title: How to handle Column '<ColumnName>' does not belong to table
body: <p>i have a scenario where some <code>column</code> name of a <code>DataTable</code> may not be present. Because i am creating a dynamic <code>DataTable</code>. </p>
  
  <pre><code>DataTable tbl = new DataTable();
  tbl.Columns.Add("Roll");
  tbl.Columns.Add("Name");
  DataRow dr = tbl.NewRow();
  dr["Name"] = "Arshad";
  dr["Roll"] = 1;
  tbl.Rows.Add(dr);
  Console.WriteLine(dr["Address"]);// exception, or
  Console.WriteLine(Convert.ToString(dr["Address"]));
  </code></pre>
  
  <p>I want to check whether this <code>DataTable</code> contains a <code>column</code> called Address or not. Is it possible like we have in <code>Dictionary</code> like:</p>
  
  <pre><code>if (objDictionary.ContainsKey("Address"))
   {
   }
  </code></pre>
