C#. Join (merge) some text files into one
The task. We have 3 separated text files, for example, web server logs. For more comfortable analyze we want to join them into one file. Below my simple solution for this task in C#.
The main steps of script are:
- Read directory and get filenames. Add names to array of string
- Loop through array of filenames, read contents of files and add it to string collection List<string> stringList
- Join string collection List<string> to a string variable
- Write result to textFile
Full code of console application below. It's the simple version. You may add more features to a code if you want to.
