Convert label to double 1

[mancroft]

Hello

How do I convert a label to a double?

thedouble = thelabel

and

thedouble = CDbl(thelabel)

appear not to work.

Thank you.

Solved!

theDouble = Convert.ToDouble(theLabel.Text)

Convert is in the System namespace, so you generally always have access to it.

Chip, is there any difference between

theDouble = CDbl(theLabel.Text)

which I would have used, and your suggestion?

I believe that they end up being the same IL code (give or take). CDbl() is from the VB.NET language spec, while the Convert class is from the framework itself.

If you ever intend to learn one of the other .NET languages (J#, C#, COBOL.NET, etc), then it might be a good idea to learn more about the framework, and use the framework methods where possible.

If you're curious, you can write some code to illustrate each, and once it's compiled, run it through ildasm.exe (comes with the framework) or Reflector (

to view the IL code that gets produced by the compiler, and see which is more efficient.
