From my understanding, this code:

Microsoft.VisualBasic.StrDup(3, "123")

should return 123123123. Instead it returns 111, as if it’s working with a wrong overload of StrDup (one that accepts char). If this is by-design, is there any built-in function that would do the same?

    According to MSDN, StrDup picks only the first character, regardless if you specify a Char or a String:

    Character – Required. Any valid Char, String, or Object expression.
    Only the first character of the expression will be used. If Character
    is of type Object, it must contain either a Char or a String value.

    The best way to do StrDup for strings is this:

    String.Join("", Enumerable.Repeat("123", 3))
