Syntax of Base keyword in C#
Following syntax is used to call a method of base Class from the derived Class:
namespace NS_hardwareManagerApp
{
//declare a base Class...///
class CL_aBaseClass
{
public void FN_Info()
{
}
}
//create a derived Class and inherit base Class...///
class CL_aDerivedClass : CL_aBaseClass
{
public void FN_Info()
{
//call base Class method in derived Class...///
base.FN_Info();
}
}
class CL_x
{
static void Main(string [] args)
{
Console.ReadLine();
}
}
}

Example of Base keyword in C#
Following example indicates how to call a base Class method from derived Class. Example is a console application which is created and test with Visual Studio 2008.

namespace NS_HRapplication
{
//declare a base Class...///
class CL_employees
{
public void FN_displaySalary()
{
Console.WriteLine("Salary is 1000 euro...");
}
}
//create a derived Class and inherit base Class...///
class CL_tehnicians : CL_employees
{
public void FN_displaySalary()
{
//we assume that managers are getting paid 1000 euro extra
than base employee salary...///
base.FN_displaySalary();
}
}
class CL_x
{
static void Main(string [] args)
{
//create a technician instance-object
.../// CL_tehnicians o_aTechnician = new CL_tehnicians();
//display salary...///
o_aTechnician.FN_displaySalary();
Console.ReadLine();
}
}
}
Application output:
