Exception thrown in api.ListDirectory() when listing a path name containing one or more '\' characters

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Calling api.ListDirectory() function with an ObjectPath that has a pathname 
value that contains a '\' character causes it throw an exception.

e.g. /apache/S1Service/.mauiws/Test\ATMOS/

What is the expected output? What do you see instead?
The function should complete successfully without throwing an exception.

What version of the product are you using? On what operating system?
2.1.4.31

Please provide any additional information below.

I have narrowed down to where the issue seems to be occurring which is at line 
3718 in EsuRestApi.cs. 

protected virtual Uri buildUrl( string resource ) 
{
  return new Uri( protocol + "://" + host + ":" + port + resource );
}

The Uri constructor seems to be changing the '\' character to '/'.

The following error thrown is:

Per the article Microsoft's .Net dev team would decide on fixing it in the 
final release of the .Net 4.0 framework. I am compiling using .Net 4.0 and it 
does not appear to have been fixed.

BTW directory listing for directories with '\' character is working fine with 
ATMOS browser.

I have tried using the Uri.EscapeUriString function to escape the '\' character 
but it is not working.

In addition the URI constructor public Uri(string uriString, bool dontEscape) 
which would have allowed using characters such as '\' has been deprecated and 
does not work with .Net 4.0.

Is there a work around.
