Primarily the MID and dictionary usage are unfamiliar to me. Can this be completely converted to C#?

Answer 1

StringDictionary is just another collection class so no problem. Mid could still be used as Microsoft.VisualBasic.Mid() if you're willing to import the Visual Basic library to your C# app (nothing bad about that) or it could be rewritten fairly easily.

Edit: Actually, the VB.Net code just seems to use the Mid in the same way as you can use String.Substring so no need to use the Visual Basic library even. (I was thinking of Mid in VB6 that could be either a function or a statement, the function is similar to String.Substring but there's no real easy way to replicate it if it's the statement one but either way, doesn't matter for this code).

Answer 2

Have you tried using the Telerik Converter ? I ran your stuff through there and didn't get any errors.

Answer 4

Yes. Use one of the converter tools mentioned here; only run through the code though, and not the markup parts of it.
