 public static void BulkInsert<T>(string connection ,string tableName, IList<T> list)

        {
            using (var bulkCopy = new SqlBulkCopy(connection))
            {
                bulkCopy.BatchSize = list.Count;
                bulkCopy.DestinationTableName = tableName;
                var table = new DataTable();
                var props = TypeDescriptor.GetProperties(typeof(T))
                                           .Cast<PropertyDescriptor>()
                                           .Where(propertyInfo => propertyInfo.PropertyType.Namespace.Equals("System"))
                                           .ToArray();
                foreach (var propertyInfo in props)
                {
                    bulkCopy.ColumnMappings.Add(propertyInfo.Name, propertyInfo.Name);
                    table.Columns.Add(propertyInfo.Name, Nullable.GetUnderlyingType(propertyInfo.PropertyType) ?? propertyInfo.PropertyType);
                }
                var values = new object[props.Length];
                foreach (var item in list)
                {
                    for (var i = 0; i < values.Length; i++)
                    {
                        values[i] = props[i].GetValue(item);
                    }
                    table.Rows.Add(values);
                }
                bulkCopy.WriteToServer(table);
            }
        }
