Interface IHostingEnvironment

Namespace: Umbraco.Cms.Core.Hosting

Assembly: Umbraco.Core.dll

Syntax

public interface IHostingEnvironment

Properties

ApplicationId

The unique application ID for this Umbraco website.

Declaration

string ApplicationId { get; }

Property Value

Type	Description
System.String

Remarks

The returned value will be the same consistent value for an Umbraco website on a specific server and will the same between restarts of that Umbraco website/application on that specific server.

The value of this does not distinguish between unique workers/servers for this Umbraco application. Usage of this must take into account that the same ApplicationId may be returned for the same Umbraco website hosted on different servers.
Similarly the usage of this must take into account that a different ApplicationId may be returned for the same Umbraco website hosted on different servers.

This returns a hash of the value of IApplicationDiscriminator.Discriminator (which is most likely just the value of unless an alternative implementation of IApplicationDiscriminator has been registered).
However during ConfigureServices a temporary instance of IHostingEnvironment is constructed which guarantees that this will be the hash of , so the value may differ depend on when the property is used.

If you require this value during ConfigureServices it is probably a code smell.

ApplicationMainUrl

Gets the main application url.

Declaration

Uri ApplicationMainUrl { get; }

Property Value

Type	Description
Uri

ApplicationPhysicalPath

Will return the physical path to the root of the application

Declaration

string ApplicationPhysicalPath { get; }

Property Value

Type	Description
System.String

ApplicationVirtualPath

The web application's hosted path

Declaration

string ApplicationVirtualPath { get; }

Property Value

Type	Description
System.String

Remarks

In most cases this will return "/" but if the site is hosted in a virtual directory then this will return the virtual directory's path such as "/mysite". This value must begin with a "/" and cannot end with "/".

IsDebugMode

Declaration

bool IsDebugMode { get; }

Property Value

Type	Description
System.Boolean

IsHosted

Gets a value indicating whether Umbraco is hosted.

Declaration

bool IsHosted { get; }

Property Value

Type	Description
System.Boolean

LocalTempPath

Declaration

string LocalTempPath { get; }

Property Value

Type	Description
System.String

SiteName

Declaration

string SiteName { get; }

Property Value

Type	Description
System.String

Methods

EnsureApplicationMainUrl(Nullable<Uri>)

Ensures that the application know its main Url.

Declaration

void EnsureApplicationMainUrl(Uri? currentApplicationUrl)

Parameters

Type	Name	Description
System.Nullable<Uri>	currentApplicationUrl

MapPathContentRoot(String)

Maps a virtual path to a physical path to the application's root (not always equal to the web root)

Declaration

string MapPathContentRoot(string path)

Parameters

Type	Name	Description
System.String	path

Returns

Type	Description
System.String

Remarks

Depending on the runtime 'web root', this result can vary. For example in Net Framework the web root and the content root are the same, however in netcore the web root is /www therefore this will Map to a physical path within www.

MapPathWebRoot(String)

Maps a virtual path to a physical path to the application's web root

Declaration

string MapPathWebRoot(string path)

Parameters

Type	Name	Description
System.String	path

Returns

Type	Description
System.String

Remarks

Depending on the runtime 'web root', this result can vary. For example in Net Framework the web root and the content root are the same, however in netcore the web root is /www therefore this will Map to a physical path within www.

ToAbsolute(String)

Converts a virtual path to an absolute URL path based on the application's web root

Declaration

string ToAbsolute(string virtualPath)

Parameters

Type	Name	Description
System.String	virtualPath	The virtual path. Must start with either ~/ or / else an exception is thrown.

Returns

Type	Description
System.String

Remarks

This maps the virtual path syntax to the web root. For example when hosting in a virtual directory called "site" and the value "~/pages/test" is passed in, it will map to "/site/pages/test" where "/site" is the value of ApplicationVirtualPath.
