筛选所有查询（尝试实现软删除）

无法测试确切的API，但是一般的方法是创建一个受约束的泛型方法并通过反射进行调用：

public static class EFFilterExtensions{    public static void SetSoftDeleteFilter(this ModelBuilder modelBuilder, Type entityType)    {        SetSoftDeleteFilterMethod.MakeGenericMethod(entityType) .Invoke(null, new object[] { modelBuilder });    }    static readonly MethodInfo SetSoftDeleteFilterMethod = typeof(EFFilterExtensions)    .GetMethods(BindingFlags.Public | BindingFlags.Static)    .Single(t => t.IsGenericMethod && t.Name == "SetSoftDeleteFilter");    public static void SetSoftDeleteFilter<TEntity>(this ModelBuilder modelBuilder)         where TEntity : class, ISoftDeleteModel    {        modelBuilder.Entity<TEntity>().HasQueryFilter(x => !x.IsDeleted);    }}

现在，您可以在您的内部使用类似的内容

OnModelCreating

foreach (var type in modelBuilder.Model.GetEntityTypes()){    if (typeof(ISoftDeleteModel).IsAssignableFrom(type.ClrType))        modelBuilder.SetSoftDeleteFilter(type.ClrType);}
