Represents a globally unique identifier (GUID).

public value class Guid : IComparable, IComparable<Guid>, IEquatable<Guid>, IParsable<Guid>, ISpanFormattable, ISpanParsable<Guid>, IUtf8SpanFormattable

public readonly struct Guid : IComparable, IComparable<Guid>, IEquatable<Guid>, IParsable<Guid>, ISpanFormattable, ISpanParsable<Guid>, IUtf8SpanFormattable

type Guid = struct
    interface IFormattable
    interface IParsable<Guid>
    interface ISpanFormattable
    interface ISpanParsable<Guid>
    interface IUtf8SpanFormattable

Public Structure Guid
Implements IComparable, IComparable(Of Guid), IEquatable(Of Guid), IParsable(Of Guid), ISpanFormattable, ISpanParsable(Of Guid), IUtf8SpanFormattable

Remarks

A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated.

Constructors

Guid(Byte[])	Initializes a new instance of the Guid structure by using the specified array of bytes.
Guid(Int32, Int16, Int16, Byte, Byte, Byte, Byte, Byte, Byte, Byte, Byte)	Initializes a new instance of the Guid structure by using the specified integers and bytes.
Guid(Int32, Int16, Int16, Byte[])	Initializes a new instance of the Guid structure by using the specified integers and byte array.
Guid(ReadOnlySpan<Byte>, Boolean)
Guid(ReadOnlySpan<Byte>)	Initializes a new instance of the Guid structure by using the value represented by the specified read-only span of bytes.
Guid(String)	Initializes a new instance of the Guid structure by using the value represented by the specified string.
Guid(UInt32, UInt16, UInt16, Byte, Byte, Byte, Byte, Byte, Byte, Byte, Byte)	Initializes a new instance of the Guid structure by using the specified unsigned integers and bytes.

Fields

Empty

A read-only instance of the Guid structure whose value is all zeros.

Properties

AllBitsSet	Gets a Guid where all bits are set.
Variant	Gets the value of the variant field for the Guid.
Version	Gets the value of the version field for the Guid.

Methods

CompareTo(Guid)	Compares this instance to a specified Guid object and returns an indication of their relative values.
CompareTo(Object)	Compares this instance to a specified object and returns an indication of their relative values.
CreateVersion7()	Creates a new Guid according to RFC 9562, following the Version 7 format.
CreateVersion7(DateTimeOffset)	Creates a new Guid according to RFC 9562, following the Version 7 format.
Equals(Guid)	Returns a value indicating whether this instance and a specified Guid object represent the same value.
Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object.
GetHashCode()	Returns the hash code for this instance.
NewGuid()	Initializes a new instance of the Guid structure.
Parse(ReadOnlySpan<Char>, IFormatProvider)	Parses a span of characters into a value.
Parse(ReadOnlySpan<Char>)	Converts a read-only character span that represents a GUID to the equivalent Guid structure.
Parse(String, IFormatProvider)	Parses a string into a value.
Parse(String)	Converts the string representation of a GUID to the equivalent Guid structure.
ParseExact(ReadOnlySpan<Char>, ReadOnlySpan<Char>)	Converts the character span representation of a GUID to the equivalent Guid structure, provided that the string is in the specified format.
ParseExact(String, String)	Converts the string representation of a GUID to the equivalent Guid structure, provided that the string is in the specified format.
ToByteArray()	Returns a 16-element byte array that contains the value of this instance.
ToByteArray(Boolean)
ToString()	Returns a string representation of the value of this instance in registry format.
ToString(String, IFormatProvider)	Returns a string representation of the value of this instance of the Guid class, according to the provided format specifier and culture-specific format information.
ToString(String)	Returns a string representation of the value of this Guid instance, according to the provided format specifier.
TryFormat(Span<Byte>, Int32, ReadOnlySpan<Char>)
TryFormat(Span<Char>, Int32, ReadOnlySpan<Char>)	Tries to format the current GUID instance into the provided character span.
