Mapper.CreateMap<Employee, EmployeeDetailsDTO>() .ForSourceMember(mem => mem.NewsPosts, opt => opt. Ignore ()); I want to tell AutoMapper to simply ignore missing properties in the destination object without having to specify each of them. So far, I haven't found a way to do so with my multiple SO and Google searches. Anyone has a solution?
If you want some of the properties not to map with the destination type property then you need to use the AutoMapper Ignore Property in C#. Note: If some of the properties are not available in the destination type, then the AutoMapper will not throw any exception when doing the mapping.
Automapper 4.2 IgnoreAllNonExisting - ignore missing properties Given that Automapper 4.2 has marked the static API as obsolete we shouldn't be using things like Mapper.GetAllTypes () etc. as they will be removed in version 5.
To ignore all unmapped properties using Automapper in C# and VB.NET you can use the following snippet.
In the AutoMapper 2.0, we have an extension method called IgnoreAllNonExisting, which just add a Ignore statement on the properties in the TSource that does not exists in the TDestionation.
By default, AutoMapper tries to map all properties of the source type to the destination type. If some of the properties are not available in the destination type it will not throw an exception when doing the mapping. However it will throw an exception when you are using ValidateMapperConfiguration(). Imagine if we have the following…
Possible duplicate of Automapper v5 Ignore unmapped properties - Michael Freidgeim May 4 '18 at 15:01. The accepted answer of that post does not solve my issue. Therefore, I do not believe this to be a duplicate post. The case is different and the version of AutoMapper is also different.
Is there a way to tell AutoMapper to ignore all of the properties except the ones which are mapped explicitly? I have external DTO classes which are likely to change from the outside and I want to avoid specifying each property to be ignored explicitly, since adding new properties will break the functionality (cause exceptions) when trying to map them into my own objects.

AutoMapper Ignore Property in C#, You can use the Ignore method on the class property to prevent it from mapping to the database column. Usage: Irrespective of whether the configuration is done through Data Annotation or Fluent API, usage of the DBContext would be same. Ignore Properties Attribute Class Definition.
