Ask a weak question: List

wangkui_77

List <T>
What exactly does this thing mean and what is its use? I often see methods written like this
public List <string> CutWord (string str)
{
 
}
There are other same methods, all have this: <>.
Don't understand
Please tell me more about it

Simply put, all the strings in the list must be strings

Generics, I also do n’t understand this stuff, I used a lot of generics in this last project
I did n’t write it.
I don't quite understand generics yet.

Simply speaking:

List <T> is equivalent to a collection of objects, the common situation is: the bonding of controls such as Gridview

This sounds very simple

What is generic, I will look at the information

The C++ template indicates that there is a linked list, and each element is of type string. If the parameter is int, then each element is of type int.
It is recommended to look at the usage of templates

The generic usage of C# can be List<int> List<char>...
<>You can put any type inside, similar to the template in C++, which means a string type list
