Suppress warning from a single line

[Kim Hellan]

I want to suppress the following warning when compiling.
warning CS0169: The private field 'myvar' is never used

In C++ you would do something like (not sure of the syntax):
#pragma nowarn:0169
string myvar;
#pragma warn:0169

Is this really still not possible in C#?
I know you can set the /nowarn:0169 option in you project, but I do not want
to disable it for everything in the project..
I just want to disable it from that one line until 'myvar' gets implemented.

Kim,

You can not do this in C#, you will have to disable the warning.

Of course, the warnings are there for a reason, and the fix is simple
for your particular warning, so it's probably better that you code the
variable declaration the right way.

Hope this helps.

Sure it is. The syntax is far simpler as well (actually, you can do the same thing in C++)
just change
string myvar;
to
// string myvar;

There...problem solved.

OK, I am joking around a bit, but really, why not just comment it out until you are ready to use it?

No, really, I am sure you will have thought of commenting it out considering the depth of solution
you have persued.
What is wrong with the comment?

Surer Kim. Use:

#pragma warning disable
#pragma warning restore

You can also use this directive with a comma-delimited list of warning
numbers. Example:

#pragema warning disable 0169

Note that (as far as I can tell) this is for C# 2.0 only. It certainly
doesn't seem to work with the 1.1 compiler. (Interestingly enough, I
couldn't find it in my printed copy of the C# 2.0 spec I was looking at
earlier...)

Darn, Jon! Most of the time I look in the correct version of the MSDN
library, but the one I use the most is the 2.0 version. I can assure you,
though, at least in .Net 2.0, it's there!

Yup - I checked that it would work with 2.0 (at least the beta 2). I'm
still surprised I couldn't find it in the language spec though. Must
have a closer look tomorrow...
