Is there any kind of all encompassing "ToString" method with BrightScript? I have found a couple, but they seem to be specific to a cast such as Integer to String. My issue is I don't know what the type is for sure, so I keep getting "type mismatch" errors when trying to use one in a string compare.

Has anyone written a all catching ToString method or is there one built in that I am not seeing?

Thanks
Bud

You could check the variable first.
If type(variablename)="roInt" or type(variablename)="roInteger" Then

Basically any generic routine would be doing that already within it.

Thanks destruk!

I'm actually trying to do a conversion, not check what it is. I was hoping there was a built in method (like most other languages) that has a simple <value>.ToString().

But, maybe I'm thinking a bit too big, is there a way to determine what type a value is, and return that? So if I had "Foo", could I print what type of a value Foo is? At least this way I could walk a If Else tree and convert using one of the built in BrightScript methods.

Just a thought

Thanks
Bud

Ermm.. destruk just showed you how to do that...

How about something like this?

Function ToString(variable As Dynamic) As String
    If Type(variable) = "roInt" Or Type(variable) = "roInteger" Or Type(variable) = "roFloat" Or Type(variable) = "Float" Then
        Return Str(variable).Trim()
    Else If Type(variable) = "roBoolean" Or Type(variable) = "Boolean" Then
        If variable = True Then
            Return "True"
        End If
        Return "False"
    Else If Type(variable) = "roString" Or Type(variable) = "String" Then
        Return variable
    Else
        Return Type(variable)
    End If
End Function

Thanks endless,

That works really great! Exactly what I was looking for, thank you as always.

Best!

PS: Please be nice, I'm learning, I don't have your experience so things like this may fly over my head, I'm trying tho! 🙂
