Simple get initials from string - Visual Basic

Question

Simple beginner exercise:

There's an input box where you put in your name seperated by spaces, then get the first letter from the first and last name and out put it to a label

I.e (Joe Bob) = JB

---

I know this could be done with an array, but the exercise is more to using string functions like substring, IndexOf, Remove, Replace etc...

Answer 1

There is the handy string method Split which splits a string at whitespaces by default, if you don't specify another delimiter.

Dim words As String() = TextBox1.Text.Split()
Dim initials As String = ""
For Each word As String In words
    initials &= word(0)
Next

Note: Strings can be indexed as if they were Char arrays. word(0) is the first character of word.

initials &= word(0)

is shorthand for

initials = initials & word(0)
