winform 批量导入本地sql文件，批量导入mdb（access）文件到sqlserver

0.数据库连接

  private void button1_Click(object sender, EventArgs e)
         {
             this.btnUpdate.Enabled = false;
             #region 数据库连接
             connStr.Append("Data Source=");
             connStr.Append(txtServer.Text);

             using (SqlConnection conn = new SqlConnection(connStr.ToString()))
             {
                 //MessageBox.Show(connStr.ToString());
                 ListSql = new List<string>();
                 ListMdb = new List<string>();
                 GetDirectories(Application.StartupPath);
                 //ListSql.Sort(new MySort());

                 foreach (var item in ListSql)
                 {
                     GetSqlFile(item);
                 }
                 foreach (var item in ListMdb)
                 {
                     ReadDataToSQL(item);
                 }
                 MessageBox.Show("升级成功......");
                 this.btnUpdate.Enabled = true;
                 Application.Exit();
             }
             #endregion

         }

1.查找文件与目录

  #region 查找目录与文件
         public void GetDirectories(string path)
         {

             string[] fileNames = Directory.GetFiles(path);
             string[] directories = Directory.GetDirectories(path);
             foreach (string file in fileNames)
             {
                 string str = System.IO.Path.GetFullPath(path);
                 if (System.IO.Path.GetExtension(file).ToLower() == ".sql")
                 {
                     ListSql.Add(file);
                     //GetSqlFile(file);

                     ListMdb.Add(file);
                 }
             }

             foreach (string dir in directories)
             {

         #endregion

2.获取本地脚本文件、执行sql文件

  foreach (var item in ListSql)
                 {
                     GetSqlFile(item);
                 }

                foreach (string str in obj_filelist)
                {
                    this.labShow.Text ="正在执行脚本"+ Path.GetFileName(path)+"文件......";
                    this.ExecSQL(str);
                }
               // MessageBox.Show("导入成功!", "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
            }
            catch
            {

            }
        }

        /// <returns>返回sql文件的执行语句</returns>
        public string GetFileReader(string path)
        {
            try
            {
                using (StreamReader sr = new StreamReader(path, Encoding.Default))
                {
                    String line = sr.ReadToEnd();

                    return line;
                }
            }
            catch (Exception ex)
            {
                return "";
            }
        }
        /// <summary>
        /// 执行SQL
        /// </summary>
        /// <param name="SQL"></param>
        public void ExecSQL(string SQL)
        {
            try
            {
                using (SqlConnection conn = new SqlConnection(@"Data Source=(local);Initial Catalog=数据库名称;User ID=用户名;Password=密码"))
                {
                    conn.Open();
                    using (SqlCommand cmd = new SqlCommand(SQL, conn))
                    {
                        cmd.CommandType = CommandType.Text;
                        cmd.ExecuteNonQuery();
                    }
                    conn.Close();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message + "|" + ex.Source);

            }
        }
        #endregion

3.获取mdb本地文件，执行读取与插入操作

         /// <summary>
         ///读取access数据库中的数据并插入到sqlServer数据库表中
         /// </summary>
