DbContext运行时动态附加上一个dbset
参考
Creating DbSet Properties Dynamically
C# code?
1 | DbSet<MyEntity> set = context.Set<MyEntity>(); |
或
C# code?
1 | DbSet set = context.Set( typeof ( MyEntity ) ); |
或者利用反射,通过实现DbContext的OnModelCreating方法,参考
Dynamically Adding DbSet Properties in DbContext for Entity Framework Code First
C# code?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | public class MyAppContext : DbContext { protected override void OnModelCreating(DbModelBuilder modelBuilder) { CustomAssemblySection configSection = (CustomAssemblySection)System.Configuration.ConfigurationManager.GetSection( "CustomAssemblySection" ); foreach (CustomAssembly customAssembly in configSection.Assemblies) { Assembly assembly = Assembly.Load(customAssembly.Name); foreach (Type type in assembly.ExportedTypes) { if (type.IsClass) { MethodInfo method = modelBuilder.GetType().GetMethod( "Entity" ); method = method.MakeGenericMethod( new Type[] { type }); method.Invoke(modelBuilder, null ); } } } base .OnModelCreating(modelBuilder); } } |
