Class UmbracoMapper

Umbraco Mapper.

Inheritance
System.Object
Namespace: Umbraco.Cms.Core.Mapping
Assembly: Umbraco.Infrastructure.dll
Syntax
public class UmbracoMapper : IUmbracoMapper
Remarks

When a map is defined from TSource to TTarget, the mapper automatically knows how to map from IEnumerable{TSource} to IEnumerable{TTarget} (using a List{TTarget}) and to TTarget[].

When a map is defined from TSource to TTarget, the mapper automatically uses that map for any source type that inherits from, or implements, TSource.

When a map is defined from TSource to TTarget, the mapper can map to TTarget exclusively and cannot re-use that map for types that would inherit from, or implement, TTarget.

When using the Map{TSource, TTarget}(TSource source, ...) overloads, TSource is explicit. When using the Map{TTarget}(object source, ...) TSource is defined as source.GetType().

In both cases, TTarget is explicit and not typeof(target).
