◆ ToUInt64() [16/19]

static ulong System.Convert.ToUInt64 ( string value )

static

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

Parameters

value A string that contains the number to convert.

Returns: A 64-bit signed integer that is equivalent to the number in value , or 0 (zero) if value is null.

Exceptions

T:System.FormatException	value does not consist of an optional sign followed by a sequence of digits (0 through 9).
T:System.OverflowException	value represents a number that is less than F:System.UInt64.MinValue or greater than F:System.UInt64.MaxValue.

static ulong System.Convert.ToUInt64	(	string	value,
		IFormatProvider	provider
	)

static

Parameters

value	A string that contains the number to convert.
provider	An object that supplies culture-specific formatting information.

Returns: A 64-bit unsigned integer that is equivalent to the number in value , or 0 (zero) if value is null.

Exceptions

T:System.FormatException	value does not consist of an optional sign followed by a sequence of digits (0 through 9).

◆ ToUInt64() [19/19]

static ulong System.Convert.ToUInt64	(	string	value,
		int	fromBase
	)

static

Converts the string representation of a number in a specified base to an equivalent 64-bit unsigned integer.

Parameters

value	A string that contains the number to convert.
fromBase	The base of the number in value , which must be 2, 8, 10, or 16.

Returns: A 64-bit unsigned integer that is equivalent to the number in value , or 0 (zero) if value is null.

Exceptions

T:System.ArgumentException	fromBase is not 2, 8, 10, or 16. -or- value , which represents a non-base 10 unsigned number, is prefixed with a negative sign.
T:System.ArgumentOutOfRangeException	value is F:System.String.Empty.
T:System.FormatException	value contains a character that is not a valid digit in the base specified by fromBase . The exception message indicates that there are no digits to convert if the first character in value is invalid; otherwise, the message indicates that value contains invalid trailing characters.
T:System.OverflowException	value , which represents a non-base 10 unsigned number, is prefixed with a negative sign.-or- value represents a number that is less than F:System.UInt64.MinValue or greater than F:System.UInt64.MaxValue.
