Syntax

[CLSCompliant(false)]
public struct UInt64

Fields

MaxValue

Represents the largest possible value of UInt64. This field is constant.

Declaration

public const ulong MaxValue = 18446744073709551615UL

Field Value

Type	Description
UInt64

Remarks

The value of this constant is 18,446,744,073,709,551,615; that is, hexadecimal 0xFFFFFFFFFFFFFFFF.

MinValue

Represents the smallest possible value of UInt64. This field is constant.

Declaration

public const ulong MinValue = 0UL

Field Value

Type	Description
UInt64

Remarks

The value of this constant is 0.

Methods

Parse(String)

Converts the string representation of a number to its 64-bit unsigned integer equivalent.

Declaration

[CLSCompliant(false)]
public static ulong Parse(string s)

Parameters

Type	Name	Description
String	s	A string that represents the number to convert.

Returns

Type	Description
UInt64	A 64-bit unsigned integer equivalent to the number contained in s.

Exceptions

Type	Condition
ArgumentNullException	s is null.

ToString()

Converts the numeric value of this instance to its equivalent string representation.

Declaration

public override string ToString()

Returns

Type	Description
String	The string representation of the value of this instance, consisting of a sequence of digits ranging from 0 to 9, without a sign or leading zeroes.

Overrides

Object.ToString()

ToString(String)

Converts the numeric value of this instance to its equivalent string representation using the specified format.

Declaration

public string ToString(string format)

Parameters

Type	Name	Description
String	format	A numeric format string.

Returns

Type	Description
String	The string representation of the value of this instance as specified by format.

TryParse(String, out UInt64)

Converts the string representation of a number to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded.

Declaration

public static bool TryParse(string s, out ulong result)

Parameters

Type	Name	Description
String	s	Converts the string representation of a number to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded.
UInt64	result	When this method returns, contains the 64-bit unsigned integer value equivalent of the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null or Empty, is not of the correct format, or represents a number less than MinValue or greater than MaxValue. This parameter is passed uninitialized; any value originally supplied in result will be overwritten.

Returns

Type	Description
Boolean	true if s was converted successfully; otherwise, false.

Remarks

The TryParse(String, out UInt64) method is like the Parse(String) method, except the TryParse(String, out UInt64) method does not throw an exception if the conversion fails. It eliminates the need to use exception handling to test for a FormatException in the event that s is invalid and cannot be successfully parsed.
