Variable variables in C#

[midrange]

Is something like this possible in C#? (Maybe my googling skillls are rubbish)

$required_fields = array('name', 'email', 'message');
			
foreach($required_fields as $field){
				
[B]$$field = $field;[/B]
					
}

 

[mister]

String[] fields = new String[3] {"name", "email", "message"};
foreach (string s in fields)
{
MessageBox.Show("String array item: " + s);
}

That doesn't look to be creating dynamic variables though.

The PHP above creates the variables $name, $email and $message.

Why on earth would you want to create variables for which you dont know what their names are at compile time?

midrange, you can try a List<>.

List<string> lst_str_bob= new List<string>();
lst_str_bob.Add("bob1");
etc...

It's in Systems.Collections.Generic

Thanks dequadin and UnUnOctium.

Ancalagon, I find "variable variables" pretty handy in PHP.

Variable variables are yesterday's news. I use variable variable variables and I can't wait for variable variable variable variables to come out next year.

Pffft. All the cool kids are using inconsistent constants.

I raise you some factory building factory factories

I remember that... was AWESOME!

Just a question though, why not just use objects?

List<object> someList = new List<object> { "test", 1, 2.00, true };
foreach (object o in someList)
{
    Console.WriteLine(o.GetType());
}

A quick test revealed that it BUILDS correctly, but haven't tested the output yet...

 

[midrange]

List<object> someList = new List<object> { "test", 1, 2.00, true };
foreach (object o in someList)
{
Console.WriteLine(o.GetType());
}

That makes the most sense. I suppose the big difference is that PHP doesn't care about variable types.

.net framework 4 has expando objects which you create an object with your properties on the fly. maybe that can help you?

Might be useful in some instances, but I'll refrain from using it as a rule... Strongly-typing your properties is still a best-practice.

From what I've read (never used it) dynamic is cool.

Has loads of applications for JavaScript & COM.

JavaScript, yes, but for proper enterprise-scale apps where accurate (and strongly-typed) data is of utmost importance, I'm not too sure...

It might be useful in a CMS environment though - even emulating JS scripts on server-side.

Yo dawg, I heard you like variables...
