UrlResolutionTagHelper

LinkTagHelper

Attributes

HtmlTargetElementAttribute

Constructors

LinkTagHelper(IWebHostEnvironment, TagHelperMemoryCacheProvider, IFileVersionProvider, HtmlEncoder, JavaScriptEncoder, IUrlHelperFactory)

Creates a new LinkTagHelper.

Properties

AppendVersion	Value indicating if file version should be appended to the href urls.
Cache	Gets the IMemoryCache used to store globbed urls.
FallbackHref	The URL of a CSS stylesheet to fallback to in the case the primary one fails.
FallbackHrefExclude	A comma separated list of globbed file patterns of CSS stylesheets to exclude from the fallback list, in the case the primary one fails. The glob patterns are assessed relative to the application's 'webroot' setting. Must be used in conjunction with FallbackHrefInclude.
FallbackHrefInclude	A comma separated list of globbed file patterns of CSS stylesheets to fallback to in the case the primary one fails. The glob patterns are assessed relative to the application's 'webroot' setting.
FallbackTestClass	The class name defined in the stylesheet to use for the fallback test. Must be used in conjunction with FallbackTestProperty and FallbackTestValue, and either FallbackHref or FallbackHrefInclude.
FallbackTestProperty	The CSS property name to use for the fallback test. Must be used in conjunction with FallbackTestClass and FallbackTestValue, and either FallbackHref or FallbackHrefInclude.
FallbackTestValue	The CSS property value to use for the fallback test. Must be used in conjunction with FallbackTestClass and FallbackTestProperty, and either FallbackHref or FallbackHrefInclude.
GlobbingUrlBuilder	Gets the GlobbingUrlBuilder used to populate included and excluded urls.
HostingEnvironment	Gets the IWebHostEnvironment for the application.
Href	Address of the linked resource.
HrefExclude	A comma separated list of globbed file patterns of CSS stylesheets to exclude from loading. The glob patterns are assessed relative to the application's 'webroot' setting. Must be used in conjunction with HrefInclude.
HrefInclude	A comma separated list of globbed file patterns of CSS stylesheets to load. The glob patterns are assessed relative to the application's 'webroot' setting.
HtmlEncoder	The HtmlEncoder. (Inherited from UrlResolutionTagHelper)
JavaScriptEncoder	Gets the JavaScriptEncoder used to encode fallback information.
Order	When a set of ITagHelpers are executed, their Init(TagHelperContext)'s are first invoked in the specified Order; then their ProcessAsync(TagHelperContext, TagHelperOutput)'s are invoked in the specified Order. Lower values are executed first.
SuppressFallbackIntegrity	Boolean value that determines if an integrity hash will be compared with FallbackHref value.
UrlHelperFactory	The IUrlHelperFactory. (Inherited from UrlResolutionTagHelper)
ViewContext	The ViewContext. (Inherited from UrlResolutionTagHelper)

Methods

Init(TagHelperContext)	Initializes the ITagHelper with the given context. Additions to Items should be done within this method to ensure they're added prior to executing the children. (Inherited from TagHelper)
Process(TagHelperContext, TagHelperOutput)	Synchronously executes the TagHelper with the given context and output.
ProcessAsync(TagHelperContext, TagHelperOutput)	Asynchronously executes the TagHelper with the given context and output. (Inherited from TagHelper)
ProcessUrlAttribute(String, TagHelperOutput)	Resolves and updates URL values starting with '~/' (relative to the application's 'webroot' setting) for output's Attributes whose Name is attributeName. (Inherited from UrlResolutionTagHelper)
TryResolveUrl(String, IHtmlContent)	Tries to resolve the given url value relative to the application's 'webroot' setting. (Inherited from UrlResolutionTagHelper)
TryResolveUrl(String, String)	Tries to resolve the given url value relative to the application's 'webroot' setting. (Inherited from UrlResolutionTagHelper)
