C#保存txt文档注意事项
1.使用FileStream(string path, FileMode mode, FileAccess access, FileShare share)方法时，特别注意输入 path 对应的文档的名称，请勿包含"\ / : * ? " < > |"特殊字符；
2.创建文件夹区分时，请使用"\\"用于区分；
3.在使用FileStream.Write(byte[] array, int offset, int count)方法时，可以使用 "byte[] writedata = System.Text.Encoding.Default.GetBytes(results);"将string转换成需要的byte[]数组；
