Splitting a string into an array?

Hey, all. Having a bit of trouble splitting this string into an array and then displaying it in a message box. Here's my code:

Code:

---

                Dim myString As String = "abcdefg"
                Dim myArray As Array = myString.Split("")
                MsgBox(myArray)

---

That should, if I'm not mistaken (which I am, because it's not working ;)) split up the string "myString" and put each character in its own entry of myArray, and then display the entire array in a message box, but that isn't happening. The error I'm getting when I do this is as follows:

Quote:

Argument 'Prompt' cannot be converted to type 'String'.

---

Also - do you reference a specific entry of an array via the opening and closing brackets like this?: [STRINGNUMBER]


Thanks!

Your trouble is that you can't display an array in a msgbox like that. The prompt argument of the Msgbox function takes a string so you'd have to show a string or join the array elements back together.

Msgbox(myArray(0))

myString.Split("") doesn't split the text on each character when i try. Upper bound of the array is 0.

I've found that what you said is correct. So the question is, how do you put each character of the string in to its own element in the array?

Dim s as string = "ABCDE"
Dim c as Char
dim arr() as string
dim i as short=0

'redim your array to the length of the string

For Each c In s
arr(i) = c
i+=1
Next

Actually a string is just an array of char and you can access that array with the Char property of the string variable.

VB Code:

msgbox(myString.Char(2))

Yes. I have to split the string into an array and then monkey with it a bit.

Thanks for your help guys. Got what I needed :)


Peace!

Using regular expressions is much easier..

Code:

---

using System.Text.RegularExpressions;

string splitThis = "stuff to split";
MatchCollection words = Regex.Matches(splitThis, @"\w+");

foreach(Match m in words) {
    Console.WriteLine(m.ToString());
}

---

Take a look at the System.Text.RegularExpressions namespace in your object browser and play around. You can find some tutorials on the web (or probably just do a search in the MSDN docs) on how to make string patterns for the regular expressions.

Alright, will do. Thankyou for your help. :)
