MongoDB C# Driver 2.0 - Update document

由 吃可爱长大的小学妹 提交于 2019-11-27 13:30:30
I'm currently upgrading my code to MongoDB C# driver 2.0 and I'm having issues upgrading the code to update documents. using the old version I was able to do something like this: MyType myObject; // passed in var collection = _database.GetCollection<MyType>("myTypes"); var result = collection.Save(myObject); I'm struggling to find a way to do this in the new version. I have found a few examples of updating single fields like var filter = Builders<MyType>.Filter.Eq(s => s.Id, id); var update = Builders<MyType>.Update.Set(s => s.Description, description); var result = await collection

问题 I am writing a very, very simple query which just gets a document from a collection according to its unique Id. After some frusteration (I am new to mongo and the async / await programming model), I figured this out: IMongoCollection<TModel> collection = // ... FindOptions<TModel> options = new FindOptions<TModel> { Limit = 1 }; IAsyncCursor<TModel> task = await collection.FindAsync(x => x.Id.Equals(id), options); List<TModel> list = await task.ToListAsync(); TModel result = list
