Question

This question have been asked earlier in StackOverFlow and answers are also marked in that post. But sadly the solution provided in
Read a file from an unknown location? does not solve my problem.
I am building a website and need to read data from a text file. The actual location of the file in my pc is: C:\Developments\TestProject\PettyCashSolution\PettyCashWeb\DataFile.txt and I
have tried below solutions from above link with no luck.

string sString = string.Empty;
string sStr = "";
StreamReader oStreamReader;
try
{ 

Try1

sStr = Path.Combine(Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location), "DataFile.txt");

This returns below:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\pettycashweb\af7f0870\c5ac294a\DataFile.txt

Try2

sStr = Path.Combine(Application.StartupPath, "DataFile.txt");

This returns below:
Compile Error: The name “Application” does not exist in the current context

Try3

oStreamReader = new StreamReader(File.OpenRead(Directory.GetCurrentDirectory().ToString() + "\\DataFile.txt"));

This returns below:
Exception: Could not find file ‘C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\DataFile.txt’

oStreamReader = new StreamReader(sStr);
sString = oStreamReader.ReadLine();

}
catch (Exception ex)
{
}

Please also advice what should I do so that after publishing the web in server (iis) the read data from text file will work properly. Thanks.

Answer 1

You can get application path by AppDomain.CurrentDomain.BaseDirectory

Your code must be like this

sStr = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "DataFile.txt");
