Reflection simple example [rotate]

What is assembly (assembly)?
Assembly is a collection of information that contains the name, version number, self-description, file association, and file location of the program. Supported by the Assembly class in the. NET Framework, the class is located under System.Reflection, and the physical location is located at: mscorlib.dll.

What can assembly do?
We can use assembly information to obtain the program's class, instance, and other programming needs.

A simple Demo Example:
1. Establish a console project named: Namespaceref
2. Write the following code:

2UsingSystem.Collections.Generic;
3UsingSystem.Text;
4UsingSystem.Reflection;
5
6NamespaceNamespaceref
7{
8ClassProgram
9{
10 Static voidMain (String[] args)
11{
12Country CY;
13String AssemblyName= @"Namespaceref";
14StringStrongclassname= @"Namespaceref.china";
15 //Note: The class name must be a strong class name here
16//AssemblyName can be found through the AssemblyInfo.cs of the project
17Cy=(country) Assembly.Load (AssemblyName). CreateInstance (Strongclassname);
18Console.WriteLine (Cy.name);
19Console.readkey ();
20}
21st}
22
23ClassCountry
24{
25Public StringName
26}
27
28ClassChinese:country
29{
30PublicChinese ()
31{
32Name= "How are you doing";
33}
34}
35
36ClassAmerica:country
37{
38Public America ()
39         {
40              name = "hello" 41         }
42     }
43

Because of the existence of assembly, we have a better choice in implementing the design pattern.
We sometimes encounter such a problem when we develop, to create the specified object according to the corresponding name. Such as: Give Chinese to create a Chinese object, previously we can only write code like this:

= new China ();
3else if (strongclassname = = america ""
4      cy = new< Span style= "color: #000000;" > America ();

So if we have a long list of objects to create, this code is difficult to maintain and not easy to read. Now we can get an example by defining the assembly name of the class and the strong name of the class in the external file, which is easy to understand and enhances extensibility without modifying the code.
cy = (country) assembly.load (AssemblyName). CreateInstance (Strongclassname);

Conclusion
The Assembly class has a number of methods and properties, which, like type, have many functions for conversions between names and methods and properties. With a deep understanding of these two classes, you can clearly see how the common language layer works.
