  you need sql code
  

  INSERT INTO TABLE2 (COL1, COL2, COL3) SELECT COL1, COL4, COL7 FROM TABLE1​

  try this ​

  
  
  with ADO.Net concepts apply the above query over database table and you get desired results

  Bulk Copy feature of ADO.NET might help you take a look at that: #-Link-Snipped-#

  This is the simplest way to copy a table into another (new) table in the same SQL Server database. This way of copying does not copy constraints and indexes.

  select * into  from 
   
   
  Example:
  Select * into employee_backup from employee

  We can also select only a few columns into the destination table like below

  select col1, col2, col3 into 
  from 
   
  Example:
  Select empId, empFirstName, empLastName, emgAge into employee_backup
  from employee

  Use this to copy only the structure of the source table.

  select * into  from  where 1 = 2
   
  Example:
  select * into employee_backup from employee where 1=2

  Use this to copy a table across two database in the same Sql Server.

  select * into 
  from 
   
  Example:
  select * into Mydatabase2.dbo.employee_backup
  from mydatabase1.dbo.employee

  Any one of the following methods can be employed to copy a table into a destination database on a different SQL Server.

  1. Data Transformation Service (DTS) – SQL Server 2000.
  2. SQL Server Integration Service (SSIS) – SQL Server 2005
  3. SQL Server “Export Data” task. – SQL Server 2000/2005
  4. Create a linked Server of the destination SQL Server on the source SQL Server and then copy the table. – SQL Server 2000/ 2005.
  5. We can also use My code library (SQL Server T-SQL code samples, snippets, examples, tips, tricks, stored procedures, user defined functions, VB programs): Narayana Vyas Kondreddi's home page to generate data insertion scripts and then run the insert scripts.
  6. I almost forgot this 😉 you can open the source table , select the row(s), copy (ctrl + C) the row(s), open the destination table and then paste (ctrl + V) the row(s).
