Go - read file into string

In this example, we will show you how to read a file into a string in Go with an example.

The ioutil.ReafFile function reads the whole file into a string. This function is convenient but should not be used with very large files.

Go - read the file into a string

The example reads the whole file and prints it to the console.

Let's create a 'sample.txt' file and add the following content to it:

My first fav programming languge is Go Lang
My second fav programming languge is Java
My third fav programming languge is Python

Let's create a file named go_example.go and add the following content to it:


package main

import (
    "fmt"
    "io/ioutil"
    "log"
)

func main() {

    content, err := ioutil.ReadFile("sample.txt")

     if err != nil {
          log.Fatal(err)
     }

    fmt.Println(string(content))
}

Output:

G:\GoLang\examples>go run go_example.go
My first fav programming languge is Go Lang
My second fav programming languge is Java
My third fav programming languge is Python
