Re asking- C# DLL reading AD Active Directory RRS feed

  • Question

  • Hopefully this is the correct forum.

    I'm new to C#. I first created an EXE that uses AD .

    It works ok. I am now creating a DLL to do the same thing.

      sResults = dSearcher.FindAll();  //  <= this is where it bombs off

    catch(Exception ex)

     InputString = ex.Message.ToString() + ex.HResult.ToString() + Environment.NewLine; // I write this out to a file.

    I get error message  "An operations error occurred."

    HResult =  -2147016672

    I added a manifest to the DLL And I have    <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

    Suggestions on what to try now?

    TIA

    Steve

  • Hi Steve4212,

    >>It works ok. I am now creating a DLL to do the same thingSuggestions

    Do you mean that you create reading AD Active Directory method in c# library project, then generate a DLL file and reference by another project (winforms, or others?), which encounter the issue?

    In addition, did you run the application as administrator? could you please share the steps, which can reproduce the issue, if possible, please share a simple sample via OneDrive. it will be beneficial to resolve the issue.

    Note: please remove privacy information before upload the sample to OneDrive.

    Best regards,

  • I would suspect a permissions issue, but it would help to know what type of app the DLL is running under. You may find more info at the below link that can help:
