Web starting with go 1.16, use os.readfile to load the file into memory, and use os.writefile to write to a file from memory ( ioutil.readfile now calls os.readfile and is deprecated). It is also quite useful when starting with a language removing the need initially to access a database. Read files in golang read file. Package main import ( fmt io/ioutil log ) func main () { filecontent, err := ioutil.readfile (gocode.txt) if err != nil { log.fatal (err) } // convert []byte to string text := string. 920 in go 1.1 and newer the most simple way to do this is with a bufio.scanner. Web this function reads the entire file content into a byte slice, and then you can use the “string()” function to read the file content as a string. Web till now i only can search for a string and get true or false result. Buf := new (strings.builder) n, err := io.copy (buf, r) // check errors fmt.println (buf.string ()) outdated information below the short answer is that it it will not be efficient because converting to a string. Web consider the code shown below. B, err := ioutil.readfile (file.txt) // b has type []byte if err != nil { log.fatal (err) } str := string (b)

Here is a simple example that reads lines from a file: Web golang can be used to read files. Read files in golang read file. Web how to read a file in golang.

In go, the readfile() function from the ioutil/os package is used to read a complete file's content/text. Func readfile(filename string) ([]byte, error) readfile reads the file. Buf := new (strings.builder) n, err := io.copy (buf, r) // check errors fmt.println (buf.string ()) outdated information below the short answer is that it it will not be efficient because converting to a string. Golang has many things into the standard library. The os.readfile () function returns a slice of bytes that you can easily convert to a string using the string.
