protected?override?void?OnModelCreating(ModelBuilder?modelBuilder)?
{
 //取基類=EntityBase?
 var?entityTypes?=?Assembly.GetEntryAssembly().GetTypes()?
????????????????.Where(type?=>?!String.IsNullOrEmpty(type.Namespace))?
????????????????.Where(type?=>?type.GetTypeInfo().BaseType?!=?null?&&?type.GetTypeInfo().BaseType?==?typeof(EntityBase));

 foreach?(var?type?in?entityTypes)?
 {?
 modelBuilder.Model.GetOrAddEntityType(type);?
