title: Select statamen of a Datarow array
body: <p>I have the following code, first I filter by a foreign key, but then with that result I need to filter more with dates.</p>
  
  <p>But I cant understand the syntax of the <code>select()</code> method of a datarow array given below.</p>
  
  <pre><code> UC021_WizardStepSelectUnitDataSet.WizardStepSelectUnits_UnitsSelectedInOtherAgreementsRow[] datarows =
                      _uc021_WizardStepSelectUnitDataSet.WizardStepSelectUnits_UnitsSelectedInOtherAgreements.Select(
                          "UnitId = " + row.UnitID).Cast
                          &lt;UC021_WizardStepSelectUnitDataSet.WizardStepSelectUnits_UnitsSelectedInOtherAgreementsRow&gt;().ToArray();
  
                  DataRow[] dr = _uc021_WizardStepSelectUnitDataSet.
                      WizardStepSelectUnits_UnitsSelectedInOtherAgreements.Select(
                          "UnitId = " + row.UnitID);
  
                  if (datarows.Length &gt; 0)
                  {
                      dr.Select("");
                  }
  </code></pre>
