Reflection - Dynamically invoking property

What should be the obj in this case?

Ennis Ray Lynch Jr

obj is the instance of the object you are using. The one with your attributes and properties. Really, if you check the MSDN on the topic it is relatively thorough.

Got it, Thanks all for your help

Ok, but that doesn't explain how property is blue and null is not

Oh, I just looked at my post. I had no idea what you are talking about. Ask the site admins if you want to know what crazy stuff happens not me :)

Ok, well plug in the current instance of Form1... If you're running this code inside the form, it'd just be "this"... If you're running it elsewhere, then, well, I assume you have a reference to the form, so pop that in there.

And I even added a (very) brief explanation... Ha! I win the prize! :-D Wait... There's no prize? :((

That's what you get to see in a pre-tag without specifying the language;

Control control = (Control)property.GetValue(obj, null);

This is with the language set to C#;

Control control = (Control)property.GetValue(obj, null);

Ok thanks :)

It must be guessing VB instead of C... If I remember right (Been a while), in VB, you define a property as:

Public Property Something
Get
Return _localVariable
End Get
Set
_localVariable = Value
End Set
End Property

So "Property" is blue... Dunno why it would guess that for your code line though... You figure the "null" would be a dead giveaway that it's C/C++/C#

You need to take some responsibility for the craziness too; a PRE or CODE tag accepts an optional LANG attrribute where you specify the language, and hence the applicable list of keywords. More information can be found here[^]. By default the language stuff is handled automatically when pasting in Q&A (based on code I provided here: PRE tags galore: LPCodeRecognizer[^]). So far Chris hasn't been willing or able to implement it also in the forums. There is a default, unfortunately it is C++ everywhere (and not C# as was documented somewhere), and independent of the actual forum. And then there are some bugs in the syntax colorizer, IIRC it is easily confused by quoted stuff. Conclusion: the best you can do is change <PRE> into <PRE lang="CS"> and hope for the best. :)

Please use <PRE> tags for code snippets, they preserve indentation, and improve readability.

There is no guessing in the forums, it is just a bad default IMO. See my reply here[^]. :)
