readonly significance?

[Jon Davis]

In C#, what is the difference between a property block that has a readonly
keyword and a get block, versus a property block that has only a get block?

Thanks,
Jon

The difference is that the one with just a get will compile ;-).

AFAIK readonly can only be applied to fields

the difference is that the one with readonly won't compile. readonly can
only be set on the field, but not the property.

Now if you're asking whats the difference between Foo and Bar in this example

class Quux
{
public int readonly Foo;
private int bar;
public int Bar
{
get{ return bar;}
}
}

the difference is Foo can only be set by the Quux constructor code (or a field initializer). Bar can only be read by clients of Quux, but the value it delivers can be changed by Quux any time it sees fit.
