Add and display CAD files in ae9.2

Many people in the Forum mentioned that the display CAD cannot be loaded in ae9.2. I carefully studied that ae9.1 and ae9.2 have different ways to load CAD.CodeContributed for your reference (I have tested and can use it)

Private void opencadfile ()
{
// Set Workspace
Iworkspacefactory pworkspacefact = new cadworkspacefactoryclass ();
// Open the Workspace
Iworkspace pworkspace;
Pworkspace = pworkspacefact. openfromfile (@ "E: \", 0 );

// set caddrawingworkspace
icaddrawingworkspace pcaddwgworkspace = (icaddrawingworkspace) pworkspace;
// open the caddrawingdataset
deployment workflow;
workflow = pcaddwgworkspace. opencaddrawingdataset ("15413422.dwg");

// Open the CAD image in mapcontrol
If (pcaddwgdataset = NULL) return;
Icadlayer pcadlayer = new cadlayerclass ();
Pcadlayer. caddrawingdataset = pcaddwgdataset;

This. axmapcontrol1.addlayer (pcadlayer, 0 );

}
