Let’s say the following is the string −StringBuilder str = new StringBuilder("Patience is key!");To remove whitespace, you can use the replace method.str.Replace(" ", "");Let us see the complete code.Example Live Demousing System; using System.Text; class Demo { static void Main() { // Initial String StringBuilder str = new StringBuilder("Patience is key!"); Console.WriteLine(str.ToString()); // Replace str.Replace(" ", ""); // New String Console.WriteLine(str.ToString()); Console.ReadLine(); } }OutputPatience is key! Patienceiskey!
To represent Int632as a Binary string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e. 2 for Binary.Int32 represents a 32-bit signed integer.Firstly, set an Int64 variable −int val = 30;Now, convert it to a binary string by including 2 as the second parameter.Convert.ToString(val, 2)Example Live Demousing System; class Demo { static void Main() { int val = 30; Console.WriteLine("Integer: "+val); Console.Write("Binary String: "+Convert.ToString(val, 2)); } }OutputInteger: 30 Binary String: 11110
With C#, we can easily convert a ValueTuple to a Tuple using ToTuple() method.Note − Add System.ValueTuple package to run ValueTuple program.Let’s see how to add it −Go to your projectRight click on the project in the solution explorerSelect “Manage NuGet Packages”You will reach the NuGet Package Manager.Now, click the Browse tab and find “ValueTuple”Finally, add System.ValueTuple packageExampleusing System; class Program { static void Main() { var val = (5, 50, 500, 5000); //Add System.ValueTuple package to run this program // ValueTuple Console.WriteLine(“ValueTuple: ” val); // Tuple Tuple myTuple = val.ToTuple(); Console.WriteLine(“Tuple: ”+myTuple); } }OutputValueTuple: (5, 50, 500, 5000) Tuple: (5, 50, 500, 5000)
The loadable kernel modules in an operating system is an object file that contains code to extend the running kernel, which is also known as the base kernel. The loadable kernel modules are used to add support for file systems, hardware, system calls etc.An image that shows the loadable modules of the operating system is as follows −The different types of kernels in the operating system that may require loadable kernel modules are −MicrokernelA microkernel is the minimum software that is required to correctly implement an operating system. This includes memory, process scheduling mechanisms and basic inter-process communication.The microkernel contains ... Read More
Firstly, set two lists in C#.List OneList list1 = new List (); list1.Add("P"); list1.Add("Q"); list1.Add("R"); list1.Add("S"); list1.Add("T"); list1.Add("U"); list1.Add("V"); list1.Add("W");List TwoList list2 = new List (); list2.Add("T"); list2.Add("U"); list2.Add("V"); list2.Add("W");Now, to get the different values in both the lists, use the Except method. It returns the values in the first list which is not present in the second list.Example Live Demousing System; using System.Collections.Generic; using System.Linq; public class Demo { public static void Main() { List list1 = new List (); list1.Add("P"); list1.Add("Q"); ...

Set two arrays.var val = new [] { 20, 40, 60}; var str = new [] { "ele1", "ele2", "ele3"};Use the zip() method to process the two arrays in parallel.var res = val.Zip(str, (n, w) => new { Number = n, Word = w });The above fetches both the arrays with int and string elements respectively.Now, use foreach to iterate the two arrays −Example Live Demousing System; using System.Collections.Generic; using System.Linq; public class Demo { public static void Main() { var val = new [] { 20, 40, 60}; var str = new ...

To fetch the consecutive 1’s, use the Bitwise Left Shift Operator. Here is our decimal number.i = (i & (i
Use Hashset to remove duplicate characters.Here is the string −string myStr = "kkllmmnnoo";Now, use HashSet to map the string to char. This will remove the duplicate characters from a string.var unique = new HashSet(myStr);Let us see the complete example −Example Live Demousing System; using System.Linq; using System.Collections.Generic; namespace Demo { class Program { static void Main(string[] args) { string myStr = "kkllmmnnoo"; Console.WriteLine("Initial String: "+myStr); var unique = new HashSet(myStr); Console.Write("New String after removing duplicates: "); foreach (char c in unique) Console.Write(c); } } }OutputInitial String: kkllmmnnoo New String after removing duplicates: klmno
To validate, you need to check for the protocols.http httpsWith that, you need to check for .com, .in, .org, etc.For this, use the following regular expression −(http|http(s)?://)?([\w-]+\.)+[\w-]+[.com|.in|.org]+(\[\?%&=]*)?The following is the code −Example Live Demousing System; using System.Text.RegularExpressions; namespace RegExApplication { class Program { private static void showMatch(string text, string expr) { Console.WriteLine("The Expression: " + expr); MatchCollection mc = Regex.Matches(text, expr); foreach (Match m in mc) { Console.WriteLine(m); } } ...

The following is our string −string myStr = "5";To check whether the above is a string with numeric representation, use TryParse and out.int.TryParse(myStr, out a);Here is the complete code.Example Live Demousing System.IO; using System; class Program { static void Main() { bool res; int a; string myStr = "5"; // checking for valid string representation of a number res = int.TryParse(myStr, out a); Console.WriteLine(res); } }OutputTrue
