I am asking because I am working on a project for school. Yes this is homework. But, I'm trying to understand a little bit more, though.
This is one example of what is being asked.
• When the user clicks the “Save” button, write the selected record to the file specified in txtFilePath (absolute path not relative) without truncating the values currently inside.
private void button2_Click(object sender, EventArgs e)
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
StreamWriter myWriter = new StreamWriter(saveFileDialog1.FileName);
private void button1_Click(object sender, EventArgs e)
if (openFileDialog1.ShowDialog() == DialogResult.OK)
StreamReader myReader = new StreamReader(openFileDialog1.FileName);
txtFilePath.Text = openFileDialog1.FileName;
txtFilePath.Text = myReader.ReadToEnd();
private void Form1_Load(object sender, EventArgs e)
string myFiles = Directory.GetFiles("C:\\");
foreach (string filename in myFiles)
FileInfo file = new FileInfo(filename);
Say you were giving directions to a spot. You have two methods you can describe getting to the location:
Both get you to the same location, but the former doesn't always work ("take a left, then a right, go through two lights then take another right" wouldn't necessarily work from the next town over, but works from where you stand). That's essentially the difference.
If you have
C:\Windows\System32, that's an absolute path. If you have
Windows\System32, it will only work so long as you're starting from
C:\. If you start in
C:\Program Files you would need a
..\ to get there correctly.
However, no matter where you are on the hard drive,
C:\Windows\System32\ is a definitive way to get to that folder.
