Reading a text file into a textBox

simplicitylabs

This doesn't throw any errors, but it also doesn't put the contents of my file into the textBox...

    private void ReadFromFile(string\[\] filename)
    {
        // create reader & open file
        TextReader tr = new StreamReader(openFileDialog1.FileName);

        // read a line of text
        this.textBox1.Text = tr.ReadLine();

        // close the stream
        tr.Close();
    }

Where am I going wrong?

try tr.ReadToEnd method please. I think the first line is a blank string in your file.

When I saw your suggestion, I got excited. But, alas, there was no happy ending. To put it in context, I'm including the openfiledialog as well.

    private void openToolStripButton\_Click(object sender, EventArgs e)
    {
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            this.openFileDialog1.InitialDirectory = @"c:\\";
        }
    }

    private void ReadFromFile(string filename)
    {
        // create reader & open file
        TextReader tr = new System.IO.StreamReader(this.openFileDialog1.FileName);

        // read a line of text
        this.textBox1.Text = tr.ReadToEnd();

        // close the stream
        tr.Close();
    }

If you have any more suggestions, I'm all ears.

Oops, missed that. Thanks for the catch. Added it...now it just locks up. By the way, did I say or do something wrong???

If you're using .NET 2.0, System.IO.File.ReadAllText(openfileDialog1.FileName) should do it ( or something similar )

I sugguest you check the value of the openFileDialog1.FileName.Make sure that's a file's real path. If this way cannot help you try these codes: //First ,create a txt file at C:\ // create reader & open file TextReader tr = new StreamReader(@"c:\1.txt"); // read a line of text this.textBox1.Text = tr.ReadLine(); // close the stream tr.Close(); Good luck.
