To copy or clone a C# list, firstly set a list.List < string > myList = new List < string > (); myList.Add("One"); myList.Add("Two");Now declare a string array and use the CopyTo() method to copy.string[] arr = new string[10]; myList.CopyTo(arr);Let us see the complete code to copy a list into a one-dimensional array.Exampleusing System; using System.Collections.Generic; using System.Linq; public class Demo {    public static void Main() {       List < string > myList = new List < string > ();       myList.Add("One");       myList.Add("Two");       myList.Add("Three");       myList.Add("Four"); ...

Using Synchronization, you can synchronize access to resources in multithreaded applications.A mutex can be used to synchronize threads across processes Use it to prevent the simultaneous execution of a block of code by more than one thread at a time.C# lock statement is used to ensure that a block of code runs without interruption by other threads. A Mutual-exclusion lock is obtained for a given object for the duration of the code block.Thread pool in C# is a collection of threads. It is used to perform tasks in the background. When a thread completes a task, it is sent to ... Read More

Firstly, set a string array.string[] values = { "tim", "amit", "tom", "jack", "saurav"};Use the Sort() method to sort.Array.Sort(values);Let us see the complete code −Example Live Demousing System; public class Program {    public static void Main() {       string[] values = { "tim", "amit", "tom", "jack", "saurav"};       foreach (string value in values) {          Console.Write(value);          Console.Write(' ');       }       // sorting       Array.Sort(values);       Console.WriteLine("Sorted...");       foreach (string value in values) {          Console.Write(value);          Console.Write(' ');       }       Console.WriteLine();    } }Outputtim amit tom jack saurav Sorted... amit jack saurav tim tom

Set a stack and add elements to it.Stack st = new Stack(); st.Push('P'); st.Push('Q'); st.Push('R');Now set another stack to reverse it.Stack rev = new Stack();Until the count of ths Stack is not equal to 0, use the Push and Pop method to reverse it.while (st.Count != 0) {    rev.Push(st.Pop()); }The following is the complete code −Example Live Demousing System; using System.Collections; namespace CollectionsApplication {    public class Program {       public static void Main(string[] args) {          Stack st = new Stack();          Stack rev = new Stack();       ...

The .NET Framework 4 brought the System.Collections.Concurrent namespace. This has several collection classes that are thread-safe and scalable. These collections are called concurrent collections because they can be accessed by multiple threads at a time.The following are the concurrent collection in C# −Sr.NoType & Description1BlockingCollectionBounding and blocking functionality for any type.2ConcurrentDictionaryThread-safe implementation of a dictionary of key-value pairs.3ConcurrentQueueThread-safe implementation of a FIFO (first-in, first-out) queue.4ConcurrentStackThread-safe implementation of a LIFO (last-in, first-out) stack.5ConcurrentBagThread-safe implementation of an unordered collection of elements.6IProducerConsumerCollectionThe interface that a type must implement to be used in a BlockingCollectionLet us see how to work with ConcurrentStack that is ...

In VB, a module is used to store loose code accessible from elsewhere in the application without having to first initialize something.The state of the variable can be easily set or changed and that continues to carry on that value throughout.For the same work in C#< use a static class.Let us see an example −VBModule MyModule Public Sub Display MsgBox("Demo!") End Sub End ModuleC#public static class Display {    public static void DisplayMethod() {       Console.WriteLine("Demo!");    } }
