thread thread = Thread.CurrentThread;Now use the thread.Name property to display name of the thread −thread.NameExampleLet us see the complete code show current thread’s name in C#.Live Demousing System; using System.Threading; namespace Demo {    class MyClass {       static void Main(string[] args) {          Thread thread = Thread.CurrentThread;          thread.Name = "My Thread";          Console.WriteLine("Thread Name = {0}", thread.Name);          Console.ReadKey();       }    } }OutputThread Name = My Thread

You need to check for both the vowels and consonants, but do not forget to check for both the uppercase as well lowercase.For counting vowels, check for “aeiou” characters separately i.e.if (myStr[i] == 'a' || myStr[i] == 'e' || myStr[i] == 'i' || myStr[i] == 'o' || myStr[i] == 'u' || myStr[i] == 'A' || myStr[i] == 'E' || myStr[i] == 'I' || myStr[i] == 'O' || myStr[i] == 'U') {    vowel_count++; }ExampleThe following is the code to count the number of Vowels in a string.Live Demousing System; public class Demo {    public static void Main() {   ...
