我來(lái)自C#背景，并使用IO方法，如和來(lái)自命名空間。我有點(diǎn)驚訝地發(fā)現(xiàn)Go沒(méi)有這些IO操作的便利功能。為了避免代碼重復(fù)，我編寫(xiě)了以下幫助程序。有什么理由不這樣做嗎？File.ReadAllLinesFile.WriteAllLinesSystem.IO// WriteBytes writes the passed in bytes to the specified file. Before writing,// if the file already exists, deletes all of its content; otherwise, creates// the file.func WriteBytes(filepath string, bytes []byte) (err error) {    file, err := os.Create(filepath)    if err != nil {        return err    }    defer closeWithErrorPropagation(file, &err)    _, err = file.Write(bytes)    if err != nil {        return err    }    return err}// WriteString writes the passed in sting to the specified file.
