Another block of C# code to convert

T

Ty

Here is another block that I can not get to convert. This is a class
module.

public bool IsAuthenticated(string domain, string username, string
pwd)
{
string domainAndUsername = domain + @"\" + username;
DirectoryEntry entry = new DirectoryEntry( _path,
domainAndUsername, pwd);
try
{
// Bind to the native AdsObject to force authentication.
Object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + username + ")";
search.PropertiesToLoad.Add("cn");
SearchResult result = search.FindOne();
if(null == result)
{
return false;
}
// Update the new path to the user in the directory
_path = result.Path;
_filterAttribute = (String)result.Properties["cn"][0];
}
catch (Exception ex)
{
throw new Exception("Error authenticating user. " + ex.Message);
}
return true;
}

}

Any help would be apperciated.

Hi Seth,

Just for fun.

I saw your code and made this from it, looks for me more as VB 2008

I hope Anton will show what it does with his converter, I expect that it is
better than you showed with those plusses.

Except for using '&' instead of '+' (which may be ambiguous in some cases),
our conversion was quite similar. One difference is that 'DirectCast' is not
the general purpose equivalent for the C# casting operator - CType is a more
reliable replacement (google on DirectCast to see why).

David,

That was the most important for me,
Except for using '&' instead of '+' (which may be ambiguous in some
cases),
our conversion was quite similar.

I made the code particulary for 2008 you should not expect that from a
converter

The guy who did the casting in C# with (string)bla did of course as well not
so a good documentative job, as a ToString() from object is one of the most
basic elements of dotnet.

You mean you posted a part of a class module without telling wich
references were set and without providing the class scoped variabels

The next time provide this information , maybe this is the reasson why
nobody bothered until so far cause the code is pretty simple .


first of all set a refernce to system.DirectoryServices

then in the top of the code file you put this import statement

Imports System.DirectoryServices


Private _path As String
Private _filterAttribute As String


Public Function IsAuthenticated(ByVal domain As String, ByVal
username As String, ByVal pwd As String) As Boolean
Dim domainAndUsername As String = domain + "\" + username
Dim entry As New DirectoryEntry(_path, domainAndUsername, pwd)
Try
' Bind to the native AdsObject to force authentication.
Dim obj As Object = entry.NativeObject
Dim search As New DirectorySearcher(entry)
search.Filter = "(SAMAccountName=" + username + ")"
search.PropertiesToLoad.Add("cn")
Dim result As SearchResult = search.FindOne()
If result Is Nothing Then
Return False
End If
' Update the new path to the user in the directory
_path = result.Path
_filterAttribute =
DirectCast(result.Properties("cn")(0),String)
Catch ex As Exception
Throw New Exception("Error authenticating user. " + ex.Message)
End Try
Return True
End Function
