                        {
                            System.Diagnostics.Process.Start(open.FileName);

------解决方案--------------------
发重了.
------解决方案--------------------
如果openFileDialog1.ShowDialog() 的返回值是DialogResult.OK
那你可以用openFileDialog1.Filename做你想做的事情啊!
------解决方案--------------------
private void button4_Click(object sender, EventArgs e)  
       {  
               if (openFileDialog1.ShowDialog() == DialogResult.OK)
               {
                  /////你自己想做的事
               }
  
       }
------解决方案--------------------
private void button1_Click(object sender, System.EventArgs e)
{
    Stream myStream = null;
    OpenFileDialog openFileDialog1 = new OpenFileDialog();
    openFileDialog1.InitialDirectory = "c:\\" ;
    openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
    openFileDialog1.FilterIndex = 2 ;
    openFileDialog1.RestoreDirectory = true ;
    if(openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        try
        {
            if ((myStream = openFileDialog1.OpenFile()) != null)
            {
                using (myStream)
                {
                    // Insert code to read the stream here.
                }
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
        }
    }
