method executes a callback when each piece of data returns. To achieve the purpose of concurrent processing, such as the following code demonstrates how to use:
Collection. Find (New Bsondocument ()). Foreachasync (x => Console.WriteLine (x));
Querying a single piece of data by condition
We can call the Find method by passing in a filter condition to query the list of the data we want, such as the following example we will query the field "counter" value of 71 data:
var fi
OverviewThe builder pattern is a more complex creation pattern that separates the client from the creation of complex objects that contain multiple components (or parts), and the client does not need to know the internal components and assembly methods of complex objects, only the type of builder required. It is concerned with how to create a complex object step by step, different concrete builders define different creation processes, and the concrete

Personal Understanding:
The construction of a complex object is separated from its representation, allowing the same build process to create different representations.
After searching for a number of builder models, I found that some of the builders ' goals were to encapsulate the product in different order, some of the same order of different products, the order was encapsulated in the director, and some were not encapsulated, but deferred to the

The builder pattern separates complex constructs from their representations, and the same build process can create different representations. The difference between the builder model and the abstract factory is that in the builder model there is a mentor, the mentor who manages the builders, the user interacts with the mentor, the Mentor contacts the builder, and finally gets the product we need. That is, the builder model can enforce a process of co
performance.
The builder pattern is the pattern that is applied when the algorithm for creating complex objects should be independent of the components of the object and the way they are assembled.
The builder model includes product class (products), abstract Builder Class (Builder), Concrete builder class (ConcreteBuilder1, ConcreteBuilder2 ...). ) and conductor class (Director)

, configuration files in many cases the impact of the development efficiency.There are few profiles in rails (but not no, database connection is a profile), and rails ' fans are 10 times times more efficient than Java development, which is probably the reason. MAVEN also uses the COC principle, when you execute the mvn-compile command, you do not need to refer to where the source files are placed, and after the compilation of the class file is not specified anywhere, this is the COC principle.2.

the same method of the scene, different execution order, produce different event results, multiple parts or parts can be assembled into an object, but the result is different, the product class is very complex, or the order of call in the product class produces different performance, This is a good time to use builder mode, when initializing an object is particularly complex, such as many parameters, and many parameters have default values. 2 Builder Mode UML class diagram General
