title: C# RichTextBox Select specified Text
body: <p>I have a RichTextBox with -by example- this text:</p>
  
  <pre><code>"This is my Text"
  </code></pre>
  
  <p>Now I want to "search" the RichTextBox for a Text (String), by example: </p>
  
  <pre><code>"Text"
  </code></pre>
  
  <p>Now "Text" should be selected/highlighted (for each one) in the RichTextBox..</p>
  
  <p>There is something like:</p>
  
  <pre><code>myRichTextBox.Select();
  </code></pre>
  
  <p>but here I have to set a StartPosition and so on, but I want to search for String!</p>
  
  <p>How could I do this? (Searched stackoverflow, didn't find something similiar..)</p>
