写入Txt文件方法

   private static void WriteTxt(string fullFilepath, string Content)
        {
            StreamWriter Sw1 = null;
            try
            {

                CreatePath(GetFilePath(fullFilepath));
                Sw1 = new StreamWriter(fullFilepath, true, Encoding.UTF8);
                {
                    Sw1.WriteLine(Content);
                }
            }
            catch (Exception ef)
            {
                throw new Exception(ef.Message);
            }
            finally
            {
                try
                {
                    Sw1.Close();
                }
                catch
                {
                }
            }
        }

去出文件所有路径

 public static string GetFilePath(string FileName)
        {
            string sFile = FileName;
            sFile = sFile.Substring(0, sFile.LastIndexOf("\"));
            return sFile;
        }

创建路径

 public static bool CreatePath(string path)
        {
            try
            {
                if (!HasFilePath(GetFilePath(path)))
                {
                    CreatePath(GetFilePath(path));
                }
                Directory.CreateDirectory(path);
                return true;
            }
            catch (Exception ee)
            {
                throw new Exception(ee.Message);
            }
        }

文件所在路径是否存在

  public static bool HasFilePath(string FileName)
        {
            if ((FileName.Length == 2) && (FileName.LastIndexOf(':') > 0))
                return true;
            return Directory.Exists(GetFilePath(FileName));
        }
