Assembly: mscorlib (in mscorlib.dll)

- s

Type:
System::String^
A string containing a number to convert.
| Exception | Condition |
|---|---|
| ArgumentNullException | s is null. |
| FormatException | s is not in the correct format. |
| OverflowException |
The s parameter contains a number of the form:
[ws][sign]digits[ws]
Elements in square brackets ([ and ]) are optional. The following table describes each element.
Element | Description |
|---|---|
ws | Optional white space. |
sign | An optional sign. |
digits | A sequence of digits ranging from 0 to 9. |
The s parameter is interpreted using the NumberStyles::Integer style. In addition to decimal digits, only leading and trailing spaces together with a leading sign are allowed. To explicitly define the style elements that can be present in s, use either the Int64::Parse(String^, NumberStyles) or the Int64::Parse(String^, NumberStyles, IFormatProvider^) method.
The s parameter is parsed using the formatting information in a NumberFormatInfo object that is initialized for the current system culture. To parse a string using the formatting information of some other culture, use the Int64::Parse(String^, NumberStyles, IFormatProvider^) method.
