title: All rows of specific column in dataset
body: <p>I have a DataSet that looks like this :</p>
  
  <pre><code>| A | B | C | D | E | F | G | H | I | ... |   Z  |
  --------------------------------------------------
  | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | ... |  26  |
  |11 |22 |33 |44 |55 |66 |77 |88 |99 | ... | 2626 |
  |111|222|333|444|555|666|777|888|999| ... |262626|
  </code></pre>
  
  <p>Values <em>not related</em>.  I just have <em>a lot</em> of columns. </p>
  
  <p>I would like to <strong>go through all rows for a specific column</strong>. <br>
  Is it possible without going though all columns ? Because right now the only thing I can think of is this (let's say I want all rows for column D) </p>
  
  <p>C#</p>
  
  <pre><code>foreach(DataRow row in myDataSet.Tables(0).Rows)
     if(row.Column == myDataSet.Tables(0).Columns("D"))
        MessageBox.Show("I'm in Column B");
  </code></pre>
  
  <p>VB</p>
  
  <pre><code>For Each row As DataRow In myDataSet.Tables(0).Rows
  If row.Column Is myDataSet.Tables(0).Columns("D") Then
  MessageBox.Show("I'm in Column B")
  End If
  Next
  </code></pre>
  
  <p>But this would loop through all columns. I would like to use a collection like <br>
  <code>myDataSet.Tables(0).Columns("D").Rows</code> but it does not exist.</p>
