[Serializable] |
Int64 provides methods to compare instances of this type, convert the value of an instance to its string representation, and convert the string representation of a number to an instance of this type.
Assigning a 64-bit value on a 32-bit Intel computer is not an atomic operation; that is, the operation is not thread safe. This means that if two people simultaneously assign a value to a static Int64 field, the final value of the field cannot be predicted.For information about how format specification codes control the string representation of value types, see the conceptual topic at MSDN: formattingoverview.
This type implements interfaces IComparable, IFormattable, and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.| MaxValue | Represents the largest possible value of an Int64. This field is constant. |
| MinValue | Represents the smallest possible value of an Int64. This field is constant. |
| CompareTo | Compares this instance to a specified object and returns an indication of their relative values. |
| Equals | Overridden: Returns a value indicating whether this instance is equal to a specified object. |
| GetHashCode | Overridden: Returns the hash code for this instance. |
| GetType (inherited from System.Object) |
See base class member description: System.Object.GetType Derived from System.Object, the primary base class for all objects. |
| GetTypeCode | Returns the TypeCode for value type Int64. |
| Parse | Overloaded:Parse(string s) Converts the string representation of a number to its 64-bit signed integer equivalent. |
| Parse | Overloaded:Parse(string s, IFormatProvider provider) Converts the string representation of a number in a specified culture-specific format to its 64-bit signed integer equivalent. |
| Parse | Overloaded:Parse(string s, NumberStyles style) Converts the string representation of a number in a specified style to its 64-bit signed integer equivalent. |
| Parse | Overloaded:Parse(string s, NumberStyles style, IFormatProvider provider) Converts the string representation of a number in a specified style and culture-specific format to its 64-bit signed integer equivalent. |
| ToString | Overloaded:ToString()Overridden: Converts the numeric value of this instance to its equivalent string representation. |
| ToString | Overloaded:ToString(IFormatProvider provider) Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information. |
| ToString | Overloaded:ToString(string format) Converts the numeric value of this instance to its equivalent string representation, using the specified format. |
| ToString | Overloaded:ToString(string format, IFormatProvider provider) Converts the numeric value of this instance to its equivalent string representation using the specified format and culture-specific format information. |

value
| Return Value | Description |
|---|---|
| Less than zero | This instance is less than . |
| Zero | This instance is equal to . |
| Greater than zero | This instance is greater than value. -or- value is null. |
| Exception Type | Condition |
|---|---|
| ArgumentException | value is not an Int64 or null. |
The value parameter must be null or an instance of Int64, otherwise, an exception is thrown.

Items in square brackets ([ and ]) are optional, and other items are as follows.
The s parameter is parsed using the formatting information in a NumberFormatInfo initialized for the current system culture. For more information, see NumberFormatInfo.CurrentInfo.

Items in square brackets ([ and ]) are optional, and other items are as follows.
The provider parameter is an IFormatProvider that obtains a NumberFormatInfo object. The NumberFormatInfo provides culture-specific information about the format of s. If provider is null, the NumberFormatInfo for the current culture is used.

| OverflowException | s represents a number less than Int64.MinValue or greater than Int64.MaxValue. |
[ws][sign]digits[ws]
Items in square brackets ([ and ]) are optional, and other items are as follows.
The style parameter can be one or more NumberStyles enumerated constants combined using a bitwise OR operation (except NumberStyles.Any and NumberStyles.AllowDecimalPoint, which are invalid for the type returned by this method).
