Format(Type, Object, String)

Converts the specified value of a specified enumerated type to its equivalent string representation according to the specified format.
GetHashCode()

Returns the hash code for the value of this instance.
GetName(Type, Object)

Retrieves the name of the constant in the specified enumeration that has the specified value.
GetName<TEnum>(TEnum)

Retrieves the name of the constant in the specified enumeration type that has the specified value.
GetNames(Type)

Retrieves an array of the names of the constants in a specified enumeration.
GetNames<TEnum>()

GetType()

Gets the Type of the current instance.

(Inherited from Object)
GetTypeCode()

Returns the type code of the underlying type of this enumeration member.
GetUnderlyingType(Type)

Returns the underlying type of the specified enumeration.
GetValues(Type)

Retrieves an array of the values of the constants in a specified enumeration.
GetValues<TEnum>()

Returns a boolean telling whether a given integral value, or its name as a string, exists in a specified enumeration.
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
Parse(Type, ReadOnlySpan<Char>, Boolean)

Converts the span of characters representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.
Parse(Type, String, Boolean)

Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-insensitive.
Parse(Type, String)

Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.
Parse<TEnum>(ReadOnlySpan<Char>, Boolean)

Converts the span of characters representation of the name or numeric value of one or more enumerated constants specified by TEnum to an equivalent enumerated object. A parameter specifies whether the operation is case-insensitive.
Parse<TEnum>(ReadOnlySpan<Char>)

Converts the span of characters representation of the name or numeric value of one or more enumerated constants specified by TEnum to an equivalent enumerated object.
Parse<TEnum>(String, Boolean)

Converts the string representation of the name or numeric value of one or more enumerated constants specified by TEnum to an equivalent enumerated object. A parameter specifies whether the operation is case-insensitive.
Parse<TEnum>(String)

Converts the string representation of the name or numeric value of one or more enumerated constants specified by TEnum to an equivalent enumerated object.
ToObject(Type, Byte)

Converts the specified 8-bit unsigned integer to an enumeration member.
ToObject(Type, Int16)

Converts the specified 16-bit signed integer to an enumeration member.
ToObject(Type, Int32)

Converts the specified 32-bit signed integer to an enumeration member.
ToObject(Type, Int64)

Converts the specified 64-bit signed integer to an enumeration member.
ToObject(Type, Object)

Converts the specified object with an integer value to an enumeration member.
ToObject(Type, SByte)

Converts the specified 8-bit signed integer value to an enumeration member.
ToObject(Type, UInt16)

Converts the specified 16-bit unsigned integer value to an enumeration member.
ToObject(Type, UInt32)

Converts the specified 32-bit unsigned integer value to an enumeration member.
ToObject(Type, UInt64)

Converts the specified 64-bit unsigned integer value to an enumeration member.
ToString()

Converts the value of this instance to its equivalent string representation.
ToString(IFormatProvider)
Obsolete.
Obsolete.

This method overload is obsolete; use ToString().
ToString(String, IFormatProvider)
Obsolete.
Obsolete.

This method overload is obsolete; use ToString(String).
ToString(String)

Converts the value of this instance to its equivalent string representation using the specified format.
TryFormat<TEnum>(TEnum, Span<Char>, Int32, ReadOnlySpan<Char>)

Tries to format the value of the enumerated type instance into the provided span of characters.
TryParse(Type, ReadOnlySpan<Char>, Boolean, Object)

Converts the span of characters representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object. A parameter specifies whether the operation is case-insensitive.
TryParse(Type, ReadOnlySpan<Char>, Object)

Converts the span of characters representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.
