C# Byte[]數組讀取和寫入文件

這個項目我用的是asp.net構建的，代碼如下

 protected void ByteToString_Click(object sender, EventArgs e)
        {


            string content = this.txtContent.Text.ToString();

            if (string.IsNullOrEmpty(content))
            {
                return;
            }

            //string 轉為byte數組
            byte[] array = Encoding.UTF8.GetBytes(content);

            //將byte數組轉為string
            string result = Encoding.UTF8.GetString(array);


            Response.Write(result);


        }
        //利用byte[]數組寫入文件
        protected void writerFile_Click(object sender, EventArgs e)
        {

            string content = this.txtContent.Text.ToString();

            if (string.IsNullOrEmpty(content))
            {
                return;
            }

            //將string轉為byte數組
            byte[] array = Encoding.UTF8.GetBytes(content);

            string path = Server.MapPath("/test.txt");
            //創建一個文件流
            FileStream fs = new FileStream(path, FileMode.Create);

            //將byte數組寫入文件中
            fs.Write(array, 0, array.Length);
            //所有流類型都要關閉流，否則會出現內存泄露問題
            fs.Close();

            Response.Write("保存文件成功");


        }
        //利用byte[]數組讀取文件
        protected void readFile_Click(object sender, EventArgs e)
        {
            string path = Server.MapPath("/test.txt");

            FileStream fs = new FileStream(path, FileMode.Open);

            //獲取文件大小
            long size = fs.Length;

            byte[] array = new byte[size];

            //將文件讀到byte數組中
            fs.Read(array, 0, array.Length);

            fs.Close();

            //將byte數組轉為string
            string result = Encoding.UTF8.GetString(array);


            Response.Write(result);

            

        }
