Methods

	Name	Description
	CompareTo(Int64)	Compares this instance to a specified 64-bit signed integer and returns an indication of their relative values.
	CompareTo(Object)	Compares this instance to a specified object and returns an indication of their relative values.
	Equals(Int64)	Returns a value indicating whether this instance is equal to a specified Int64 value.
	Equals(Object)	Returns a value indicating whether this instance is equal to a specified object. (Overrides ValueType.Equals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetTypeCode	Returns the TypeCode for value type Int64.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Parse(String)	Converts the string representation of a number to its 64-bit signed integer equivalent.
	Parse(String, NumberStyles)	Converts the string representation of a number in a specified style to its 64-bit signed integer equivalent.
	Parse(String, IFormatProvider)	Converts the string representation of a number in a specified culture-specific format to its 64-bit signed integer equivalent.
	Parse(String, NumberStyles, IFormatProvider)	Converts the string representation of a number in a specified style and culture-specific format to its 64-bit signed integer equivalent.
	ToString()	Converts the numeric value of this instance to its equivalent string representation. (Overrides ValueType.ToString().)
	ToString(IFormatProvider)	Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information.
	ToString(String)	Converts the numeric value of this instance to its equivalent string representation, using the specified format.
	ToString(String, IFormatProvider)	Converts the numeric value of this instance to its equivalent string representation using the specified format and culture-specific format information.
	TryParse(String, Int64%)	Converts the string representation of a number to its 64-bit signed integer equivalent. A return value indicates whether the conversion succeeded or failed.
	TryParse(String, NumberStyles, IFormatProvider, Int64%)	Converts the string representation of a number in a specified style and culture-specific format to its 64-bit signed integer equivalent. A return value indicates whether the conversion succeeded or failed.

Remarks

The Int64 value type represents integers with values ranging from negative 9,223,372,036,854,775,808 through positive 9,223,372,036,854,775,807.

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.

This type implements interfaces IComparable, IComparable<T>, IFormattable, and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.

Thread Safety

All members of this type are thread safe. Members that appear to modify instance state actually return a new instance initialized with the new value. As with any other type, reading and writing to a shared variable that contains an instance of this type must be protected by a lock to guarantee thread safety.

Caution:
Assigning an instance of this type is not thread safe on all hardware platforms because the binary representation of that instance might be too large to assign in a single atomic operation.
