.net - Get paper size of the layer in autocad c# -

i have method create layout. want set width , height of layout can't find properties.

how , set dimension of layout ?

you need call setcanonicalmedianame correct paper size available. check sample below

[commandmethod("setclosestmedianamecmd")] public void setclosestmedianamecmd() {     document doc = application.documentmanager.mdiactivedocument;     database db = doc.database;     editor ed = doc.editor;      plotsettingsvalidator psv = plotsettingsvalidator.current;      // let's first select device     stringcollection devlist = psv.getplotdevicelist();      ed.writemessage("\n--- plotting devices ---");      (int = 0; < devlist.count; ++i)     {         ed.writemessage("\n{0} - {1}", i+1, devlist[i]);     }      promptintegeroptions opts = new promptintegeroptions(         "\nenter device number: ");      opts.lowerlimit = 1;     opts.upperlimit = devlist.count;     promptintegerresult pir = ed.getinteger(opts);      if(pir.status != promptstatus.ok)         return;      string device = devlist[pir.value - 1];      promptdoubleoptions pdo1 = new promptdoubleoptions(         "\nenter media height(mm): ");      promptdoubleresult pdr1 = ed.getdouble(pdo1);      if (pdr1.status != promptstatus.ok)         return;      promptdoubleoptions pdo2 = new promptdoubleoptions(         "\nenter media width(mm): ");      promptdoubleresult pdr2 = ed.getdouble(pdo2);      if (pdr2.status != promptstatus.ok)         return;      using (transaction tx = db.transactionmanager.starttransaction())     {         layoutmanager layoutmgr = layoutmanager.current;          layout layout = tx.getobject(             layoutmgr.getlayoutid(layoutmgr.currentlayout),             openmode.forwrite)                  layout;          setclosestmedianame(             psv, device, layout,             pdr1.value, pdr2.value,             plotpaperunit.millimeters, true);          tx.commit();     } }  void setclosestmedianame(plotsettingsvalidator psv,     string device,     layout layout,     double pagewidth,     double pageheight,     plotpaperunit units,     bool matchprintablearea)    {     psv.setplottype(         layout,         autodesk.autocad.databaseservices.plottype.extents);      psv.setplotpaperunits(layout, units);     psv.setusestandardscale(layout, false);     psv.setstdscaletype(layout, stdscaletype.scaletofit);     psv.setplotconfigurationname(layout, device, null);     psv.refreshlists(layout);      stringcollection medialist =         psv.getcanonicalmedianamelist(layout);      double smallestoffset = 0.0;     string selectedmedia = string.empty;     plotrotation selectedrot = plotrotation.degrees000;      foreach(string media in medialist)     {         psv.setcanonicalmedianame(layout, media);         psv.setplotpaperunits(layout, units);          double mediapagewidth = layout.plotpapersize.x;         double mediapageheight = layout.plotpapersize.y;          if(matchprintablearea)         {               mediapagewidth  -=                   (layout.plotpapermargins.minpoint.x +                    layout.plotpapermargins.maxpoint.x);                mediapageheight -=                   (layout.plotpapermargins.minpoint.y +                    layout.plotpapermargins.maxpoint.y);         }          plotrotation rotationtype = plotrotation.degrees090;          //check not outside media print area         if(mediapagewidth < pagewidth ||            mediapageheight < pageheight)         {               //check if 90°rot fit, otherwise check next media               if(mediapageheight < pagewidth ||                  mediapagewidth >= pageheight)               {                     //too small, let's check next media                     continue;               }                //that's ok 90°rot fit               rotationtype = plotrotation.degrees090;         }          double offset = math.abs(             mediapagewidth * mediapageheight -             pagewidth * pageheight);          if (selectedmedia == string.empty || offset < smallestoffset)         {             selectedmedia = media;             smallestoffset = offset;             selectedrot = rotationtype;              //found perfect match can quit             if (smallestoffset == 0)                 break;         }     }      psv.setcanonicalmedianame(layout, selectedmedia);     psv.setplotrotation(layout, selectedrot);      string localmedia = psv.getlocalemedianame(         layout,         selectedmedia);      editor ed = application.documentmanager.mdiactivedocument.editor;      ed.writemessage("\n - closest media: " + localmedia);     ed.writemessage("\n - offset: " + smallestoffset.tostring());     ed.writemessage("\n - rotation: " + selectedrot.tostring()); }
