Are all of these equal? Under what circumstances should I choose each over the others?
1.ToString()
2.CStr(var)
3.CType(var, String)
4.DirectCast(var, String)
EDIT: Suggestion from NOTMYSELF…
5.TryCast(var, String)
Those are all slightly different and generally have acceptable usage.
TOSTRING()is going to give you the string representation of an object, regardless of what type it is. Use this if var is not a string already.
CSTR(var)is the VB string, cast operator. I’m not a VB guy, so I would suggest avoiding it, but it’s not really going to hurt anything. I think it is basically the same as CType.
CTYPE(var, String)will convert the given type into a string, using any provided conversion operators.
DIRECTCAST(var, String)is used to up-cast an object into a string. If you know that an object variable is, in fact, a string, use this. This is the same as (string)var in C#.
TRYCAST(as mentioned by @NotMyself) is like DirectCast, but it will return Nothing if the variable can’t be converted into a string, rather than throwing an exception. This is the same as var as a string in C#. The TryCast page on MSDN has a good comparison, too.
