Public Class UrlResolutionTagHelper
Inherits TagHelper

Inheritance: Object

TagHelper
UrlResolutionTagHelper

Derived: Microsoft.AspNetCore.Mvc.TagHelpers.ImageTagHelper

Microsoft.AspNetCore.Mvc.TagHelpers.LinkTagHelper

Microsoft.AspNetCore.Mvc.TagHelpers.ScriptTagHelper

Attributes: HtmlTargetElementAttribute

Remarks

Resolves URLs starting with '~/' (relative to the application's 'webroot' setting) that are not targeted by other ITagHelpers. Runs prior to other ITagHelpers to ensure application-relative URLs are resolved.

Constructors

UrlResolutionTagHelper(IUrlHelperFactory, HtmlEncoder)

Creates a new UrlResolutionTagHelper.

Properties

HtmlEncoder	The HtmlEncoder.
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.
UrlHelperFactory	The IUrlHelperFactory.
ViewContext	The ViewContext.

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`.
TryResolveUrl(String, IHtmlContent)	Tries to resolve the given `url` value relative to the application's 'webroot' setting.
TryResolveUrl(String, String)	Tries to resolve the given `url` value relative to the application's 'webroot' setting.
