How to create tables for multiple pipe delimited files and load them dynamically to those tables in SSIS Package


Let's say that we get 100 pipe delimited files and we want to load all of them to different sql server tables. Each of the file has different meta data or column information. 
We want to build an SSIS Package, that can read the column name from the file and then create table and load the data to it and it should repeat for all 100 files. 


To perform this we need to follow below steps.
1. Create an SSIS Package in SQL Server Integration Services Project
2. Create ADO.Net Connection Manager in Connection Managers pane. I have named it ADOAudit. You can name anything but you have to make change in below code accordingly.You will be pointing to the database in which you want to create the tables and load the files.
3. Bring the Script Task to Control Flow pane. Open it and go to Edit Script and paste the below script in it.
4.Change the path of folder in which your files exists for SourceDirectory variable in below code.Save the script and exit the editor. You are done and your SSIS Package is ready to read text files and create table for each of them and load them dynamically in SQL Server Integration Services.
