As you can see, the properties 

Count

 and 

Str

are set via object initializer expressions. The 

output is the same as that produced by the program in Chapter 8 and is shown here:

100 Testing

As explained in Chapter 8, the object initializer syntax is most useful when working 

with anonymous types generated by a LINQ expression. In most other cases, you will use 

the normal constructor syntax.

Property Restrictions

Properties have some important restrictions. First, because a property does not define a storage 

location, it cannot be passed as a 

ref

 or 

out

 parameter to a method. Second, you cannot 

overload a property. (You 

can

 have two different properties that both access the same variable, 

but this would be unusual.) Finally, a property should not alter the state of the underlying 

variable when the 

get

 accessor is called. Although this rule is not enforced by the compiler, 

violating it is semantically wrong. A 

get

 operation should be nonintrusive.
