- 别名可以直接比较 type MyStudent1 = Student
|
||
|
|
- 属性字段一样，可以通过类型转换进行比较

```Go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import "fmt"
|
||
|
|
|
||
|
|
type Student struct {
|
||
|
|
Name string
|
||
|
|
}
|
||
|
|
|
||
|
|
type StudentAnother struct {
|
||
|
|
Name string
|
||
|
|
}
|
||
|
|
|
||
|
|
type MyStudent Student
|
||
|
|
type MyStudent1 = Student
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
s1 := Student{Name: "1"}
|
||
|
|
s2 := MyStudent{Name: "1"}
|
||
|
|
s3 := MyStudent1{Name: "1"}
|
||
|
|
s4 := StudentAnother{Name: "1"}
|
||
|
|
fmt.Printf("s1: %T\n", s1)
|
||
|
|
fmt.Printf("s2: %T\n", s2)
|
||
|
|
fmt.Printf("s3: %T\n", s3)
|
||
|
|
fmt.Printf("s4: %T\n", s4)
|
||
|
|
// fmt.Printf("(s1 == s2): %v\n", (s1 == s2))
|
||
|
|
fmt.Printf("(s1 == s3): %v\n", (s1 == s3))
|
||
|
|
fmt.Printf("(s1 == Student(s4)): %v\n", (s1 == Student(s4)))
|
||
|
|
}
|

```
