【MS CE C++】通过ElementPropertiesSetterPtr 如何设置线型 linestyle

线型分系统线型（0~7）和自定义线型。如果是前者，直接用整数设置即可。

如果是后者，需要调用LineStyleManager::GetNumberFromName从自定义线型名得到这个对应的UInt32整数，然后再传入pPropsSetter->SetLinestyle中

你好， 符工，线串生成成功之后设置线型并没有改变，请问什么原因，代码如下：

MSElementDescrP addBPOutPath1(DPoint3d *pathPoins)
	{
		//外框1路径
		DPoint3d *pathPoint = new DPoint3d[3];

		DPoint3d outp3 = pathPoins[0];
		pathPoint[0] = outp3;

		DPoint3d outp4 = pathPoins[1];
		pathPoint[1] = outp4;

		DPoint3d endp = pathPoins[1];
		endp.z = pathPoins[0].z;
		DPoint3d outp5 = zy_pointAsDistance(pathPoins[0], endp, LANGDAO1_W / 2);
		outp5.z = pathPoins[1].z;
		pathPoint[2] = outp5;

		MSElementDescrP edp1;
		MSElement el1;
		mdlLineString_create(&el1, NULL, pathPoint, 3);
		mdlElmdscr_new(&edp1, NULL, &el1);
		mdlElmdscr_add(edp1);

		EditElementHandle eeh(edp1, false, false);
		ElementPropertiesSetterPtr pPropsSetter = ElementPropertiesSetter::Create();
		pPropsSetter->SetLinestyle(4, NULL);
		pPropsSetter->Apply(eeh);
		eeh.ReplaceInModel(eeh.GetElementRef());

		delete[]pathPoint;
		return edp1;
	}

请不要在CE下还去调用老的MSElementDescr了。这个只在万不得已时才用到。

可直接调用LineStringHandler::CreateLineStringElement创建LineString的eeh，SetLineStyle后调用AddToModel添加到模型中即可。

明白了，符工，谢谢
