title: Update two columns in a DataTable using LINQ
body: <p>I want to update two columns of DataTable in a single line using LINQ query. Currently I am using following two lines to do the same:</p>
  
  <pre><code>oldSP.Select(string.Format("[itemGuid] = '{0}'", itemGuid)).ToList&lt;DataRow&gt;().ForEach(r =&gt; r["startdate"] = stDate);
  oldSP.Select(string.Format("[itemGuid] = '{0}'", itemGuid)).ToList&lt;DataRow&gt;().ForEach(r =&gt; r["enddate"] = enDate);
  </code></pre>
  
  <p>How can I do this in one line, using one <code>Select</code>?</p>
