The parameters are used to pass and receive data from a method. Let us first see the syntax −Access Specifier − This determines the visibility of a variable or a method from another class.Return type − A method may return a value. The return type is the data type of the value the method returns. If the method is not returning any values, then the return type is void.Method name − Method name is a unique identifier and it is case sensitive. It cannot be same as any other identifier declared in the class.Parameter list − Enclosed between parentheses, the ... Read More

To reverse the order of the elements in the entire List, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(String[] args) {       List list = new List();       list.Add("One");       list.Add("Two");       list.Add("Three");       list.Add("Four");       list.Add("Five");       list.Add("Six");       list.Add("Seven");       list.Add("Eight");       Console.WriteLine("Enumerator iterates through the list elements...");       List.Enumerator demoEnum = list.GetEnumerator();       while (demoEnum.MoveNext()) {          string res ...

Byte Struct in C# represents an 8-bit unsigned integer. Following are the fields −Sr.noField & Description1MaxValueRepresents the largest possible value of a Byte. This field is constant.2MinValueRepresents the smallest possible value of a Byte. This field is constant.Following are some of the methods −Sr.noField & Description1CompareTo(Byte)Compares this instance to a specified 8-bit unsigned integer and returns an indication of their relative values.2CompareTo(Object)Compares this instance to a specified object and returns an indication of their relative values.3Equals(Byte)Returns a value indicating whether this instance and a specified Byte object represent the same value.4Equals(Object)Returns a value indicating whether this instance is equal to ...

The finally keyword is used as a block to execute a given set of statements, whether an exception is thrown or not thrown. For example, if you open a file, it must be closed whether an exception is raised or not.SyntaxFollowing is the syntax −try {    // statements causing exception } catch( ExceptionName e1 ) {    // error handling code } catch( ExceptionName e2 ) {    // error handling code } catch( ExceptionName eN ) {    // error handling code } finally {    // statements to be executed }ExampleLet us see an example to implement ...
