Using a variable for a name

[Alex]

Given the following code:

Private Sub ButtonShowTheIn tValue_Click(By Val sender As System.Object, ByVal e
As System.EventArg s) Handles ButtonShowTheIn tValue.Click

MsgBox(String.F ormat("TheClass Instance.TheInt = {0:G}",
TheClassInstanc e.TheInt))

End Sub

The code above displays a simple message box that shows the value of the field
TheInt in the object TheClassInstanc e. If I rename the object or the field in
it's declaration I'll get an easily fixable error. However, there's the risk
of correcting the name of the variable, but leaving the string literal
unchanged. Is there somehow a way to replace the string literal
"TheClassInstan ce.TheInt" with a variable so that I would get a compilation
error if the field's name was to be changed in its declaration?

Re: Using a variable for a name

AFAIK, no, there is no direct way. Reflection allows you to discover types
fields at run time, but you need the name to identify an element. The only
workaround would be to attach an attribute to the field and use Reflection
at run time to locate the element whose attribute is that and then retrieve
the name.
