The Double.Equals() method in C# is used to return a value indicating whether two instances of Double represent the same value.SyntaxThe syntax is as follows −public bool Equals (double obj); public override bool Equals (object ob);The obj parameter of the first syntax is a Double object to compare to this instance, whereas the obj of the second parameter is an object to compare with this instance.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main() {       double d1 = 150d;       double d2 = 150d;     ...

The Double.CompareTo() method in C# is used to compare this instance to a specified object or Double object and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the specified object or Double object.SyntaxThe syntax is as follows −public int CompareTo (double val); public int CompareTo (object val);Above, the value val in the 1st syntax is a double-precision floating-point number to compare, whereas val for the 2nd syntax is an object to compare.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main() { ...

The Stack.Count property in C# is used to get the number of elements contained in the Stack.SyntaxThe syntax is as follows −public virtual int Count { get; }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("Inspiron");       stack.Push("Alienware");       stack.Push("Projectors");       stack.Push("Monitors");       stack.Push("XPS");       stack.Push("Laptop");       stack.Push("Notebook");       Console.WriteLine("Stack elements...");       foreach(string val in stack) {       ...

The Stack.Contains() method in C# is used to check whether an element is in the Stack or not.SyntaxThe syntax is as follows −public virtual bool Contains (object ob);Above, ob is the object to be searched in the stack.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("Inspiron");       stack.Push("Alienware");       stack.Push("Projectors");       stack.Push("Monitors");       stack.Push("XPS");       stack.Push("Laptop");       stack.Push("Notebook");       Console.WriteLine("Stack elements...");   ...

The TimeSpan.FromMilliseconds() method in C# is used to return a TimeSpan that represents a specified number of milliseconds.The syntax is as follows −Syntaxpublic static TimeSpan FromMilliseconds (double val);Above, val is the number of milliseconds.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main() {       TimeSpan span1 = TimeSpan.FromDays(15);       TimeSpan span2 = new TimeSpan(5, 15, 30);       TimeSpan span3 = TimeSpan.FromHours(5);       TimeSpan span4 = TimeSpan.FromMilliseconds(876876876.1);       Console.WriteLine("TimeSpan1 = "+span1);       Console.WriteLine("TimeSpan2 = "+span2);       Console.WriteLine("TimeSpan3 = ... Read More

The String.IsNormalized() method in C# is used to indicate whether this string is in a particular Unicode normalization form.SyntaxThe syntax is as follows −public bool IsNormalized (); public bool IsNormalized (System.Text.NormalizationForm normalizationForm);Above, the parameter normalizationForm is a Unicode normalization form.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(String[] args) {       string str1 = "Ryan";       string str2 = "Matt";       Console.WriteLine("String 1 = "+str1);       Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode());       Console.WriteLine("Index of character 'k' in str1 = " ... Read More

The String.IndexOf() method in C# is used to find the zero-based index of the first occurrence of a specified Unicode character or string within this instance.SyntaxThe syntax is as follows −public int IndexOf (string val);Above, val is the string to find.ExampleLet us now see an example − Live Demousing System; public class Demo {    public static void Main(String[] args) {       string str1 = "Jacob";       string str2 = "John";       Console.WriteLine("String 1 = "+str1);       Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode());       Console.WriteLine("Index of character 'o' is str1 = ...
