Final answer:
The design pattern applied in ADO .Net to encapsulate the requests of actions as an object is A. Command. This pattern allows decoupling of the requester and receiver.
Step-by-step explanation:
The design pattern that is applied in ADO .Net to encapsulate the requests of actions as an object is A. Command.
The Command design pattern is a behavioral pattern that converts a request into a separate object, allowing the requester to be decoupled from the receiver. In ADO .Net, the DbCommand class is an example of this pattern. It represents a command to be executed against a data source, encapsulating the details of the operation.
For example, in ADO .Net, you can create a DbCommand object to encapsulate a SQL query and execute it using the ExecuteNonQuery method. The CommandText property of the DbCommand object holds the query, and the ExecuteNonQuery method sends the query for execution.
