StringSegmentComparer Class


StringSegmentComparer Class	KGy SOFT Core Libraries Help

Represents a string comparison operation that uses specific case and culture-based or ordinal comparison rules allowing comparing strings by string, StringSegment and ReadOnlySpan<char> instances.
See the static properties for more details.

Properties

	Name	Description
	CurrentCulture	Gets a StringSegmentComparer object that performs a case-sensitive string comparison using the word comparison rules of the current culture. Depending on the targeted platform, the GetHashCode(StringSegment) method might allocate a new string. In .NET Core 3.0 and above none of the members of the returned StringSegmentComparer will allocate new strings.
	CurrentCultureIgnoreCase	Gets a StringSegmentComparer object that performs case-insensitive string comparisons using the word comparison rules of the current culture. Depending on the targeted platform, the GetHashCode(StringSegment) method might allocate a new string. In .NET Core 3.0 and above none of the members of the returned StringSegmentComparer will allocate new strings.
	InvariantCulture	Gets a StringSegmentComparer object that performs a case-sensitive string comparison using the word comparison rules of the invariant culture. Depending on the targeted platform, the GetHashCode(StringSegment) method might allocate a new string. In .NET Core 3.0 and above none of the members of the returned StringSegmentComparer will allocate new strings.
	InvariantCultureIgnoreCase	Gets a StringSegmentComparer object that performs a case-insensitive string comparison using the word comparison rules of the invariant culture. Depending on the targeted platform, the GetHashCode(StringSegment) method might allocate a new string. In .NET Core 3.0 and above none of the members of the returned StringSegmentComparer will allocate new strings.
	Ordinal	Gets a StringSegmentComparer object that performs a case-sensitive ordinal string comparison. The methods of the returned StringSegmentComparer instance can be called with string, StringSegment and ReadOnlySpan<char> parameter values, which will not allocate new strings on any platform.
	OrdinalIgnoreCase	Gets a StringSegmentComparer object that performs a case-insensitive ordinal string comparison. The methods of the returned StringSegmentComparer instance can be called with string, StringSegment and ReadOnlySpan<char> parameter values, which will not allocate new strings on any platform.
	OrdinalIgnoreCaseRandomized	Gets a StringSegmentComparer object that performs a case-insensitive ordinal string comparison. The returned comparer is functionally equivalent with OrdinalIgnoreCase but it ensures that the hash code of a specific string is stable only within the same process and AppDomain.
	OrdinalRandomized	Gets a StringSegmentComparer object that performs a case-sensitive ordinal string comparison. The returned comparer is functionally equivalent with Ordinal but it ensures that the hash code of a specific string is stable only within the same process and AppDomain.

Methods

	Name	Description
	Compare(Object, Object)	When overridden in a derived class, compares two objects and returns an indication of their relative sort order.
	Compare(ReadOnlySpanChar, ReadOnlySpanChar)	When overridden in a derived class, compares two ReadOnlySpan<char> instances and returns an indication of their relative sort order.
	Compare(String, String)	When overridden in a derived class, compares two string instances and returns an indication of their relative sort order.
	Compare(StringSegment, StringSegment)	When overridden in a derived class, compares two StringSegment instances and returns an indication of their relative sort order.
	Create	Creates a StringSegmentComparer object that compares strings according to the rules of a specified culture. Please note that the returned StringSegmentComparer may allocate new strings in some cases when targeting older frameworks. See the Remarks section for details.
	Equals(Object, Object)	When overridden in a derived class, indicates whether two objects are equal.
	Equals(ReadOnlySpanChar, ReadOnlySpanChar)	When overridden in a derived class, indicates whether two ReadOnlySpan<char> instances are equal.
	Equals(String, String)	When overridden in a derived class, indicates whether two string instances are equal.
	Equals(StringSegment, StringSegment)	When overridden in a derived class, indicates whether two StringSegment instances are equal.
	FromComparison	Gets a StringSegmentComparer instance based on the specified comparison. Please note that the returned StringSegmentComparer may allocate new strings in some cases. See the description of the properties for more details.
	GetHashCode(Object)	When overridden in a derived class, gets the hash code for the specified object.
	GetHashCode(ReadOnlySpanChar)	When overridden in a derived class, gets the hash code for the specified ReadOnlySpan<char>.
	GetHashCode(String)	When overridden in a derived class, gets the hash code for the specified string.
	GetHashCode(StringSegment)	When overridden in a derived class, gets the hash code for the specified StringSegment.
