而不是使用anonymous选择new { .. }对象，请尝试使用new DAL.model() { ... }进行以下操作。

public IQueryable<DAL.model> GetAllmodels()
{
    var models = (from d in db.models
                  where (d.Model_Deleted == false)
                  select (
                  new DAL.model()
                  {
                      Model_ID = d.Model_ID,
                      Model_Name = d.Model_Name,
                      Model_Image = d.Model_Image
                  })).AsQueryable();

    return models;
}
