我无法写入添加到项目中的 txt 文件

Question

31/12/2014 SOLUTION: change filename = @"../../text.txt" I did it successfully ^^ Thank you so much

---

If my text file is determined by a path, for example filename = "C:\\text.txt", I can write data into that file normally.

But if I add text.txt (determined by filename = "text.txt") into my C# project, my program still run without error but nothing is written into text.txt file

Besides I can read txt file (with filename = "text.txt") normally.

Did I miss something? Please help me!

FileStream stream = new FileStream(filename, FileMode.Append);
StreamWriter writeRecord = new StreamWriter(stream);

writeRecord.Write("Random string");
writeRecord.WriteLine();            

writeRecord.Close(); 
stream.Close();

Edit: Sorry Sorry. I also mean that When i added text.txt into C# project. I open file with FileMode.Append and write but data in text.txt file, which i added into project, didn't change

Thank you Kennyzx! I have checked. I really have file text there, but I also i have another text file at [nameproject]\\ that i added into project before didn't change

Answer 1

Try providing the complete file path and file name when specifying the file to open. Rather than "text.txt" use "C:\\YourProjectPath\\YourTextFolder\\text.txt"

Answer 2

Select the text file in your project. Then look in the property window (F4 will show it if you don't have it docked anywhere) for 'Copy to output Directory' and change it from 'Do not copy' to either 'Copy always' or 'Copy if newer'.

After doing this you can read the file using just "text.txt".
