A collection of related resources, typically either for a particular app package, or a resource file for a particular package.

Windows requirements

Requirements Description
Device family
Windows 10 (introduced in 10.0.10240.0)
API contract
Windows.Foundation.UniversalApiContract (introduced in v1.0)

Examples

This example is based on scenario 8 of the Application resources and localization sample. See the sample for the complete solution.

private void ShowText()
{
 ResourceContext defaultContextForCurrentView = ResourceContext.GetForCurrentView();
 ResourceMap stringResourcesResourceMap = ResourceManager.Current.MainResourceMap.GetSubtree("Resources");
 Scenario8MessageTextBlock.Text = stringResourcesResourceMap.GetValue("string1", defaultContextForCurrentView).ValueAsString;
}

void Scenario8::ShowText()
{
 ResourceContext^ defaultContextForCurrentView = ResourceContext::GetForCurrentView();
 auto resourceStringMap = ResourceManager::Current->MainResourceMap->GetSubtree("Resources");
 Scenario8MessageTextBlock->Text = resourceStringMap->GetValue("string1", defaultContextForCurrentView)->ValueAsString;
}

Remarks

Resource identifier syntax

Many methods of this class use resource identifiers as parameters. The resource identifier is treated as a Uniform Resource Identifier (URI) fragment, subject to Uniform Resource Identifier (URI) semantics. For example, GetValue("Caption%20") is treated as GetValue("Caption ").

Do not use "?" or "#" in resource identifiers, because they terminate the resource path evaluation. For example, "MyResource?3" is treated as "MyResource".

Properties

Name Description
Size

Gets the number of resources in the map.
Uri

Gets a URI that can be used to refer to this ResourceMap.

Methods

Name Description
First()

Returns an iterator to enumerate the items in the map.
GetSubtree(String)

Returns a ResourceMap that represents a part of another ResourceMap, typically used to access a particular resource file within an app package.

This method finds subtree, ancestor, sibling and cousin maps to this resource map, as well as top-level maps. It returns the resource map represented by a given resource map identifier, relative to this resource map. This method is typically used to make simpler references to a particular subset of resources, such as a single resource file, or a directory of files.
GetValue(String, ResourceContext)

Returns the most appropriate candidate for a resource that is specified by a resource identifier for the supplied context.
GetValue(String)

Note

GetValue(String) may be altered or unavailable for releases after Windows 8.1. Instead, use GetValue(String, ResourceContext).

Returns the most appropriate candidate for a resource that is specified by a resource identifier within the default context.
HasKey(String)

Determines whether the map can retrieve a resource with the specified resource identifier.
Lookup(String)

Returns the NamedResource at the specified resource identifier in the map.
Split(IMapView<String,NamedResource>, IMapView<String,NamedResource>)

Splits the map view into two views.
