How can I list all files in Go language?

In Go language, you can use the ReadDir function in the ioutil package to list all files and folders in a specific directory. Here is a simple example code:

package main

import (
	"fmt"
	"io/ioutil"
)

func main() {
	dir := "./"  // 指定目录

	files, err := ioutil.ReadDir(dir)
	if err != nil {
		fmt.Println("读取目录失败：", err)
		return
	}

	for _, file := range files {
		fmt.Println(file.Name())
	}
}

In the example above, we specified the directory to list files from as the current directory (./). The ioutil.ReadDir function will return a slice of type []os.FileInfo, which contains information about all the files and folders in the directory. By iterating through this slice, we can access the name of each file.
