DbSet<MyEntity> set = context.Set<MyEntity>();

或

DbSet set = context.Set( typeof ( MyEntity ) );

或者利用反射,通过实现DbContext的OnModelCreating方法,参考

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);
}
}

DbContext运行时动态附加上一个dbset
