Question

I need to pass a variable by name like this

Dim html_news = "...the news ..."
Dim var = "news"
Dim a = "html_" & var
' content of that variable

How can I do that in VB.NET ?

Answer 1

vb.net doesn’t really lend itself to what you need to do – you could have done that sort of thing in scripting languages like classic asp and JavaScript. Although it might not have been the ‘right’ way to do it – the use of the ‘eval’ function is frowned on in Javscript as it’s a security risk. I think the code below will do what you need in a way that’s more in keeping with the way that vb.net works –

Dim d As New Dictionary(Of String, String)()
Dim html_news = "...the news ..."
d.Add("html_news","...the news ...")
Dim var = "news"
Dim a = d("html_" & var)
