This is relatively simple to do provided you have permission to access both files, and permission to create a new file in the directory you intend to create it in.

So, what have you tried ? Show some code. We are not going to do your homework, or your coding, for you.

Hi, try this code, and refer System.IO namespace in your project.

C#

string FirstFileContents = File.ReadAllText("your first file path here");
string SecondFileContents = File.ReadAllText("your second file path here");
StringBuilder ThirdFileContents = new StringBuilder();
ThirdFileContents.Append(ThirdFileContents.ToString());

File.WriteAllText("your third file path here", ThirdFileContents);

You're lacking the basic idea here.
First you need to read the text from both the files, store it in some object/collection (whichever you prefer) and then write it to some different file.
(Make sure that you have appropriate permissions to access the file.)

Look at this & you're good to go then,
Read from a File[^]
Write to a File[^]
