   ByVal value As Object, _

[ C# ]

   object value,
   IFormatProvider provider

[ C++ ]
public: static __int64 ToInt64 ( 
   Object* value,
   IFormatProvider* provider
);

[ JScript ]
public static function ToInt64 (
   value : Object,
   provider : IFormatProvider
) : long;

value

An Object that implements the IConvertible interface.

provider

An IFormatProvider interface implementation that supplies culture-specific formatting information.

The 64-bit signed integer equivalent of value, or zero if value is a null reference ( Nothing in Visual Basic ).

The return value is the result of invoking the IConvertible.ToInt64 method of the underlying type of value.

provider enables the user to specify culture-specific conversion information about the contents of value. For example, if value is a String that represents a number, provider could supply culture-specific information about the notation used to represent that number.

The base types ignore provider; however, it is honored if value is a user-defined type that implements the IConvertible interface.
