Hi All
I am developing a windows software in C# where I have to create text file and save it to the software root path for that I had given below path\

string datapath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\MyTextFile.txt";

Problem is every time I am writing data and try to save it in my text file but it is overwriting the file which I don't want to overwrite. Can any one please tell me how can I stop overwriting .

Thanks & Regards

Where is your code that writes the file?
I suspect you are ignoring the "append" flag that can be passed when creating a file stream.

If you need to always append data to the same file then Maciej already gave you the solution.
On the other hand, if you need to store each session info into a different file then you may generate a new file with different name each time your application is executed (you may use a persistent counter for this, or a name based on program date and time of execution, ...).
Finally, if you want to modify the existing content of the file then you have first to read it, modify the content in memory and then write back the modified content to the original file.
