Question

I am facing problem while trying to open a simple text file in C#. What i tried so far includes:

• Change the location of file from C dir to D dir.
• Place file inside a folder
• Check its properties and its not read only
• Create new text file from scratch
• Code in C instead of C#

but all the above variations failed and i got the same exception “That file not found”. I am not sure whats wrong there. Its might be some bug in windows 7 or may be some security feature of windows 7 which prevents file from being accessed inside code.

Any help would be highly appreciated.

Edit:
Code in C

FILE *pFile;
    pFile = fopen("d:\\test\\series.txt", "r");

    if (pFile == NULL)
    {
        printf("File not found or Unable to open file\nPress any key to continue . . ." );
        getch();
        return;
    }   
    else
    {
      // do processing here
    }

C# Code:

string[] AllLines = System.IO.File.ReadAllLines("D:\\test\\data.txt");

It’s possible the path isn’t right. Check your file path string, use either the ‘@’ prefix to make it literal, or escape your backslashes as Jeff M suggested.

var filename = @"C:\somedir\somefile.txt";

or

var filename = "c:\\somedir\\somefile.txt";
