    Hi Axbeginerss,

    You are saying that It is working fine when we run the batch job manually, are you implement this code in a class which extends RunBaseBatch? Which user is run the batch job?

    If yes, have you implement runsImpersonated method to return true?

    docs.microsoft.com/.../batch-processing-classes

    If still not working, maybe can you try to add below line before GetFiles() to see whether it works?

    #File

    new FileIOPermission(folder, #io_read).assert();

    You're not using AX only. System.IO.DirectoryInfo class is defined in .NET Framework (see documentation). That you're using interoperability with something else and not just AX is also obvious from InteropPermission.

    By the way, please use Insert > Insert Code (int the rich-formatting view) to paste source code. It makes code easier to read and work with.

    System.IO.DirectoryInfo     directory;

       System.IO.FileInfo[]        files;

       System.IO.FileInfo          file;

       InteropPermission           permission;

       Filename                    tmpFilePath;

       Filename                    tmpFileNameShort;

       Filename                    tmpFileExt;

       str         fileNameTemp;

       counter     filesCount;

       counter     loop;

       permission  = new InteropPermission(InteropKind::ClrInterop);

       permission.assert();

       directory   = new System.IO.DirectoryInfo(@"");

       files       = directory.GetFiles();

       filesCount  = files.get_Length();

       for (loop = 0; loop < filesCount; loop++)

       {

           file                                        = files.GetValue(loop);

           fileNameTemp                                = file.get_FullName();

           [tmpFilePath, tmpFileNameShort, tmpFileExt] = fileNameSplit(fileNameTemp);

           this.importExcel(tmpFileNameShort);

       }

       CodeAccessPermission::revertAssert();

    i am using in Ax only. Martin !!

    Your question is about a .NET API, it doesn't seem specific to Dynamics AX, therefore you should look at .NET resources rather then AX resources. This even isn't the best forum.

    Look at C#: How to logon to a share when using DirectoryInfo (at StackOverflow), for example.

    Nevertheless a better approach would be putting the file somewhere where it can be read. If you run your code on server, it's the AOS service account that needs permissions.

    directory = new System.IO.DirectoryInfo(@"XXXXXX");

    files = directory.GetFiles();

    getting the error at files = directory.GetFiles();

    but every time i am accessing the file using Wind+R  it is asking username and password. how to pass username and password through code. ??
