The ICloneable interface creates a copy of the exisiting object i.e a clone.It only has a single method −Clone() − The clone() method creates a new object that is a copy of the current instance.The following is an example showing how to perform cloning using Icloneable interface −Example Live Demousing System; class Car : ICloneable { int width; public Car(int width) { this.width = width; } public object Clone() { return new Car(this.width); } public override string ToString() { return string.Format("Width of ...

The IList interface has a non-generic collection of objects that can be individually accessed by index.The following are the properties of interface IList in C# −Sr.NoProperty Name & Description1CountGets the number of elements contained in the ICollection.2isFixedSizeGets a value indicating whether the IList has a fixed size.3isReadOnlyGets a value indicating whether the IList is read-only.4isSynchronizedGets a value indicating whether access to the ICollection is synchronized.5Item(Int32)Gets or sets the element at the specified index.The following are the methods of the IList interface −Sr.NoProperty Name & Description1Add(Obj)Adds an item to the IList.2Clear()Removes all items from the IList3Contains(Obj)Whether the list contains a specific ...

The IStructuralComparable interface supports the structural comparison of collection objects. This interface introduced in .NET 4.The following is the syntax −public interface IStructuralComparableIt has a single method −CompareTo(Object, IComparer) − It determines whether the current collection object precedes, occurs in the same position as, or follows another object in the sort order.The compareTo() method determines whether the current collection object is less than, equal to, or greater than the second object in the sort order.Explicit implementations for the IStructuralComparable Interface is provided by −Generic tuple classes (Tuple, Tuple, Tuple,…Array class
To display numbers in the form of Triangle, firstly consider a two dimensional array.int[, ] a = new int[5, 5];For a triangle, you need to consider spaces as shown below −1 1 1 1 2 1 1 3 3 1Then loop through to set the triangle with 1s on the left and right as in the following code −Example Live Demousing System; class Demo { public static void Main() { // two dimensional array int[, ] a = new int[5, 5]; for (int i = 0; i < 5; ...

With C#, you can create an array of integers, chars, etc. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type stored at contiguous memory locations. This type can be integer, char, float, etc.The following is an array declaration showing the datatype usage −datatype[] Name_of_array;Here, datatype is used to specify the type of elements in the array.[ ] specifies the rank of the array. The rank specifies the size of the array.Name_of_array − specifies the name of the array.Set the ... Read More
The conditional statement requires the programmer to specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.The following are the types of conditional statements −Sr.NoStatement & Description1if statementAn if statement consists of a boolean expression followed by one or more statements.2if...else statementAn if statement can be followed by an optional else statement, which executes when the boolean expression is false.3nested if statementsYou can use one ...

The increment operator is ++ operator. If used as prefix on a variable, the value of variable gets incremented by 1. After that the value is returned unlike Postfix operator. It is called Prefix increment operator. In the same way the decrement operator works but it decrements by 1.For example, ++a;The following is an example demonstrating Prefix increment operator −Example Live Demousing System; class Program { static void Main() { int a, b; a = 10; Console.WriteLine(++a); b = a; Console.WriteLine(a); Console.WriteLine(b); } }Output11 11 11
A 2-dimensional array is a list of one-dimensional arrays. Declare it like the two dimensional array shown below −int [, ] aTwo-dimensional arrays may be initialized by specifying bracketed values for each row.int [, ] a = new int [4, 4] { {0, 1, 2, 3} , {4, 5, 6, 7} , {8, 9, 10, 11} , {12, 13, 14, 15} };The following is an example showing how to work with two-dimensional arrays in C# −Example Live Demousing System; namespace ArrayApplication { class MyArray { static void Main(string[] args) { /* an ...

The "var" keyword initializes variables with var support. Just assign whatever value you want for the variable, integer, string, float, etc.Example Live Demousing System; namespace Demo { class Program { static void Main(string[] args) { var myInt = 5; var myString = "Amit"; Console.WriteLine("Rank: {0} Name: {1}",myInt,myString); } } }OutputRank: 5 Name: AmitWe can also use var in arrays −Example Live Demousing System; namespace Demo { class Program { static void Main(string[] args) { var myInt = new int[] {65,43,88,56}; foreach(var val in myInt) Console.WriteLine(val); } } }Output65 43 88 56
The Abort() method is used for destroying threads.The runtime aborts the thread by throwing a ThreadAbortException. This exception cannot be caught, the control is sent to the finally block, if any.The following is an example showing how to destroy threads −Example Live Demousing System; using System.Threading; namespace MultithreadingApplication { class ThreadCreationProgram { public static void CallToChildThread() { try { Console.WriteLine("Child thread starts"); // do some work, like counting to 10 for (int counter = 0; counter
