Reading all text files in a network path in a WinForms app

How can i read all the text files in a network path in C# Winforms?. The text files name are always changing.

example:

• ABC-GD09538.txt


• ADB-JK3949.txt


• GJD-KGL9495-txt

The format of each text file when opened is:

Some Text
Some Text
Some Text
Some Text

[data start]
"Data1"|"Data2"|"Data3"|"Data4"|"Data5"|"Data5"|"Data6"
[data end]

I would also like to ignore the "some text" part of text file and proceed the text file reading on the line [data start] and end it on the line [data end] then finally perform a query to database and then insert the data received from text files to a table.
