title: How can I remove "\r\n" from a string in C#? Can I use a regular expression?
body: <p>I am trying to persist string from an ASP.NET textarea. I need to strip out the carriage return line feeds and then break up whatever is left into a string array of 50 character pieces.</p>
  
  <p>I have this so far</p>
  
  <pre><code>var commentTxt = new string[] { };
  var cmtTb = GridView1.Rows[rowIndex].FindControl("txtComments") as TextBox;
  if (cmtTb != null)
    commentTxt = cmtTb.Text.Length &gt; 50
        ? new[] {cmtTb.Text.Substring(0, 50), cmtTb.Text.Substring(51)}
        : new[] {cmtTb.Text};
  </code></pre>
  
  <p>It works OK, but I am not stripping out the CrLf characters. How do I do this correctly?</p>
