It's extraordinary:
1. provides an object-oriented programming environment that fully supports object-oriented programming.
the composition and working principle of the. NET Framework:
The. NET framework runs on top of the operating system and is the most basic framework for . NET . It provides the environment for creating, deploying, and running . NET applications,
primarily contains the common language runtime ( CLR) and framework class libraries, and supports multiple language development. That is, cross-language development.
. NET and java contrast, . NET is a cross-language platform, and java is a cross-platform language.
WPF is One of the core development repositories of the Microsoft Vista operating system.
. NET Compilation technology:
to achieve the strategic goal of cross-platform,. NET All written applications do not compile the cost of code, but compiled into Microsoft intermediate code.
it will be made by The JIT compiler translates into machine code.
System.IO: Support the operation of the file, such as copy and paste delete and read and write to the file.
System.Net: Supports programming of network protocols.
System.Data: Provides class access to the structure that represents the ADO.
System.Drawing: Supports GDI + basic graphics operations.
Object-oriented Review
Classes and objects:
Classes and objects are fundamentally different, classes define a set of conceptual models, and objects are real entities.
Their relationship:
The generalization of objects is the process of generalization.
On the basis of a class, the process of instantiating state and behavior into an object is called instantiation.
Property accessors are divided into three types:
Write-only property: Contains only the set accessor
read-only property: Contains only get accessors
read-write properties: include both set and get accessors
Eg:
Private string _name;
public string Name;
{
Get{return _name};
Set{_name = value};
}
