如何加入两个可查询的查询

Question

我想连接两个易查询，两个都通过过滤两个条件来获得结果集，无论查询连接还是结果集连接我都想将结果作为内部连接 这是我的代码

我真的想做这样的事情

var joinedquery = query.Join(query2)


var query = filteredVehicle
                    .Join(VehiclePolicy, m => m.Id, n => n.VehicleId, (m, n) => new { m, n })

                    .Join(Contracti, q => q.p.ContractId, r => r.Id, (q, r) => new { q, r })
