title: What is the fastest way to load text file into RichTextBox?
body: <p>I load text file into RichTextBox using OpenFIleDialog. But when a large amount of text is (for example song text about 50-70 lines) and I click OPEN program hangs for a few second (~3-5). Is it normal? Maybe there is some faster way or component to load text file? If my question is an inappropriate just delete it. Thanx.</p>
  
  <pre><code>if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
          {
              string text = File.ReadAllText(openFileDialog1.FileName);
              for (int i = 0; i &lt; text.Length - 1; i++)
              {
                  richTextBox1.Text = text;
              }
          }
  </code></pre>
  
  <p>I guess maybe <code>ReadAllLines</code> impeds it?</p>
