C#mongodb driver 2.0-如何在批量操作中进行upsert? [英] C# mongodb driver 2.0 - How to upsert in a bulk operation?

问题描述

我从1.9迁移到2.2，并阅读文档我很惊讶地发现，由于操作不允许使用选项，因此在批量操作期间再也无法进行升级.

I migrated from 1.9 to 2.2 and reading the documentation I was surprised to discover that is not possible to upsert during a bulk operation anymore, since operations don't allow options.

bulkOps.Add(new UpdateOneModel<BsonDocument>(filter, update));
collection.BulkWrite(bulkOps);

应该是

options.isUpsert = true;
bulkOps.Add(new UpdateOneModel<BsonDocument>(filter, update, options));
collection.BulkWrite(bulkOps);

这项工作是否正在进行中，是否有意进行，或者我缺少什么?谢谢.

Is this work in progress, intended, or I'm missing something? Thank you.

推荐答案

设置将UpdateOneModel的IsUpsert 属性设置为true，以将更新转换为upsert.

Set the IsUpsert property of the UpdateOneModel to true to turn the update into an upsert.

var upsertOne = new UpdateOneModel<BsonDocument>(filter, update) { IsUpsert = true };
bulkOps.Add(upsertOne);
collection.BulkWrite(bulkOps);
