EntityFrameworkCore.IncludeFilter 根据EntityFrameworkCore 2.1.0进行了修改 如何使用： public void ConfigureServices ( IServiceCollection services ) { ... services . AddDbContext < DbContext>( options => options . UseSqlServer ( " connection_string " ) . AddIncludeWithFilterMethods ()); ... } var children = dbContext . Parent . IncludeWithFilter ( p => p . Children , c => c . Active )
