title: how to get the cell column of a range
body: <p>I'm iterating over a row which I got from a range in order to find a specific word in the cell content and then I want to get the column where I find it. For example, if I find the desired content at the 19th place, it means the the excel column is "S". </p>
  
  <p>Here is the code I'm using so far:</p>
  
  <pre><code>Excel.Worksheet xlWorkSheet = GetWorkSheet(currentWorkBook, "sheet");
  var row = xlWorkSheet.Rows["5"];
  int rowLength = xlWorkSheet.UsedRange.Columns.Count;
  Excel.Range currentTitle = row[1]; //in order to iterate only over the 5th row in this example
    for (int i = 1; i &lt; rowLength; i++)
    {
      string title = currentTitle.Value2[1,i];
      if (title == null)
      {
        continue;
      }
      if (title.Contains(wordToSearch))
      {
        string column = THIS IS THE QUESTION - WHAT DO I NEED TO WRITE HERE?
        Excel.Range valueCell = xlWorkSheet.Range[column + "5"];
        return valueCell.Value2;
      }
  </code></pre>
  
  <p>notice the line of <code>string column</code> in which i need to add the code.</p>
