实体框架6 T4获取EntitySet名称

Question

I am utilizing the T4 template in EF 6.1.3. Specifically I am creating some additional classes when generated. Stubbing out some basic CRUD methods. I need to access the EntitySet name. The T4 iterates over...

var itemCollection = new EdmMetadataLoader(textTransform.Host, textTransform.Errors).CreateEdmItemCollection(inputFile);

Those objects are of type EntityType . I need to find the associated EntitySet.Name property.

I am stumped and any help is appreciated.

Answer 1

After some digging through some other T4 templates I found a solution. It appears that in previous versions the EF template would utilize the MetadataLoader class and now there is a custom EdmMetadataLoader class in the file itself. This new class did not expose any access to the EntitySet itself.

After getting the Entity collection via...

var itemCollection = new EdmMetadataLoader(textTransform.Host, textTransform.Errors).CreateEdmItemCollection(inputFile);

You can get access to the container...

var container = itemCollection.OfType<EntityContainer>().FirstOrDefault();

Then in the iteration over the entities...

    foreach (var entity in typeMapper.GetItemsToGenerate<EntityType>(itemCollection))
    {
        fileManager.StartNewFile(entity.Name + ".cs");
        var entitySet = container.BaseEntitySets.OfType<EntitySet>().FirstOrDefault(set => set.ElementType == entity);
        ...
    }

Not 100% sure if this is the proper approach, but it does the job and I get the EntitySet name in following property...

entitySet.Name
