C#保存txt文檔注意事項

1.使用FileStream(string path, FileMode mode, FileAccess access, FileShare share)方法時，特別注意輸入 path 對應的文檔的名稱，請勿包含"\ / : * ? " < > |"特殊字符；

2.創建文件夾區分時，請使用"\\"用於區分；

3.在使用FileStream.Write(byte[] array, int offset, int count)方法時，可以使用 "byte[] writedata = System.Text.Encoding.Default.GetBytes(results);"將string轉換成需要的byte[]數組；

            //int length = 0;
            byte[] input = new byte[]{0x03,0x22,0xF1,0x87};
            int length = input.Length;
            byte[] output = new byte[] { 0x30, 0x30, 0x62, 0x68, 0x63, 0x68, 0x61,0x72,0x6C,0x69,0x65,0x2F };
            byte[] data = new byte[]{0x30,0x20,0x50,0x60,0x70,0x40,0x60,0x90 };
            string input_str = "";
            string output_str = "";

            //輸入數據byte數組轉換成hex string
            for(int i = 0; i < input.Length; i++)
            {
                input_str = input_str + input[i].ToString("X2") + " ";
            }

            //輸出數據處理
            for(int j = 0; j < output.Length; j++)
            {
                output_str = output_str + output[j].ToString("X2") + " ";
            }
            //string datastring = System.Text.Encoding.Default.GetString(input);
            int x = 32;
            int y = x % 7;
            Console.WriteLine(y);
            //for(int i = 0; i < length; i++)
            //{
            //    //if(input[i] != null)
            //    //{
            //    data[i] = input[i];
            //    Console.WriteLine("the data details shows below1:" + input[i]);
            //    Console.WriteLine("the data details shows below2:" + data[i]);

            //    //}
            //    //else
            //    //{
            //    //    data[i] = 0x00;
            //    //}
            //}

            Console.WriteLine("the data details shows below:" + data[7]);
