To compare dates in C#, you need to first set two dates to be compared using the DateTime object. We will use the DateTime class in C#.Date 1DateTime date1 = new DateTime(2018, 07, 20); Console.WriteLine("Date 1 : {0}", date1);Date 2DateTime date2 = new DateTime(2018, 07, 25); Console.WriteLine("Date 2 : {0}", date2);Now let us compare both the dates in C#. The following is an example to compare dates in C#.Example Live Demousing System; namespace Program { class Demo { static int Main() { DateTime date1 = new DateTime(2018, 07, 20); ... Read More

Enum is Enumeration to store a set of named constants like year, product, month, season, etc.The default value of Enum constants starts from 0 and increments. It has fixed set of constants and can be traversed easily. However you can still change the start index and customize it with the value of your choice.In the following example, I have set the customized value to be 20 instead of the default 0.Example Live Demousing System; public class Demo { public enum Vehicle { Car =20, Motorcycle, Bus, Truck } public static void Main() { int a = ...

Division operator is used in C# to divide numerator by denominator, for example 9/ 3The division operator comes under Arithmetic Operators in C#. Let us see a complete example to learn how to implement Arithmetic operators in C#, wherein we will see how to work with division operator.result = num1 / num2; Console.WriteLine("Division: Value is {0}", result);Above we have used division operator on num1 and num2.The following is the complete example.Example Live Demousing System; namespace Sample { class Demo { static void Main(string[] args) { int num1 = 50; ...

C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972. C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg. The following are the differences between C and C#. Language C language is a structured programming language, whereas C# is an object-orinted language. Memory Management C has manual memory management, whereas memory management is handled automatically in C#. Garbage Collection C do not have ... Read More

IComparable Interface in C#Use the IComparable Interface in C# to sort elements. It is also used to compare the current instance with another object of same type.It provides you with a method of comparing two objects of a particular type. Remember, while implementing the IComparable interface, CompareTo() method should also be implemented.Let us see an example −int IComparable.CompareTo(object ob) { Vehicle v=(Vehicle)ob; return String.Compare(this.make, v.make); }IComparer interface in C#The IComparer interface is used to sort elements that compare two objects and provides additional comparison method.Exampleprivate class sortYearAscendingHelper : IComparer { int IComparer.Compare(object ob1, object ob2) { ...

The IsReadOnly property of Hashtable class is used to get a value indicating whether the Hashtable is read-only.Example Live Demousing System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { Hashtable ht = new Hashtable(); ht.Add("One", "Amit"); ht.Add("Two", "Aman"); ht.Add("Three", "Raman"); Console.WriteLine("IsReadOnly = " + ht.IsReadOnly); Console.ReadKey(); } } }OutputIsReadOnly = FalseAbove we have set a Hashtable with three elements.ht.Add("One", "Amit"); ht.Add("Two", "Aman"); ht.Add("Three", "Raman");After that, we have checked using the IsReadOnly property.Console.WriteLine("IsReadOnly = " + ht.IsReadOnly);

Internal variable is set using the internal access specifier.internal double length; internal double width;Any member with internal access specifier can be accessed from any class or method defined within the application in which the member is defined.Example Live Demousing System; namespace RectangleApplication { class Rectangle { //member variables internal double length; internal double width; double GetArea() { return length * width; } public void Display() { Console.WriteLine("Length: {0}", length); Console.WriteLine("Width: ...

C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg. The following are the differences between C++and C#. Memory Management C++ has manual memory management, whereas memory management is handled automatically in C#. Platforms C++ can be run on different platforms whereas C# is generally used only on Windows. Faster code C++ code ... Read More

Strings in C# String is immutable in C# that would mean you couldn’t modify it after it is created. It creates a new object of string type in memory if you will perform any operation. string str1 = "Welcome!"; // creates a new string instance str1 += "Hello"; str1 += "World”; StringBuilder in C# StringBuilder is mutable in C#. This means that if an operation is performed on the string, it will not create a new instance every time. With that, it will not create new space in memory, unlike Strings. StringBuilder str1 = new StringBuilder(""); str1.Append("Welcome!"); ... Read More
