Replace Function ASP.NET

[Naoise]

Try this in legacy ASP
ASP
Dim x
x=""
Response.write(TypeName(x))
x=Replace(x,";","")
Response.write(TypeName(x))

...and you will still have an empty string

Try it in ASP.NET
ASP.NET
Dim x As String
x = ""
Response.Write(TypeName(x))
x = Replace(x, ";", "")
Response.Write(TypeName(x))

...and you will see that it has gone from a String to type Nothing.

How is this?

That is because you are specifically setting x to Nothing in your ASP.NET example with this line:

x = Replace(x, ";", "")

Instead, that line should be replaced with:

x = x.Replace(";", "")

which will perform the Replace command actually on the String itself and therefore the type will remain the same.
