Call a property using a string

[Chad Miller]

I have a class with 50 properties sp01 .. sp50 is there a way to call a
property using a string?
ex. o.sp & "01"

You can, but be careful, the compiler won't complain if a name is missing:
see the CallByName statment and the topic "Reflection":
http://msdn.microsoft.com/library/en...natruntime.asp

especially sub topic "Dynamically Loading and Using Types"

Thanks, that worked great! It also taught me allot about the reflection
class.

You can accoplish this easily using reflection.

Imports System.Reflection

Public Function GetPropertyValueByName(ByVal num As String) As String
Dim t As Type = Me.GetType()
Dim pi As PropertyInfo = t.GetProperty("sp" & num)
Return CType(pi.GetValue(Me, Nothing), String)
End Function
