Chapter 3: Learning Just Enough C# and VB.NET: Types and Members 85
Since the CurrentBalance property returns the value of the accountBalance field,
the Console.WriteLine statement will print the value read from CurrentBalance to the
command line.
Many of the properties you’ll write will simply be wrappers around current object
state with no other logic, as in Listing 3-9.
Listing 3-9 Property that wraps object state with no logic
C#:
private string m_firstName;
public string FirstName
{
get
{
return m_firstName;
}
set
{
m_firstName = value;
}
}
VB:
Private m_firstName As String
Public Property FirstName() As String
Get
Return m_firstName
End Get
Set(ByVal value As String)
m_firstName = value
End Set
End Property
In Listing 3-9, you can see that m_firstName, commonly referred to as a backing
field, is a private variable and that the FirstName property only returns m_firstName
from the get accessor and assigns the value to m_firstName in the set accessor. Since
this is so common, you can save syntax by using an automatic property, as shown in
Listing 3-10.
