TrimStart() method removes all leading occurrences of a set of characters, whereas TrimEnd()removes all trailing occurrences of a set of characters.TrimStart()The TrimStart() method removes all leading occurrences of a set of characters specified in an array.Let us see an example to remove all leading zeros −Example Live Demousing System; class Program {    static void Main() {       String str ="0009678".TrimStart(new Char[] { '0' } );       Console.WriteLine(str);    } }Output9678TrimEnd()The TrimEnd() method removes all trailing occurrences of a set of characters specified in an array.Let us see an example to remove all trailing 1s −Example Live ...

Reference Parameters A reference parameter is a reference to a memory location of a variable. The reference parameters represent the same memory location as the actual parameters that are supplied to the method. When you pass parameters by reference, unlike value parameters, a new storage location is not created for these parameters. Pass by Value This is the default mechanism for passing parameters to a method. In this mechanism, when a method is called, a new storage location is created for each value parameter. The values of the actual parameters are copied into them. Hence, the changes made to the ... Read More

Method hiding is also called shadowing in C#. The method of the parent class is available to the child class without using the override keyword in shadowing. The child class has its own version of the same function. Define a behavior that is specific to the subclass type in overriding, you, which means a subclass can implement a parent class method based on its requirement. Hiding redefines the complete method, whereas overriding redefines only the implementation of the method. In Overriding, you can access the base class using the child class’ object overridden method.. Shadowing has cannot access the ... Read More

Read()The Read() reads the next characters from the standard input stream. If a key is pressed on the console, then it would close.int a = Console.Read() Console.WriteLine(a);ReadLine()It reads the next line of characters from the standard input stream.Example Live Demousing System; class Program {    static void Main() {       int x = 10;       Console.WriteLine(x);       Console.Write("Press any key to continue... ");       Console.ReadLine();    } }Output10 Press any key to continue...

Let us understand the difference between initialization and assignment of values. Declaring an array. int [] n // declaring Initialization Declaring an array does not initialize the array in the memory. When the array variable is initialized, you can assign values to the array. Array is a reference type, so you need to use the new keyword to create an instance of the array. int n= new int[10]; // initialization Let’s assign value. You can assign values to individual array elements, by using the index number − n[0] = 100; n[1] = 200 ... Read More

ConstConstant fields are the fields that cannot be modified. At the time of declaration, you need to assign a value to it.const int a = 5;ReadonlyA Read-only field is initialized at the time of declaration or you can also set it within the constructor.Let us see an example in which the read-only field is initialized inside the constructor −Exampleclass Calculate {    readonly int z;    public Demo( ) {       z = 20;    } }

C# has object and classes like Java. Objects are real-world entities and instance of a class. Access the members of the class using an object.To access the class members, you need to use the dot (.) operator after the object name. The dot operator links the name of an object with the name of a member, for example, Box Box1 = new Box();Above you can see Box1 is our object. We will use it to access the members.Box1.height = 3.0;You can also use it to call member functions.Box1.getVolume();The following is an example showing how objects and class work in C#.Example Live ...

Divide by zero is the System.DivideByZeroException, which is a class that handles errors generated from dividing a dividend with zero.Let us see an example.Example Live Demousing System; namespace ErrorHandlingApplication {    class DivNumbers {       int result;       DivNumbers() {          result = 0;       }       public void division(int num1, int num2) {          try {             result = num1 / num2;          } catch (DivideByZeroException e) {             Console.WriteLine("Exception caught: ...

Some of the popular methods of a Thread class is start, sleep, jon, and abort. Let us see the complete list of methods − Sr.No. Method & Description 1 public void Abort() Raises a ThreadAbortException in the thread on which it is invoked, to begin the process of terminating the thread. Calling this method usually terminates the thread. 2 public static LocalDataStoreSlot AllocateDataSlot() Allocates an unnamed data slot on all the threads. For better performance, use fields that are marked with the ThreadStaticAttribute attribute instead. 3 public static LocalDataStoreSlot AllocateNamedDataSlot(string name) Allocates ... Read More

Read()The Read() reads the next characters from the standard input stream. If a key is pressed on the console, then it would close.int az = Console.Read() Console.WriteLine(z);ReadKey()It reads only a single charactare from the standard input stream.ReadLine()Reads the next line of characters from the standard input stream.Example Live Demousing System; class Program {    static void Main() {       int x = 10;       Console.WriteLine(x);       Console.Write("Press any key to continue... ");       Console.ReadLine();    } }Output10 Press any key to continue...
