Partial usage of C ＃

lately , In use C# Do procedure .

Before making something , Discover the original C# Code ; After watching the , I feel my head is big ; because , The code is too long , Write thousands of lines for a function class , and , It's all written down like this .

The author keeps one principle in mind ： Good code , It's not for machines , It's for people . See this phenomenon , I don't feel my head is big .

Just think of a principle ： Split thousands of lines of code ; Just right ,C# Provides a partial keyword , It can be done to class、interface Segmentation .

As shown below ：

Source file A1.cs

public partial class A 
{ 
    public void test1();
}

Source file A2.cs

public partial A
{
    public void test2();
}

Equivalent to a source file A.cs

public class A
{
    public void test1();
    public void test2();
}

Quite understand that some engineers write a lot of functions into a class ; because C# Always an object-oriented language , Same and similar functions , The best way is to write into a class with the same . But a lot of code , Obviously, it does not conform to the principles of simplicity and robustness of code .

But it's sad , Not all languages have this feature , Such as JAVA Language does not have this feature ; The solution is to refine the code .

Yes, of course , at present , Push everyone to refactor and optimize the code together .
