用于复杂查询的MongoDB C#数组筛选器

Question

使用MongoDB C#/.NET驱动程序版本2.11.5。这是我的收藏结构。

CollectionName:部署

                },
                {

                }               
            ]
        },
        {
            "name" : "Policy-2",
            "description" : "Policy-2",
            "rules" : [ 
                {
                    "subject" : "mno.pqr@xyz.com",
                    "status" : "InProgress",
                    "comments" : "",
                    "updatedBy" : "",

                },
                {
                    "subject" : "stu.vwx@xyz.com",
                    "status" : "InProgress",
                    "comments" : "",
                    "updatedBy" : "",
                    "approvalId" : "2z0c8767-6613-4aa2-9b87-7778a42512ee",
                    "requestDate" : ISODate("2021-02-11T08:29:32.000Z")
                }               
            ]
        }
    ]
}

C#类名：

部署(有多个IList<Policy> Policies)

策略(有多个IList<Rule> Rules)

规则

更新规则中的状态、注释和updatedBy字段的更新查询是什么，给定Policy.Name (对于ex: Policy-1)和Rule.subject (对于ex: updatedBy)

1. 什么是插入查询以在策略中插入一个新的规则对象，给定Policy.Name (对于ex: Policy-1)?

谢谢你的帮助。

关于这个问题-

Querying, filtering and updating multiple level nested arrays in MongoDB using C#

我已经执行了以下内容，并如预期的那样起了作用。

    var updateFilter = Builders<Deployment>.Filter.Eq(f => f.Id, deployment.Id);
        
    var updateBuilder = Builders<Deployment>.Update
.Set("policies.$[i].rules.$[j].comments", rule.Comments)
.Set("policies.$[i].rules.$[j].completionDate", rule.CompletionDate)
.Set("policies.$[i].rules.$[j].status", Enum.GetName(rule.Status))
.Set("policies.$[i].rules.$[j].updatedBy", rule.UpdatedBy);
        
    var arrayFilters = new List<ArrayFilterDefinition>()
                {
new BsonDocumentArrayFilterDefinition<Policy>(new BsonDocument("i.name", policy.Name)),
new BsonDocumentArrayFilterDefinition<Rule>(new BsonDocument("j.subject", rule.Subject))
                };
        
    var updateOptions = new UpdateOptions()
                {
                  ArrayFilters = arrayFilters
                };
        
    await _deploymentRepository.UpdateOneAsync(updateFilter, updateBuilder, updateOptions);
