A Property Example
The following code shows an example of the declaration of a class called
C1
that contains a
property named
MyValue
.
Notice that the property itself does not have any storage. Instead, the accessors deter-
mine what should be done with data sent in, and what data should be sent out. In this
case, the property uses a field called
TheRealValue
for storage.
The set accessor takes its input parameter,
value
, and assigns that value to field
TheRealValue
.
The
get
accessor just returns the value of field
TheRealValue
.
Figure 6-9 illustrates the code.
class C1
{
private int TheRealValue; // Field: memory allocated
public int MyValue // Property: no memory allocated
{
set
{
TheRealValue = value;
}
get
{
return TheRealValue;
}
}
}

Property accessors often use fields for storage
