what ibase

If IBase is inherited by both the Base class and IA, does Class A inherited from Base and IA inherit the IBase? Test result: Yes So does it inherit from the implementation of the Base class or the implementation in IA? Switch (Who Am I ?) Case (Base)

Section 5 interface implementation 1. explicitly implement interface members To implement the interface, the class can define the explicit interface member execution bodies (explicit interface member implementations ). The explicit interface

Compared with structured data (that is, row data, stored in a database, the two-dimensional table structure can be used to logically express the implemented data, data that is not convenient to use two-dimensional Logical tables in the database is

On the same page, there are multiple groups (not fixed), and the number of blocks in each group is not necessarily the same. You need to expand only one block at a time. For more information, see. The requirement is that there are multiple groups

The requirement is that there are multiple groups (not fixed) on the same page, and the number of blocks in each group is not necessarily the same. only one block needs to be expanded at a time. the implementation principle is actually very simple.

Section 4 access interfaces Access to interface members The rules for calling interface methods and accessing using index indicators are the same as those in the class. If the name of the underlying Member is the same as that of the inherited

Convert any decimal places into 2, 3, 4, 5, 6, 7, 8, and 9 decimal places, retain 8 digits after the decimal point, and output. For example, if the decimal point is 0.795, the output is: Decimal decimal number: 0.795000Decimal decimal number: 0.79500
