打开文件时FileNotFound异常

Question

I have a project that reads several text files into a List via StreamReader, I have the files added to my solution under Resources, when I try to reference the file using StreamReader, I get a "FileNotFound" exception.

The files are being copied over to bin\\debug\\Resources, and the error says it's trying to locate them under bin\\debug.. How do I reference them without using the literal path? (eg C:\\users\\etc) since when I compile it won't run on another person's PC if I reference actual path.

Code that calls text file:

using (sr = new StreamReader("FileName.txt"))
{
    while (!sr.EndOfStream)
        Names.Add(sr.ReadLine());
}

Under the text files properties I have it set to "Copy Always" and under Build Action it's set to "Embedded Resource".

Basically my main goal is to compile the project into an exe with the text files being referenced internally (their contents aren't changed by the program), so my application will be portable.

Answer 1

In your situation, the error will be removed by just replacing the path Resources\\FileName.txt

In other case, as you mentioned that you want to make a portable .exe. Then you need to embed files in your application. Now see how to embed files in your .exe :

• Expand Properties in Solution Explorer

• Double click on Resources

  On left top of Resources tab, there will be a combo box

• Choose Files

• Now just drag and drop your files there
• To embed files, you can go to properties of every file by right clicking on it. Choose Embedded in .resx from Persistence property.

To use the file you can use Properties.Resources.YourFile .

Answer 2

Error is clear. Change code to:

using (sr = new StreamReader("Resources\FileName.txt"))
{
    while (!sr.EndOfStream)
        Names.Add(sr.ReadLine());
}
