What is the C# equivelant of the following VB:
CType(controlTe mplate, TextBox).Text = ""
I'm basically trying to use a more general object as an argument in one
of my functions and then change the behavior within the function based
on its type.

David,
You would do this:
// Cast to a textbox and set the text property.
((TextBox) controlTemplate ).Text = string.Empty;
Hope this helps.

Hi David,
Use:
((TextBox)contr olTemplate).Tex t = ""

The equivelent is the cast operator
((TextBox)contr olTemplate).Tex t = "";

In addition to the short form given by the others, this method is a bit
safer:
TextBox tb = controlTemplate as TextBox;
if (tb != null)
tb.Text = "";

I agree,
Casting using "As" will return null if cast fails instead of an
invalidcastexce ption.

Why is that good though? If I've got something which *should* be a
TextBox, why is it good to mask the fact that my assumption is wrong?
There are times when it's better to use "as" - namely if your code
really doesn't know whether the cast should work or not - and there are
times when it's better to use a cast.

This question has probably been asked a million time, but here it comes
again. I want to learn the difference between the three type cast operators:
static_cast, reinterpret_cast, dynamic_cast. A good way to do this is by
example. So I will give an example and please tell me what you think:
I have a base
class A
with a virtual destructor, and a
class B
that is it inherits publicly from A and defines som extra stuff.

Hello,
I saw on a couple of recent posts people saying that casting the return
value of malloc is bad, like:
d=(double *) malloc(50*sizeof(double));
why is this bad? I had always thought (perhaps mistakenly) that the
purpose of a void pointer was to cast into a legitimate date type. Is
this wrong? Why, and what is considered to be correct form?

Hi everyone,
A basic one here, I think. I haven't found the pattern yet, but
sometimes when I cast a variable to another type using the "C" style cast
operator the compiler refuses to play along. It says it's an invalid cast.
However, if I use the Convert.ToInt32() method (for example) things will
work. At least, that's how it appears to me.
Could someone explain when to use old-style parenthesized casts vs. the
Convert() methods?

Hi ,
I was going through peter van der linden's book Expert C programming,
in this book there is a section named "How and why to cast"
the author then says as follows
(float) 3 - it's a type conversion and the actual bits change.
if you say (float) 3.0 it is a type disambiguation,and the compiler
can plant the correct bits in the first place.some people say that

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
