Convert currency to double

I have a value $17.50 as a string

how would i convert it to a double 17.50?

Assuming that your computers default currency is $ then this would work:

VB Code:

Dim str As String = "$17.50"
 
Dim dbl As Double = Double.Parse(str, Globalization.NumberStyles.Currency)
MsgBox(Format(dbl, "0.00"))

thank you
