利用bulk添加百万条数据，进行测试

（1）连接数据库

  public static void BulkToDB(DataTable dt)
        {
            //数据库连接
            SqlConnection sqlCon = new SqlConnection("data source=.;initial catalog=Blog;user id=sa;password=123456;multipleactiveresultsets=True;application name=EntityFramework");
            SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlCon);
            //数据表的名称
            bulkCopy.DestinationTableName = "actionlogs";
            bulkCopy.BatchSize = dt.Rows.Count;
            try
            {
                sqlCon.Open();
                if (dt != null && dt.Rows.Count != 0)
                {
                    bulkCopy.WriteToServer(dt);
                }
            }
            catch (Exception ex)
            {

                throw ex;
            }
            finally
            {
                sqlCon.Close();
                if (bulkCopy != null)
                {
                    bulkCopy.Close();
                }
            }
        }

（2）获取要添加数据的表的参数

 public static DataTable GetTableSchema()
        {
            DataTable dt = new DataTable();
            //以下为要添加数据的表的参数设置
            dt.Columns.AddRange(new DataColumn[]
            {
                new DataColumn("Guid",typeof(string)),
                new DataColumn("LoginName",typeof(string)),
                new DataColumn("Name",typeof(string)),                
            });
            return dt;
        }

（3）在Main方法中进行调用，执行

static void Main(string[] args)
        {
            Stopwatch sw = new Stopwatch();
            for(int multiply = 0; multiply < 10; multiply++)
            {
                //获取表的参数
                DataTable dt = Program.GetTableSchema();
                for(int count = multiply * 100000; count < (multiply + 1) * 100000; count++)
                {
                    DataRow dr = dt.NewRow();
                    dr[0] = Guid.NewGuid().ToString();
                    dr[1] = "123456";
                    dr[2] = "郑**";                    
                    dt.Rows.Add(dr);
                }
                sw.Start();
                Program.BulkToDB(dt);
                sw.Stop();
                Console.WriteLine(string.Format("Elapsed Time is {0} Milliseconds", sw.ElapsedMilliseconds));
            }
            Console.ReadLine();
        }
