I don't know whether it's a pleasant surprise or a depressing situation.

In March, I will resign and work with mm to study for my postgraduate students. I have been deeply touched by my work for three years. I must use these three years to complete my English and basic knowledge, this is a good choice.

The documents about URL rewriting translated after the test in March have never been pasted. I have seen too many bad and scolded translation words, however, I still tried to apply for a public blog with xpilot, And I posted it to my favorites. I felt quite fulfilled! :) Hoho, it seems a little arrogant? Be humble ......

Now, I come to the conclusion that it is a common task to share and express what I think (people, things, Code, etc.). It's easy to use!

I saw the C # Class Library Design Manual for a while last night and found that I really lacked a lot of basic knowledge.
This time I understood the difference between a superficial copy and a deep copy. Code It seems correct, but a slight change can improve some performance, such: // Obtain a superficial copy
Public Getdataset1 () {
Dataset DS= NewDataset ();
//Fill in a dataset, omitted


ReturnDS. Clone ();
}

// Obtain a deep copy
Public Getdataset2 () {
Dataset DS= NewDataset ();
//Fill in a dataset, omitted


ReturnDS;
}

If DS is a book and getdataset () is a book borrowing operation, let's look at the two differences:
To obtain a superficial copy is to directly connect this book to the reader (Getdataset1 ())
To obtain a deep copy, save (or destroy) the book and copy it to the reader (Getdataset2 ())
I want to lend books to readers directly, which is better than copying books to readers. The system will have these minor performance differences soon, so pay attention to them later.
