Remarks

The UInt64 value type represents unsigned integers with values ranging from 0 to 18,446,744,073,709,551,615.

Important

The UInt64 type is not CLS-compliant. The CLS-compliant alternative type is Decimal. Int64 can be used instead to replace a UInt64 value that ranges from zero to MaxValue. For more information about CLS compliance, see Language Independence and Language-Independent Components.

UInt64 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.

Fields

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

Methods

CompareTo(Object)	Compares this instance to a specified object and returns an indication of their relative values.
CompareTo(UInt64)	Compares this instance to a specified 64-bit unsigned integer and returns an indication of their relative values.
Equals(Object)	Returns a value indicating whether this instance is equal to a specified object.
Equals(UInt64)	Returns a value indicating whether this instance is equal to a specified UInt64 value.
GetHashCode()	Returns the hash code for this instance.
GetTypeCode()	Returns the TypeCode for value type UInt64.
Parse(ReadOnlySpan<Char>, NumberStyles, IFormatProvider)	Converts the span representation of a number in a specified style and culture-specific format to its 64-bit unsigned integer equivalent.
Parse(String)	Converts the string representation of a number to its 64-bit unsigned integer equivalent.
Parse(String, IFormatProvider)	Converts the string representation of a number in a specified culture-specific format to its 64-bit unsigned integer equivalent.
Parse(String, NumberStyles)	Converts the string representation of a number in a specified style to its 64-bit unsigned 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 unsigned integer equivalent.
ToString()	Converts the numeric value of this instance to its equivalent string representation.
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.
TryFormat(Span<Char>, Int32, ReadOnlySpan<Char>, IFormatProvider)	Tries to format the value of the current unsigned long number instance into the provided span of characters.
TryParse(ReadOnlySpan<Char>, NumberStyles, IFormatProvider, UInt64)	Tries to convert the span representation of a number in a specified style and culture-specific format to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded or failed.
TryParse(ReadOnlySpan<Char>, UInt64)	Tries to convert the span representation of a number to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded or failed.
TryParse(String, NumberStyles, IFormatProvider, UInt64)	Tries to convert the string representation of a number in a specified style and culture-specific format to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded or failed.
TryParse(String, UInt64)	Tries to convert the string representation of a number to its 64-bit unsigned integer equivalent. A return value indicates whether the conversion succeeded or failed.

Explicit Interface Implementations

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.
