Book I am reading says that Cstr() is best method for efficency and safety
however it doesnt compare that method of the .ToString() method.
Which is best.

IMHO (and this has been debated for quite some time now), you should view
all of the old "data-type" specific functions as legacy functions and no
longer use them. Instead, use the more object-oriented methods of a type.
CStr, CBool, CDbl, CInt, etc. would all be replaced with CType or .ToString
All date/time functions would be replaced with methods and properties of the
Date class
All string functions would be replaced with methods and properties of the
String class.
et all.

both points of view are valid, however i use the vb string methods as the
compiler makes optimzations that can improve performance over the native .Net
methods, also i find the vb methods read better.

for my clarification
..ToString() = native .Net methods
CStr() = vb String methods?
from my understanding in the book I am reading Cstr() etc is the perfered
way however it doesnt address .ToString()

The VB 6.0 way are not methods, they are functions. The .NET way are object
methods. The VB.NET compiler does NOT optimize the VB 6.0 functions to work
BETTER than the natvie .NET object methods.
To answer your question, ToString would be my suggestion, rather than
CStr(). ToString is a method of the Object Type, and since all classes
inherit from Object, all objects have this method. cheers

I don't think that's true at all. First off, CStr,CBool, Etc. are all just
easier-to-read specialized wrappers around CType..... which in and of itself
is a special "VB" construct. The true "non-VB" casting operator is
DirectCast(...) .
Contrary to what Scott M says you're SUPPOSED to use them. What's the point
of using VB if you're not going to use its special methods that make your
life easier? This is straight from the VB documentation:
"As a rule, you should use the Visual Basic type conversion functions in
preference to the .NET Framework methods such as ToString(), either on the
Convert class or on an individual type structure or class. The Visual Basic
functions are designed for optimal interaction with Visual Basic code, and
they also make your source code shorter and easier to read. In addition, the
..NET Framework conversion methods do not always produce the same results as
the Visual Basic functions, for example when converting Boolean to Integer.
For more information, see Troubleshooting Data Types."
In addition, although I'm a guy who always initializes strings and objects
as soon as possible rather than have them sit around until my algorithm uses
them- so I don't really care about the following- but, there's an advantage
to using VB's functions: they interpret "Nothing." You can't use the OO
methods on a string that is "Nothing" (s.ToUpper for instance won't work).

Why would you want to?
Oh, I get it, you're too lazy to check the data before performing an
operation it. Isn't checking your data a 100 level concept?
I'm guessing that On Error Resume Next is one of your friends too.

Wow, what happened to put you in this mood?
Checking if a variable actually contains data before doing a convert to
upper case is simply too much code. If you can avoid that it makes the code
a lot better readable.

You aren't serious, are you? If you can avoid that it makes the code a lot better readable.
You mean like the sentence above? I'm sure you meant "a lot more better
readablest".
