Sort () method of Array class

I just reviewed the sort () method of the Array class. Here I will list some common ones and share them with you.

 

The Array class implements the Bubble Sorting of elements in the Array. The Sort () method requires that the elements in the array implement the IComparable interface. Such as System. Int32

And System. String implement the IComparable interface, so the following Array can use Array. Sort ().

 string[] names = { "Lili", "Heicer", "Lucy" };
Array.Sort(names);
foreach (string n in names) {
    Console.WriteLine(n);
}

Output the sorted array:

 

If you use a custom class for the array, you must implement the IComparable interface. This excuse defines a method CompareTo (). <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4NCjxkaXYgY2xhc3M9 "cnblogs_code" onclick = "cnblogs_code_show (139a6c7f-4e03-446d-a73a-c588771ba92e)"> Person class

 1 public class Person: IComparable {
2 public Person (){}
3 public Person (string name, string sex ){
4 this. Name = name;
5 this. Sex = sex;
6}
7 public string Name;
8 public string Sex;
9
10 public override string ToString (){
11 return this. Name + "" + this. Sex;
12}
13 # region IComparable Member
14 public int CompareTo (object obj ){
15 Person p = obj as Person;
16 if (p = null ){
17 throw new NotImplementedException ();
18}
19 return this. Name. CompareTo (p. Name );
20}
21 # endregion
22}

Here we can sort the Person object array:
