The Stack.Equals() method in C# is used to check whether a Stack class object is equal to another object or not.SyntaxThe syntax is as follows −public virtual bool Equals (object ob);Above, the parameter ob is the object compared with another.ExampleLet us now see an example − Live Demousing System; using System.Collections; public class Demo {    public static void Main(){       Stack stack = new Stack();       stack.Push(150);       stack.Push(300);       stack.Push(500);       stack.Push(750);       stack.Push(1000);       stack.Push(1250);       stack.Push(1500);       stack.Push(2000);   ...

The TimeSpan.FromDays() method in C# is used to return a TimeSpan that represents a specified number of days, where the specification is accurate to the nearest millisecond.SyntaxThe syntax is as follows −public static TimeSpan FromDays (double val);Above, the parameter val is the number of days, accurate to the nearest millisecond.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(){       TimeSpan span1 = new TimeSpan(5, 25, 0);       TimeSpan span2 = new TimeSpan(1, 10, 0);       TimeSpan span3 = TimeSpan.FromDays(43.999999);       Console.WriteLine("TimeSpan1 = "+span1); ...

The BitConverter.ToUInt64() method in C# is used to return a 64-bit unsigned integer converted from eight bytes at a specified position in a byte array.Syntaxpublic static ulong ToUInt64 (byte[] val, int begnIndex);ExampleAbove, val is the byte array, whereas begnIndex is the beginning position within val. Live Demousing System; public class Demo {    public static void Main() {       byte[] arr = { 0, 0, 1, 3, 5, 7, 9, 11, 15 };       int count = arr.Length;       Console.Write("Byte Array... ");       for (int i = 0; i < count; i++) { ... Read More

The BitConverter.ToUInt32() method in C# is used to return a 32-bit unsigned integer converted from four bytes at a specified position in a byte array.Syntaxpublic static uint ToUInt32 (byte[] val, int begnIndex);Above, val is the byte array, whereas begnIndex is the starting position withing val.Example Live Demousing System; public class Demo {    public static void Main() {       byte[] arr = { 0, 3, 5, 10, 15, 2};       int count = arr.Length;       Console.Write("Byte Array... ");       for (int i = 0; i < count; i++) {         ... Read More

There are two string operators in C#: Equality and Inequality.ExampleLet us see an example of Equality operator − Live Demousing System; public class Demo {    public static void Main() {       string str1 = "Amit";       string str2 = " ";       Console.WriteLine("Is string1 null or empty? = "+string.IsNullOrEmpty(str1));       Console.WriteLine("Is string2 null or empty? = "+string.IsNullOrEmpty(str2));       Console.WriteLine("Is string1 equal to str2? = "+str1 == str2);    } }OutputIs string1 null or empty? = False Is string2 null or empty? = False FalseExampleLet us now see an example of C# Inequality operator − Live Demousing System; public class Demo {    public ...
