Accessing Internal Classes from External Assemblies
In certain scenarios, you may encounter a situation where an assembly you are using provides a method that returns an object type, but that object actually belongs to an internal class within the inaccessible assembly. This raises the question of how to access the fields and methods of that internal class from your own assembly.
Solution: InternalsVisibleTo
While modifying the vendor-supplied assembly is out of the question, there is a solution if you wish to allow specific assemblies access to the internal members of the vendor assembly for testing purposes. This can be achieved using the InternalsVisibleTo attribute.
In the AssemblyInfo.cs file of your project, add the following line:
[assembly: InternalsVisibleTo("name of assembly here")]
This line grants the specified assembly access to the internal members of your assembly, including the internal class you are trying to access.
Usage
Once you have added the InternalsVisibleTo attribute and rebuilt your assembly, you can access the internal class from your external assembly as follows:
public class MyClass { public void AccessTest() { Vendor vendor = new Vendor(); object value = vendor.Tag; // Cast the object to the internal class type InternalClass internalClass = (InternalClass)value; // Access the internal member string test = internalClass.test; } }
Note: It's important to ensure that the assembly you grant access to is used for testing purposes only, as it can compromise the security of your application if used in production.

C is still important in modern programming because of its efficient, flexible and powerful nature. 1)C supports object-oriented programming, suitable for system programming, game development and embedded systems. 2) Polymorphism is the highlight of C, allowing the call to derived class methods through base class pointers or references to enhance the flexibility and scalability of the code.

The performance differences between C# and C are mainly reflected in execution speed and resource management: 1) C usually performs better in numerical calculations and string operations because it is closer to hardware and has no additional overhead such as garbage collection; 2) C# is more concise in multi-threaded programming, but its performance is slightly inferior to C; 3) Which language to choose should be determined based on project requirements and team technology stack.

C is widely used and important in the modern world. 1) In game development, C is widely used for its high performance and polymorphism, such as UnrealEngine and Unity. 2) In financial trading systems, C's low latency and high throughput make it the first choice, suitable for high-frequency trading and real-time data analysis.

There are four commonly used XML libraries in C: TinyXML-2, PugiXML, Xerces-C, and RapidXML. 1.TinyXML-2 is suitable for environments with limited resources, lightweight but limited functions. 2. PugiXML is fast and supports XPath query, suitable for complex XML structures. 3.Xerces-C is powerful, supports DOM and SAX resolution, and is suitable for complex processing. 4. RapidXML focuses on performance and parses extremely fast, but does not support XPath queries.

C interacts with XML through third-party libraries (such as TinyXML, Pugixml, Xerces-C). 1) Use the library to parse XML files and convert them into C-processable data structures. 2) When generating XML, convert the C data structure to XML format. 3) In practical applications, XML is often used for configuration files and data exchange to improve development efficiency.

The main differences between C# and C are syntax, performance and application scenarios. 1) The C# syntax is more concise, supports garbage collection, and is suitable for .NET framework development. 2) C has higher performance and requires manual memory management, which is often used in system programming and game development.

The history and evolution of C# and C are unique, and the future prospects are also different. 1.C was invented by BjarneStroustrup in 1983 to introduce object-oriented programming into the C language. Its evolution process includes multiple standardizations, such as C 11 introducing auto keywords and lambda expressions, C 20 introducing concepts and coroutines, and will focus on performance and system-level programming in the future. 2.C# was released by Microsoft in 2000. Combining the advantages of C and Java, its evolution focuses on simplicity and productivity. For example, C#2.0 introduced generics and C#5.0 introduced asynchronous programming, which will focus on developers' productivity and cloud computing in the future.
