Converts a string to an Int64 value.
[Visual Basic] Overridable Public Function ToInt64() As Long [C#] public virtual long ToInt64(); [C++] public: virtual __int64 ToInt64(); [JScript] public function ToInt64() : long;
An Int64 with the value represented by value .
The ToInt64 implementation is the same as ToInt64. (In addition information, see Int64, Convert and Value.)
If the string is parsed as a decimal unless it is preceded by "0x", in which case it is parsed as a hexadecimal number. White space or trailing characters will cause a FormatException. The implementation is provided by Parse.
Note that if the beginning of the string value contains a properly formatted numerical value that will result in an overflow and, in addition, the end of the string is improperly formed, it cannot be determined whether an OverflowException or a FormatException will be thrown. This has been implemented this way for performance reasons.
