| <h4 class="dtH4">Property Value</h4> |
| <p> The name of the current user, or <code>NOT AVAILABLE</code> when the underlying runtime has no support for retrieving the name of the current user. </p> |
| <h4 class="dtH4">Remarks</h4> |
| <p> Calls <code>WindowsIdentity.GetCurrent().Name</code> to get the name of the current windows user. </p> |
| <p> To improve performance, we could cache the string representation of the name, and reuse that as long as the identity stayed constant. Once the identity changed, we would need to re-assign and re-render the string. </p> |
| <p> However, the <code>WindowsIdentity.GetCurrent()</code> call seems to return different objects every time, so the current implementation doesn't do this type of caching. </p> |
| <p> Timing for these operations: </p> |
| <div class="tablediv"><table class="dtTABLE" cellspacing="0"><tr valign="top"> |
| <th width="50%">Method</th> |
| <th width="50%">Results</th> |
| </tr><tr valign="top"> |
| <td><code>WindowsIdentity.GetCurrent()</code></td> |
| <td>10000 loops, 00:00:00.2031250 seconds</td> |
| </tr><tr valign="top"> |
| <td><code>WindowsIdentity.GetCurrent().Name</code></td> |
| <td>10000 loops, 00:00:08.0468750 seconds</td> |
| </tr></table></div> |
| <p> This means we could speed things up almost 40 times by caching the value of the <code>WindowsIdentity.GetCurrent().Name</code> property, since this takes (8.04-0.20) = 7.84375 seconds. </p> |
