SSIS Package Foreach Loop with File Connection.

This package gives you an idea to get file details and variable mapping between Foreach Loop Container and any inner task contains in loop (here inner task is Script Task).

Step1 : Drag Foreach Loop and script task from SSIS Toolbox.

Step2 : Create one variable with name “FileName” and datatype “string”.
this varialbe maps filename from Foreach Loop Container value to Script task.

Step3 : Right click on Foreach Loop Container –> Edit
On Collection pane –> select Foreach File Enumerator in Enumerator field.
choose your folder by clicking on browse button.
–> Select file extention if you want to filter file extention otherwise put *.* to get all files.
–> Select Name and Extention in Retrieve file name.

Step4 : Select Variable mapping pane on Foreach Loop Editor.
–> Select User::FileName variable.
–> and Index to 0.

Step5 : Right Click on Script Task –> Edit.
–> Select Script Pane –> Select User::FileName as ReadOnlyVarialbe.

Step6 : Click on Edit Scrit to write script code.
