您可以使用同步 InsertOne() 方法或异步 InsertOneAsync() 方法将单个文档插入到集合中。
例子
以下示例将文档插入 restaurants 集合。
选择 Asynchronous 或 Synchronous 标签页，查看相应的代码。
// Generates a new restaurant documentRestaurant newRestaurant = new(){ Name = "Mongo's Pizza", RestaurantId = "12345", Cuisine = "Pizza", Address = new() { Street = "Pizza St", ZipCode = "10003" }, Borough = "Manhattan",};
// Asynchronously inserts the new document into the restaurants collectionawait _restaurantsCollection.InsertOneAsync(newRestaurant);有关 InsertOneAsync() 操作的完全可运行示例，请参阅异步插入一个示例。
// Generates a new restaurant documentRestaurant newRestaurant = new(){ Name = "Mongo's Pizza", RestaurantId = "12345", Cuisine = "Pizza", Address = new() { Street = "Pizza St", ZipCode = "10003" }, Borough = "Manhattan",};
// Inserts the new document into the restaurants collection_restaurantsCollection.InsertOne(newRestaurant);有关 InsertOne() 操作的完全可运行示例，请参阅同步插入一个示例。
预期结果
在运行上述任一完整示例后，InsertOne() 方法会插入该文档，而 Find() 方法会返回新插入的文档。输出类似于以下内容：
Inserting a document...Document Inserted: { "_id" : ObjectId("..."), "name" : "Mongo's Pizza", "restaurant_id" : "12345", "cuisine" : "Pizza", "address" : { "_t" : "MongoDB.Bson.BsonDocument, MongoDB.Bson", "_v" : { "street" : "Pizza St", "zipcode" : "10003" } }, "borough" : "Manhattan", "grades" : [{ "_t" : "MongoDB.Bson.BsonDocument, MongoDB.Bson", "_v" : { } }] }更多信息
