What interface did you develop?  Is it a ribbon? tool palette? Is it an external program?

If it's an external program, then you need to use the COM API to access functionality inside autocad from your external program.

Take a look here for someone with the same idea:

You can also search for stand alone applications.  There has been a lot of discussion on this type of thing, but it's not something I've ever explored.

               a.ActiveDocument.SendCommand("TurnLayerOff");

        TurnLayyerOff  is .dll file.but i can't pass textBox2.text to the ,dll file.

You may want to use direct access to all

AutoCAD objects this way instead:

       {

            a = new AcadApplicationClass();
            a.Visible = true;
            string strFileName = @"C:\G4P4-S01.dwg";
            a.Application.Documents.Open(strFileName, false, 1);
            AcadApplication acad = (AcadApplication)a as AcadApplication;
            acad.WindowState = AcWindowState.acMax;
            AcadDocument adoc = (AcadDocument)acad.ActiveDocument as AcadDocument;
            AcadUtility acutil = (AcadUtility)adoc.Utility as AcadUtility;
            string layername = textBox2.Text;
            acutil.Prompt(string.Format("\nLAYER SELECTED\t{0}",layername));
            AcadLayers aclayers = (AcadLayers)adoc.Layers;
            AcadLayer aclayer = aclayers.Item(layername) as AcadLayer;
            if (aclayer == null)
            {
                MessageBox.Show("Layer \"{0}\" does not exist, try another layer name");
                this.textBox2.Select();
                this.textBox2.Text = string.Empty;
                return;
            }
            if (aclayer.ObjectID == adoc.ActiveLayer.ObjectID)
            {
                MessageBox.Show("This is active layer, program exiting...");
                return;
            }
            if (aclayer.LayerOn)
                aclayer.LayerOn = false;
            acutil.Prompt(string.Format("\n\tLAYER \"{0}\" IS OFF", layername));

        }
