SQLSERVER_SqlBulkCopy批量添加使用

直接上代码了

         static void Main(string[] args)
        {
            string conn = @"Initial Catalog=aaa;Data Source = 192.168.1.1; Integrated Security = False; User ID = sa; Password=123;MultipleActiveResultSets=True;Encrypt=False;TrustServerCertificate=False";

  
            SqlBulkCopyByDatatable(conn, "Permission", GetTableSchema());

        }

　　

        static void SqlBulkCopyByDatatable(string connectionString, string TableName, DataTable dt)
        {
            using (SqlConnection conn = new SqlConnection(connectionString))
            {
                using (SqlBulkCopy sqlbulkcopy = new SqlBulkCopy(connectionString, SqlBulkCopyOptions.UseInternalTransaction))
                {
                    try
                    {
                        sqlbulkcopy.DestinationTableName = TableName;
                        for (int i = 0; i < dt.Columns.Count; i++)
                        {
                            sqlbulkcopy.ColumnMappings.Add(dt.Columns[i].ColumnName, dt.Columns[i].ColumnName);
                        }
                        sqlbulkcopy.WriteToServer(dt);
                    }
                    catch (System.Exception ex)

　　//下面的案例是带Stopwatch 测试耗时

                }
            }
        }

　　表字段，与上面一样。

        static DataTable GetTableSchemas()
        {
            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[] {
 new DataColumn("Id",typeof(Guid)),
 new DataColumn("MenuID",typeof(Guid)),
  new DataColumn("MenuFunctionID",typeof(Guid)),
 new DataColumn("RoleID",typeof(Guid)),
  new DataColumn("UserId",typeof(Guid)),
 new DataColumn("PerStr",typeof(Boolean)),
  new DataColumn("ParentId",typeof(Guid)),
 new DataColumn("PlantId",typeof(Guid)),
  new DataColumn("CreateTime",typeof(DateTime)),
 new DataColumn("Remark",typeof(string)),
  new DataColumn("UpdateTime",typeof(DateTime)),
 new DataColumn("DeleteState",typeof(int)),
 new DataColumn("CreateUserId",typeof(Guid)),
  new DataColumn("CreateUserName",typeof(string)),
  new DataColumn("UpdateUserId",typeof(Guid)),
 new DataColumn("UpdateUserName",typeof(string))});



            return dt;
        }

　　记录时间

        static int GetMinute(long l)
        {
            return (Int32)l / 60000;
        }
