String is already a collection of characters, so you can say:

[SIZE=2][COLOR=#0000ff]For [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Each[/COLOR][/SIZE][SIZE=2] c [/SIZE][SIZE=2][COLOR=#0000ff]As [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Char [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]In [/COLOR][/SIZE]theString
 
[COLOR=#0000ff]Next [/COLOR]

[SIZE=2][COLOR=#0000ff]For[/COLOR][/SIZE][SIZE=2] i [/SIZE][SIZE=2][COLOR=#0000ff]As [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Integer[/COLOR][/SIZE][SIZE=2] = 0 [/SIZE][SIZE=2][COLOR=#0000ff]To[/COLOR][/SIZE][SIZE=2] theString.Length - 1[/SIZE]
[SIZE=2][COLOR=#0000ff]  Dim[/COLOR][/SIZE][SIZE=2] c [/SIZE][SIZE=2][COLOR=#0000ff]As [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Char[/COLOR][/SIZE][SIZE=2] = theString(i)[/SIZE]
[SIZE=2][COLOR=#0000ff]Next[/COLOR][/SIZE]

[SIZE=2][COLOR=#0000ff]Dim[/COLOR][/SIZE][SIZE=2] chars() [/SIZE][SIZE=2][COLOR=#0000ff]As [/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Char[/COLOR][/SIZE][SIZE=2] = theString.ToCharArray[/SIZE]

If you want to search for position of a character use the String.IndexOf method
