[SerializableAttribute] [ComVisibleAttribute(true)] public value class Int64 : IComparable, IFormattable, IConvertible, IComparable<long long>, IEquatable<long long>
/** @attribute SerializableAttribute() */ /** @attribute ComVisibleAttribute(true) */ public final class Int64 extends ValueType implements IComparable, IFormattable, IConvertible, IComparable<long>, IEquatable<long>
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, IFormattable, and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.
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.
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.
