BGjohn Member	Posted on 13/11/2021 at 05:21:08 by BGjohn Member Hi! I am writing a program in C# and I am looking for creating a text file and writing data in this file during the execution. I also don't want the program to overwrite the file. I want the data to be written at the end of an existing file. Can you help to find the correct function to do that? Thanks!

And do not forget to use the namespace System.IO. Here is the syntax: using System.IO; StreamWriter file = new StreamWriter(@"C:\filename.txt", true); //open the file (and create it if it does not already exist) //true means not to overwrite the file but to write at the end of the existing file file.WriteLine("The text to write."); //write text to the file. file.Close(); //close the file. You can find more information here: https://docs.microsoft.com/en-us/dotnet/api/system.io.streamwriter.-ctor?view=net-5.0#System_IO_StreamWriter__ctor_System_String_System_Boolean_ Please let me know if you need more help. 😉 Good luck! --------------------------
