To check if an array has fixed size or not, try the below code −Example Live Demousing System; public class Demo {    public static void Main(){       string[] products = new string[] { "Electronics", "Accessories", "Clothing", "Toys", "Clothing", "Furniture" };       Console.WriteLine("Products list...");       foreach(string s in products){          Console.WriteLine(s);       }       Console.WriteLine("Is the products Accessories in the array? = {0}",          Array.Exists(products, ele => ele == "Accessories"));       Console.WriteLine("Is the products Stationery in the array? = {0}",       ...

To check if an array contains the elements that match the specific conditions, we can use the StartsWith() method in C# −Example Live Demousing System; public class Demo {    public static void Main(){       string[] products = { "Electronics", "Accessories", "Clothing", "Toys", "Clothing", "Furniture" };       Console.WriteLine("Products list...");       foreach(string s in products){          Console.WriteLine(s);       }       Console.WriteLine("One or more products begin with the letter 'C'? = {0}",       Array.Exists(products, ele => ele.StartsWith("C")));       Console.WriteLine("One or more planets begin with 'D'? = ...

To check if a value is in LinkedList, try the below code −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(){       LinkedList linkedList = new LinkedList();       linkedList.AddLast(25);       linkedList.AddLast(50);       linkedList.AddLast(100);       linkedList.AddLast(200);       linkedList.AddLast(400);       linkedList.AddLast(500);       linkedList.AddLast(550);       linkedList.AddLast(600);       linkedList.AddLast(800);       linkedList.AddLast(1200);       Console.WriteLine("Count of nodes = " + linkedList.Count);       foreach(int val in linkedList){          Console.WriteLine(val);       } ...

To check if a HashSet and a specified collection share a common element, the C# code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(){       HashSet set1 = new HashSet();       set1.Add(25);       set1.Add(50);       set1.Add(75);       set1.Add(100);       set1.Add(125);       set1.Add(150);       Console.WriteLine("Elements in HashSet1");       foreach(int val in set1){          Console.WriteLine(val);       }       HashSet set2 = new HashSet();       set2.Add(30);   ...

The BitConverter class converts base data types to an array of bytes, and an array of bytes to base data types.Following are the methods −MethodDescriptionDoubleToInt64Bits(Double)Converts the specified double-precision floating-point number to a 64-bit signed integer.GetBytes(Boolean)Returns the specified Boolean value as a byte array.GetBytes(Char)Returns the specified Unicode character value as an array of bytes.GetBytes(Double)Returns the specified double-precision floating-point value as an array of bytes.GetBytes(Int16)Returns the specified 16-bit signed integer value as an array of bytes.GetBytes(Int32)Returns the specified 32-bit signed integer value as an array of bytes.Int64BitsToDouble(Int64)Reinterprets the specified 64-bit signed integer to a double-precision floating-point number.ToBoolean(Byte[], Int32)Returns a Boolean value converted ...

The Queue.Contains() method in C# is used to determine whether an element is in the Queue.SyntaxThe syntax is as follows -public virtual bool Contains (object ob);Above, the parameter ob is the Object to locate in the Queue.ExampleLet us now see an example - Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main() {       Queue queue = new Queue();       queue.Enqueue("Gary");       queue.Enqueue("Jack");       queue.Enqueue("Ryan");       queue.Enqueue("Kevin");       queue.Enqueue("Mark");       queue.Enqueue("Jack");       queue.Enqueue("Ryan");       queue.Enqueue("Kevin");       Console.Write("Count ...

The StringBuilder.CopyTo() method in C# is used to copy the characters from a specified segment of this instance to a specified segment of a destination Char array.SyntaxThe syntax is as follows -public void CopyTo (int sourceIndex, char[] dest, int destIndex, int count);Above, the parameter sourceIndex is the starting position in this instance where characters will be copied from. The dest is the array where characters will be copied, whereas the destIndex is the starting position in destination where characters will be copied. The count parameter is the number of characters to be copied.ExampleLet us now see an example - Live Demousing ... Read More

The Queue.Clone() method in C# is used to create a shallow copy of the Queue.SyntaxThe syntax is as follows -public virtual object Clone ();ExampleLet us now see an example - Live Demousing System; using System.Collections; public class Demo {    public static void Main(string[] args) {       Queue queue = new Queue();       queue.Enqueue("One");       queue.Enqueue("Two");       queue.Enqueue("Three");       queue.Enqueue("Four");       queue.Enqueue("Five");       queue.Enqueue("Six");       queue.Enqueue("Seven");       queue.Enqueue("Eight");       Console.WriteLine("Queue...");       foreach(string str in queue) {       ... Read More

The Queue.Clear() method in C# is used to clear all object from Queue.SyntaxThe syntax is as follows -public virtual void Clear ();ExampleLet us now see an example - Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main() {       Queue queue = new Queue();       queue.Enqueue(100);       queue.Enqueue(200);       queue.Enqueue(300);       queue.Enqueue(400);       queue.Enqueue(500);       queue.Enqueue(600);       queue.Enqueue(700);       queue.Enqueue(800);       queue.Enqueue(900);       queue.Enqueue(1000);       Console.WriteLine("Queue...");       foreach(int i in ...

The Double.IsPositiveInfinity() method in C# is used to return a value indicating whether the specified number evaluates to positive infinity.SyntaxThe syntax is as follows -public static bool IsPositiveInfinity (double val);Above, val is a double-precision floating-point number.ExampleLet us now see an example - Live Demousing System; public class Demo {    public static void Main() {       double d = 1.0/0.0;       Console.WriteLine("Double Value = "+d);       Console.WriteLine("HashCode of Double Value = "+d.GetHashCode());       TypeCode type = d.GetTypeCode();       Console.WriteLine("TypeCode of Double Value = "+type);       Console.WriteLine("Positive Infinity? = "+Double.IsInfinity(d)); ...
