NET Core 3.0 and later versions, no exception is thrown when s is out of range of the Double data type. NET Core 2.2 and earlier versions, if s is out of range of the Double data type, the TryParse(String, Double) method throws an OverflowException.
' The example displays the following output: String values = is outside the range of a Double.", _ It assumes that en-US is the current culture. The following example uses the TryParse(String, Double) method to convert the string representations of numeric values to Double values. True if s was converted successfully otherwise, false.
