Use Regular Expression to count occurrence of

I need to count the number of:

Alpha
Numeric
Other (non alpha-numeric, like symbols)
Upper Alpha
Lower Alpha

in a string.

Can Regular Expression be used of this purpose? It's okay if they're in separate function, but I need to somehow get the counts of each of the above. Any help would be appreciated.

try this:

vb Code:

Dim testStr As String = "Can Regular Expression be used of this purpose? It's okay if they're in separate function, but I need to somehow get the counts of each of the above. Any help would be appreciated. 0123456789"
MsgBox(New Regex("[A-Za-z]").Matches(testStr).Count.ToString) 'Alpha
MsgBox(New Regex("\d").Matches(testStr).Count.ToString) 'Numeric
MsgBox(New Regex("[^A-Za-z\d]").Matches(testStr).Count.ToString) 'Other
MsgBox(New Regex("[A-Z]").Matches(testStr).Count.ToString) 'Upper Alpha
MsgBox(New Regex("[a-z]").Matches(testStr).Count.ToString) 'Lower Alpha
