Putting each line from a text file into an array C#

arrays, c#, foreach, text-files, winforms

Solution

I am not sure what your question is since you seemed to have answered it. If you want us to review it you question would be better suited to Code Review: https://codereview.stackexchange.com/

If you want to use MSDN look here: http://msdn.microsoft.com/en-us/library/System.IO.File_methods(v=vs.110).aspx

Spoiler alert, here is how I would do it:

    string[] lines = null;
    try
    {
        lines = File.ReadAllLines(path);
    }
    catch(Exception ex)
    {
        // inform user or log depending on your usage scenario
    }

    if(lines != null)
    {
        // do something with lines
    }

Problem

I am working on selecting a text file with a folder pathway via a Windows form in C# and gathering information on each pathway. At the minute, I can import the file and display only the second pathway in the text file, but no information on the folder. Here is the code I have: ``` private void btnFilePath_Click(object sender, EventArgs e) { //creating a stream and setting its value to null Stream myStream = null; //allowing the user select the file by searching for it OpenFileDialog open = new OpenFileDialog(); open.InitialDirectory = "c:\\"; open.Filter = "txt files (*.txt)|*.txt"; open.FilterIndex = 2; open.RestoreDirectory = true; //if statement to print the contents of the file to the text box if (open.ShowDialog() == DialogResult.OK) { try { if ((myStream = open.OpenFile()) != null) { using (myStream) { txtFilePath.Text = string.Format("{0}", open.FileName); if (txtFilePath.Text != "") { lstFileContents.Text = System.IO.File.ReadAllText(txtFilePath.Text); //counting the lines in the text file using (var input = File.OpenText(txtFilePath.Text)) { while (input.ReadLine() != null) { //getting the info lstFileContents.Items.Add("" + pathway); pathway = input.ReadLine(); getSize(); getFiles(); getFolders(); getInfo(); result++; } MessageBox.Show("The number of lines is: " + result, ""); lstFileContents.Items.Add(result); } } else { //display a message box if there is no address MessageBox.Show("Enter a valid address.", "Not a valid address."); } } } } catch (Exception ex) { MessageBox.Show("Error: Could not read the file from disk. Original error: " + ex.Message); } } } ``` I was thinking that copying each line to a variable using a foreach or putting each line into an array and looping through it to gather the information. Can anyone advise me which would be most suitable so I can go to MSDN and learn for myself, because, I'd prefer to learn it instead of being given the code. Thanks!
