//adding a menu object to your project will create code similar to the following:
            private System.Windows.Forms.MainMenu mainMenu1;
            private System.Windows.Forms.MenuItem menuItemFile;
            private System.Windows.Forms.MenuItem menuItemNew;
            private System.Windows.Forms.MenuItem menuItemOpen;
//------------------------------------------------------------------------------------------

private string m_strFileName = "";

/Hold the DialogResult enum result
//Ok or Cancel
private DialogResult dlgResult;

private void menuItemOpen_Click(object sender, System.EventArgs e)
{

    // dlgOpenFile is an OpenFileDialog object
    dlgResult = dlgOpenFile.ShowDialog();
    if(dlgResult == DialogResult.Cancel)
        return;

    try
    {
                // get the file name
        m_strFileName = dlgOpenFile.FileName;
                // open to read that file
        StreamReader sr = new StreamReader(m_strFileName);
                //read the whole file
        txtBody.Text = sr.ReadToEnd();
        sr.Close();
        m_bModified = false;
    }
    catch(Exception err)
    {
        MessageBox.Show(err.Message,"Error",
                         MessageBoxButtons.OK,MessageBoxIcon.Error);
    }
}
