Finding path and creating a file.

Question

5.00/5 (1 vote)

See more:

C#

string path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location + @"\keyfile\EmailbodyorFile.txt");

I used this to get the path,but my problem is 'EmailbodyorFile.txt' must be created automatically during runtime and the above code do not create the file.So what to do?

Earlier I used this code ,

C#

string path = Path.GetFullPath(System.AppDomain.CurrentDomain.BaseDirectory + @"\keyfile\EmailbodyorFile.txt");

and it run correctly,but after creating setup of project, it shows error 'File not found error'.

please help.

Could I suggest that you do the following? Use the 'dot notation' to locate the file.
var text = File.ReadAllLines(@".\MyFolder\MyFile.txt");
This reads 'MyFile.txt' from the 'executing assembly'\MyFolder
Also, use a try catch block to catch FileNotFoundException

You can make use of File.Create method to create/overwrite the file at desired path.

Actually your code has a bit of a problem, I think, you misplaced ')'. You used it at the end of the whole string instead of using it after 'Location' like this

C#

System.Reflection.Assembly.GetExecutingAssembly().Location + @"\keyfile\EmailbodyorFile.txt");

which in result gives you the location, but with your \keyfile.

I tried and run the code to see what path does it return and i got this by running this code:

C#

Console.WriteLine(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location + @"\keyfile\EmailbodyorFile.txt"))

the output was:
c:\users\USERNAME\documents\visual studio 2015\Projects\CODEPROJECT\CODEPROJECT\bin\Debug\CODEPROJECT.exe\keyfile

So, The right way to do it is this:

C#

System.Reflection.Assembly.GetExecutingAssembly().Location) + @"\keyfile\EmailbodyorFile.txt";

Which will return this path:
c:\users\USERNAME\documents\visual studio 2015\Projects\CODEPROJECT\CODEPROJECT\bin\Debug\keyfile\EmailbodyorFile.txt

And for checking the existence of directory and file you can use this code:

C#

string dir = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + @"\keyfile";
string filePath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + @"\keyfile\EmailbodyorFile.txt";

Start:
  if (System.IO.Directory.Exists(dir)) {
    if (System.IO.File.Exists(filePath)) {
      //DoStuff();
    } else {
      System.IO.File.WriteAllText(filePath, "/*your data*/");
      goto Start;
    }
  } else { System.IO.Directory.CreateDirectory(dir); goto Start; }

I hope you understood what I wrote :) .
