C# class field

In this chapter you will learn:

1. What is a class field
2. Syntax to create a new field
3. A class with fields
4. How to declare more than one fields

Description

A field is a variable that is a member of a class or struct.

Syntax

The field definition has the following syntax.

class className{/*from w  ww.  j av  a2 s . c om*/

  fieldAccessor  fieldType fieldName;

}

• fieldAccessor specifies the access,
• fieldType specifies the type of variable, and
• fieldName is the variable's name.

Example

A class with fields

class Person //from   w ww .  j a  v a 2 s . co m
{ 
   string name; 
   public int Age = 10; 
} 

Example 2

For the fields with the same type we can declare them together.

class Rectangle{
   int Width, Height;
}

They can share the same modifiers as well.

class Rectangle{
   public int Width, Height;

}
