.net core 如何在Graphql.NET查询中选择items子列表？

查询“customer”返回一个id==传递参数的项

{customer(id: 3){id,firstName,lastName,email}}

如何创建查询“customer4”，选择通过参数传递的列表中id所在的客户子列表？ 例如，电话

{customer4(id: [3,5]){id,firstName,lastName,email}}


    var graphList = new QueryArguments(new QueryArgument<NonNullGraphType<ListGraphType<IntGraphType>>> { Name = "id", Description = "Customer Id" });

    var graphList2 = new QueryArguments(new QueryArgument<NonNullGraphType<IntGraphType>> { Name = "id", Description = "Customer Id" });
    Field<CustomerGraphType>("customer", "Returns a Single Customer",
            graphList2,
            context => _appContext.Customers.Single(x => x.Id == context.Arguments["id"].GetPropertyValue<int>()));

    Field<ListGraphType<CustomerGraphType>>("customer4", "Returns a Customers Sub-list",
        graphList2,
        context => _appContext.Customers.Any(x => x.Id == context.Arguments["id"].GetPropertyValue<int>()));

{customer4（id:[3,5]）{id，firstName，lastName，email}
var graphList=newqueryarguments（newqueryarguments{Name=“id”，Description=“Customer id”}）；
var graphList2=新查询项（新查询项{Name=“id”，Description=“Customer id”}）；
字段（“客户”，“返回单个客户”，
笔划师2，
context=>\u appContext.Customers.Single（x=>x.Id==context.Arguments[“Id”].GetPropertyValue（））；
字段（“customer4”，“返回客户子列表”，
笔划师2，
context=>_appContext.Customers.Any（x=>x.Id==context.Arguments[“Id”].GetPropertyValue（））；
