In C#, a property is a member that provide flexible mechanism to read, write or compute the value of a private field.
Or
Properties are fields. A field member can be accessed directly, but a property member is always accessed through accessor and modifier methods called get and set, respectively.
The following syntax is used for writing a property :
public <type> <Property Name> {
get {
return <var>;
}
set {
//validate the input, found in value
if( IsValid(value))
<var> = value;
}
}
Let’s take one example how to working with properties in C# programming language.
using System;
namespace ConsoleApp
{
class myClass
{
private bool _Gender;
private int _Age;
// Gender property.
public bool Gender
{
get
{
return _Gender;
}
set
{
_Gender = value;
}
}
// Age property
public int Age
{
get
{
return _Age;
}
set
{
_Age = value;
}
}
}
class TestmyClass
{
static void Main()
{
myClass cls = new myClass();
// set properties values
cls.Gender = true;
cls.Age = 25;
if (cls.Gender)
{
Console.WriteLine("The Gender is Male");
Console.WriteLine("Age is " + cls.Age.ToString());
}
}
}
}
The output of the above c# program…
myClass. Age and Gender.Age is an integer property, and Gender is a Boolean type property.get and set keywords are used to get and set property values.A read-only property is a property that has a get() accessor but does not have a set() accessor.
This means that you can retrieve the value of a variable but you can not assign a value to the variable.
using System;
namespace ConsoleApp
{
class PropertyHolder
{
private int _Age = 40;
public int Age
{
get
{
return _Age;
}
}
}
class PropertyTester
{
public static void Main(string[] args)
{
PropertyHolder propHold = new PropertyHolder();
Console.WriteLine("Your age is : " + propHold.Age);
}
}
}
The output of the above C# program…
