Does the *this* keyword refer to the class or the instance?
5  1859 
Hello, Does the *this* keyword refer to the class or the instance?
To the instance. From the C# Programmer's Reference v1.1:
"The this keyword refers to the current instance of the class. Static member
functions do not have a this pointer. The this keyword can be used to access
members from within constructors, instance methods, and instance accessors."
Hope this keeps the water cool.

Is it considered good practice to use the this keyword when calling a
method, even if it isn't necessary? The book I'm reading now (Murach's
C#) seems to do this a lot, and it seems unnecessary (yet somehow clearer).

In C#, it is not considered a good practice since most (naked) calls and
data access is assumed to be instance/class related. In 95% of the
cases, prefixing access with 'this' provides no benefit and hampers
refactoring.
In C++, it was generally more acceptable to prefix member access w/
this->, mostly because C++ is a hodge-podge of a language with both
classes and functional roots. Is it considered good practice to use the this keyword when calling a
