StringWithQualityHeaderValueComparer Class

Implementation of System.Collections.Generic.IComparer`1 that can compare content negotiation header fields based on their quality values (a.k.a q-values). This applies to values used in accept-charset, accept-encoding, accept-language and related header fields with similar syntax rules. See Microsoft.Net.Http.Headers.MediaTypeHeaderValueComparer for a comparer for media type q-values.

Syntax

public class StringWithQualityHeaderValueComparer : IComparer<StringWithQualityHeaderValue>
class Microsoft.Net.Http.Headers.StringWithQualityHeaderValueComparer

Methods

Compare(Microsoft.Net.Http.Headers.StringWithQualityHeaderValue, Microsoft.Net.Http.Headers.StringWithQualityHeaderValue)

Compares two Microsoft.Net.Http.Headers.StringWithQualityHeaderValue based on their quality value (a.k.a their “q-value”). Values with identical q-values are considered equal (i.e the result is 0) with the exception of wild-card values (i.e. a value of “*”) which are considered less than non-wild-card values. This allows to sort a sequence of Microsoft.Net.Http.Headers.StringWithQualityHeaderValue following their q-values ending up with any wild-cards at the end.

Arguments:
Return type:

System.Int32
Returns:

The result of the comparison.
