How do I open a file (such as .txt) in C#.....
I tried:
String File;
File = txtMain.Text;
dlgOpen.ShowDialog();
File = dlgOpen.FileName;
using (StreamReader sr = new StreamReader(File))
sr.Read(dlgOpen.FileName); <- This line generated errors
\\\\\\\\\\\\\\\\\\
For saving a file I did...
string File;
File = txtMain.Text;
dlgSave.ShowDialog();
File = dlgSave.FileName;
using (StreamWriter sw = new StreamWriter(File))
sw.Write(txtMain.Text);
It worked, so I thought I could do the same for opening a file....Anyway,
anyone has any ideas?? thanks 7 6255
Perhaps, something more like this?
// Declare your file path
strFileName = @"C:\\txtMain.txt";
// Then on to the bigger things
FileStream objFileStream =
new FileStream( strFileName, FileMode.Open, FileAccess.Read );
BufferedStream objBufferedStream =
new BufferedStream( objFileStream );
StreamReader objStreamReader =
new StreamReader( objBufferedReader );
// Read in a line
string strLine;
strLine = objStreamReader.ReadLine();
// whatever code processing code here (if you like)
while ( strLine != null )
{
// continue to read in lines
strLine = objStreamReader.ReadLine();
// your extra code
)
Just an Example of one easy way to get it going for you to get your
feet moving.
I hope it helps at least a bit.

Yes, it would - there's no method StreamReader.Read(string). What are
you trying to do at that point? You've already opened the right file
with the previous line.

You wish to have a dialog box appear from where you can choose the
file to read from ?
perhaps something similar to
private void openSource(object sender, System.EventArgs e)
{
string str_FileName; // your file name is stored in this string
OpenFileDialog fdlg = new OpenFileDialog();
fdlg.Title = "Please choose your text file." ;
fdlg.Filter = "Text Files (*.TXT)|*.TXT";
fdlg.RestoreDirectory = true ;
if(fdlg.ShowDialog() == DialogResult.OK)
{
str_FileName = fdlg.FileName ;
}
}

Check whether file really exists before you use the Dialog.FileName
you can do the same by following lines
openFileDialog1.CheckFileExists = true;
openFileDialog1.CheckPathExists = true;
Thanx Julie,
thats exactly what I needed
