How to add text file in my project so that it is not visible to user..?

Sir,

I am developing an application in which i am to save some information in text file. During execution, I wish to read/write data from/to the file(.txt file). I dont want the file to be visible to user. Or if it is visible then it must be in programfile folder of the system and user could not delete the data of the file. What should i do? I tried to add the file in Resource file but could not read and write the file. PLease help me to read/write OR provide some ot开发者_JS百科her way to implement the same(described above).

Thanks in advance....

Don't use ProgramFiles (installation) folder: 1. File will be visible for user 2. If user won't have admin rights your app will fail on modifying the file. Windows System folder is also question of rights. I'd advice to use system registry or appdata folder: you can get it Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData). You'll be able to write to that location without admin rights. You should create some special subfolder there (not needed, but would be convinient). Or in registry case: writing to registry:

string myEncrStringToSave;    
Microsoft.Win32.RegistryKey key;
key = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("Software\\Your_Cpecial_Key");
key.SetValue("Software\\Your_Cpecial_Key", myEncrStringToSave);
key.Close();  

reading from registry:

Microsoft.Win32.RegistryKey key;
key = Microsoft.Win32.Registry.CurrentUser.CreateSubKey("Software\\Your_Cpecial_Key");
object value = key.GetValue("Software\\Your_Cpecial_Key");
if (value!=null)
   string myEncryptedString = value.ToString();
key.Close();

Your_Cpecial_Key here is some identifier (like in hashtable) that allows you to get access to your data.

you could use IsolatedStorage, it's not fully hidden but at least not easily discoverable as well.

Put the file in the Windows System folder and use it from there.

You can access it without giving full path by using Environment.SpecialFolder.System.

This way user will have to work hard in order to find the file, but in case he does find you can't really prevent him from changing it as it's the same user running your program.

I am not sure if this might help you. You may make the text file as an Embedded resource and get the same via

Assembly assm = Assembly.GetExecutingAssembly();
StreamReader aread = new StreamReader(assm.GetManifestResourceStream("Namespace.TextFile1.txt"));

So this is not accessible to the user nor available in the deployed location
