The Int64 type exposes the following members.

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

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.

.NET Framework

Supported in: 4, 3.5, 3.0, 2.0, 1.1, 1.0

.NET Framework Client Profile

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.

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 note 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.
