推荐答案

在Mongo 2.6之后，您可以批量进行

After Mongo 2.6 you can do Bulk Updates/Upserts. Example below does bulk update using c# driver.

MongoCollection<foo> collection = database.GetCollection<foo>(collectionName);
      var bulk = collection.InitializeUnorderedBulkOperation();
      foreach (FooDoc fooDoc in fooDocsList)
      {
        var update = new UpdateDocument { {fooDoc.ToBsonDocument() } };
        bulk.Find(Query.EQ("_id", fooDoc.Id)).Upsert().UpdateOne(update);
      }
      BulkWriteResult bwr =  bulk.Execute();
